Learn about the differences between paper documents and digital documents, their pros and cons, and in which situations each should be used.

In an ongoing debate about paper documents and digital documents, the latter seem to be winning, as most companies, agencies, and organizations are transitioning to a digital format. The reason is that electronic documents are

 accessible, cost-effective, and take up significantly less space

However, the benefits of paper documents can’t be overlooked, either, especially when they are still widely used. In many cases, they are still 

considered more official and safer than the digital ones

In this article, we will compare paper documents vs. digital documents, discuss their pros and cons, and determine when it’s best to use each. We will also show you how to transition from paper to digital documents if you wish to modernize your office and reduce clutter.

Key differences between digital and physical documents are security, storage and space, retrieval, searchability, collaboration options, environmental impact, and cost.

Paper documents are still often used for financial records and official documentation, like contracts, deeds, birth certificates, and more.

Meanwhile, digital documents are becoming the preferred document type because they are easy to access, share, and store.

If you want to transition from paper documents to digital documents, you need to prepare and organize your files, select a scanning method, pick a naming convention for your new digital documents, and upload them all to a cloud-based storage system.

physical records created by writing or typing on paper

, typically kept in filing cabinets or safes. Although their digitization is in full swing, they remain crucial for official documentation and 

. As a result, many contracts, deeds, birth and 

, letters, and personnel files are still in paper form.

Paper documents are still widely used because they come with several advantages. Here are some of those:

. Paper documents exist in the physical, tangible space, so they can’t be targeted and accessed by hackers. Because of that, they are sometimes considered the safer option, though that depends on the security level.

. Since these documents aren’t digitally stored, they can be opened even when the power is out or computer systems are down. For a similar reason, they are more reliable, as you’re not in danger of losing them due to a system failure.

. Physical signatures are often held in higher regard than digital or 

, so many agencies and government departments still require them.

. If something happens to computer systems and storage, paper documents of the contracts and deeds saved digitally can serve as a backup. This ensures that your documents aren’t lost, so it’s best to keep tangible copies of important records on hand.

However, the disadvantages of paper documents can sometimes outweigh the benefits, which is why their digital versions are largely preferred. Let’s take a look at some of these cons:

. One of the most frequent problems with paper documents is storage, as they need to be kept in drawers and filing cabinets. So, if you have many, you may struggle to find space for them, and even when you do, they create a lot of clutter.

. Paper documents may deteriorate over time or experience other kinds of damage that can affect their contents. Furthermore, they are vulnerable to fires, floods, and other types of disasters.

. The paper used for this type of document contributes to deforestation and waste.

. A well-organized archive of paper documents can make it easier to find what you’re looking for, but there’s no way to search for specific words or phrases within the document. This can make it difficult to look for particular information, and the entire process may take longer than necessary.

files created to store specific information in an electronic format

 rather than on paper. As a result, these require digital devices, like laptops or smartphones, for viewing. Nowadays, they’re largely becoming the preferred format, so most people and organizations use 

, DOCX files, emails, and spreadsheets to store and share information.

The many benefits of digital documents are the reason they are so widely used today. Here are a few of the most prominent ones:

. The management of digital documents is far simpler than that of paper files, as they are stored on electronic devices and organized in folders. In other words, there’s no need for large physical spaces and filing cabinets that take up most of the room. Plus, 

 makes it far easier to find what you’re looking for.

. If specific settings are enabled, multiple users can view and edit digital documents simultaneously, which makes them indispensable for remote work. This also saves the time it would take to deliver paper documents to each person who needs to access them.

. Unlike paper documents, digital documents leave no waste and don’t contribute to deforestation, making them a more eco-friendly option.

. Electronic documents can be backed up to the cloud, which prevents data loss in case of a disaster. So, even if your devices are damaged and no longer functional, the documents are still intact and accessible.

Despite their many advantages, digital documents do have a few significant downsides that are worth mentioning, such as:

 and password protection can significantly improve the security of digital documents, they are still at risk of cyberattacks. This is especially concerning for highly confidential documents containing private information.

. When opening digital documents, you may experience issues with software compatibility, which can result in difficulties accessing the file. These are easily resolved in most cases, but they may cause inconveniences, especially when you need to view the document urgently.

. In general, easy storage is a big advantage, but it can become an issue over time. That’s because technology changes, software evolves, and many of the formats that used to be the norm become obsolete. As a result, documents that could be easily accessed before may no longer be accessible.

. Transitioning to a digital format can be expensive at first, since these documents require significant investments in hardware and software. Also, the staff responsible for documentation and archiving needs to be trained to handle the transition, which may take up extra time and resources.

Key Differences Between Paper and Digital Documents

The key differences between paper and digital documents include 

storage and space, security levels, retrieval, collaboration, searchability, costs, and environmental impact

We’ve covered most of these aspects previously, but now we’ll stack them up against each other in this paper vs. digital documents comparison table:

It’s best to use paper documents in specific situations, such as:

 are just as valid as handwritten ones, many government agencies still require a wet signature on their records. So, wills, birth certificates, marriage certificates, property deeds, and similar documents are typically kept in paper form instead of being digitized.

. If you believe there’s a risk of a cyberattack and data breach despite the protection methods you’ve implemented, it’s best to stick to paper documents. That’s especially the case with those containing highly confidential data, such as financial information.

. Paper format still wins over digital when it comes to permanent storage, as technology changes very fast, and the current one may become obsolete in a few years. You can update your records whenever these changes happen, but it’s easier and safer to create a physical archive and keep permanent records there.

. If you live in an area with a poor internet connection or frequent power outages, digital documents aren’t an ideal solution. You’ll lose access to them as soon as the power’s out, so it’s better to use paper documents, at least as backups.

Digital documents are becoming a staple, so you’ll be expected to use them in most situations. However, here are a few where they might play a bigger role:

. If you work remotely, most of the documentation you receive and handle will likely be digital, since this is far more convenient than using mail to send it back and forth. Plus, you’ll likely often collaborate with other team members on different types of documents, editing and 

. In some workplaces, it’s crucial to access documents or data within them as quickly as possible, in which case paper files aren’t particularly convenient. Digital documents are far easier to search, and the required information can be found within minutes.

. If you’re in a small office that doesn’t have a large storage capacity, you should digitize your documents whenever possible. This allows you to save up space while still retaining access to all your files.

. Since paper documents are vulnerable to damage and deterioration, you can use their digital versions as secure backups. However, make sure to implement strong enough protection to prevent potential data breaches.

How to Transition From Paper to Digital Documents

To transition from paper to digital documents, you need to 

organize your documents, select a scanning method, rename the digital files for easier access, and save them to a cloud-based storage system

Now, we’ll take you through the process step by step:

If you have plenty of documents to convert from paper to a digital format, you need to sort them and choose which to start with. It might take time to complete the transition, so it’s best to begin with the most important ones, as well as 

decide whether you need to convert them all

For instance, if you have any documents for permanent records, you don’t have to convert them to a digital form. As mentioned before, these are best kept as paper documents, though you can create electronic backups if it helps you feel safer.

The most common ways to convert paper documents into digital documents are by 

scanning them with your phone or with an actual scanner

. The former is typically used in informal settings when you only have a few documents to scan, while the latter is more suitable for companies with many files.

If you opt for your phone, you can use built-in features, like 

Google Drive for Android or Notes for iPhone

. Both allow you to take a photo of the document with your camera and save it as a PDF or 

However, if you choose to use a scanner, select a high-quality one and 

use Optical Character Recognition (OCR) software

 to make the scans searchable and editable. You may even partner up with a document scanning company that can convert all your paper documents into digital ones.

Once you have your PDF scans, make sure to 

 for your digital files and ensure they are all neatly organized into dedicated folders. That way, you’ll have an easier time retrieving them when you need to.

#4. Save Your Files to a Cloud-Based Storage System

Rather than keeping your files on a local device, 

upload them to Google Drive, Dropbox, or another 

 to keep them safe and easily accessible. Even if your device malfunctions, you can retrieve your documents on a different one, as long as you have the right credentials.

Once you’ve digitized your documents and converted them into PDF files, 

. Our PDF editor has it all: it allows you to split, merge, and annotate content, sign electronic documents, and 

. Moreover, you can share your work with others and involve them in the editing process.

Now that you understand the main differences between PDFs and printed documents, you can make a more informed decision about the format that suits your needs.

In general, we recommend digitizing your files to save storage space and enable easy access to them, no matter where you are. However, you should still make some room for physical copies and paper backups.

#3. Are digital documents more secure than paper documents?

Digital documents can be more secure than paper documents 

if proper protection methods have been implemented

. For example, if your digital records use encryption, password protection, and access tracking, then they’re safer to use than paper documents. However, there’s always a risk of potential cyberattacks.


Digital vs. Paper Documents: Pros, Cons, & When to Choose Each

The answer to “Why are my PDF files so large?” is that they are scanned or contain details like embedded fonts, multimedia, metadata, etc.

because they contain high-resolution images, embedded fonts, unnecessary metadata, and complex design elements or multimedia

. They can also be ‘inflated’ because they are scanned and saved as images rather than text-based files.

In this guide, we will cover the common reasons why PDFs inflate in size and provide practical tips to resize them so that editing, sharing, and organizing files become more manageable. You can also learn how to check your PDF size and how to prevent it from enlarging in the first place.

PDFs containing high-resolution images, such as catalogs and brochures, are larger in size because images bring more pixel data into the files.

Embedded fonts, multimedia, metadata, and complex design elements, such as gradients and shadows, can also inflate a PDF’s size.

You can check a file’s size on Windows by right-clicking the PDF in 

On browsers, including Chrome, Mozilla, and Safari, click 

 in the top right corner of the PDF when you open it to check how large it is.

You can reduce a large PDF size by compressing it, removing unused objects and metadata, optimizing images and converting scans, and flattening the document before exporting it.

6 Common Reasons Why PDF Files Become Large

Higher-resolution images contain more pixels

Even if you shrink the image on the page, the PDF holds the full-resolution version in the background. Therefore, the more high-resolution images a PDF contains, 

, so the document doesn't have to rely on system fonts and can still display text consistently across devices. They increase the file size because each font includes its own formatting data for every character, not just the ones used in the document. If your PDF has multiple fonts, its file size becomes even larger.

saved as images rather than text-based files

; each page is an image, with pixel data that takes up more space than text. As such, a single scanned page can make the PDF file too big.

Moreover, unlike text-based PDFs, such files don’t use efficient 

, so they can’t reduce size in the same way. As more pages are added, the PDF grows quickly because each page contributes an image.

background information stored within a PDF,

 such as author details, document properties, comments, and hidden elements. This data does not appear in the main content but remains part of the file.

the PDF continues to store this extra information

 even after edits or revisions. Over time, repeated changes can add layers of unused or outdated data. Some files may also include embedded thumbnails or attachments that are no longer needed.

Complex design elements include features such as layers, transparency effects, 

, gradients, and shadows. These elements improve visual appearance, but the PDF must

 store detailed instructions for rendering

For example, layered designs keep multiple objects and their relationships, while effects like gradients require additional data to display correctly. Unlike text, these

, audio files, and file attachments stored directly inside a document. They 

increase the amount of data the file contains

 and thereby inflate the size of the PDF.

Even short audio clips require significant storage, and attachments such as spreadsheets or documents also add their full file size to the PDF. As a result, a single embedded file can

; the file size appears near the top of the information panel.

You can also check the file size before opening a PDF. In both Windows and Mac, switching to list view in your file manager displays file sizes alongside file names. This makes it easier to compare multiple PDFs at once.

On your browser, open the PDF in a new tab, and click 

in the top right corner. The pop-up panel should tell you the file size.

Below are four ways to reduce a PDF’s size:

Compression reduces PDF file size by lowering the amount of data the file stores. It typically targets large elements like images, fonts, and embedded objects, and applies more efficient encoding. You can do it online using

To compress a PDF on Mac, follow these steps:

Removing unused objects and metadata reduces PDF file size by 

eliminating data the document no longer needs

. This includes elements like edit history, comments, hidden layers, embedded thumbnails, and unused objects left behind after revisions.

use a PDF editor’s built-in optimization features

. These scan the file and remove unnecessary data in one step. Many tools also include settings to reduce background data without affecting the content.

 to match what you will use the images for (e.g., screen viewing instead of printing)

 to limit how much pixel data the PDF stores

 to more efficient formats like JPG for photos

For scanned PDFs, converting images into text using OCR makes a significant difference. Instead of storing each page as a full image, the PDF stores actual text data, which takes up far less space.

Many PDFs contain layers, annotations, form fields, and interactive elements that require extra data to define and display. When you flatten a PDF, you

Keep these PDF optimization tips in mind to prevent large files:

You should use just one or two font families and avoid unnecessary weights or styles; this keeps the amount of embedded font data low.

 Save photos as JPG before inserting them, and avoid using PNG unless you need transparency. This reduces how much data each image adds. Use our 

Create PDFs from source files, not scans. 

You should export directly from Word, PowerPoint, or design tools instead of scanning printed documents. If you must scan, enable OCR during the process.

 To stop extra data from carrying over, it is best to remove comments, hidden layers, and unused elements in your PDF editor before exporting.

Once editing is complete, flatten layers and interactive elements. This simplifies the file and reduces stored complexity.

Large PDFs are difficult to download, upload, load, and share. Knowing why they are inflated in size can help you manage them more proactively; for example, you can take specific steps, such as optimizing images earlier in the PDF editing stage or flattening them before export. Use tools like pdf.net along the way to save time and frustration!

or contains elements that are harder to optimize

, such as embedded fonts. Some tools also apply light compression by default, which limits how much the file size decreases.

#2. Will compressing a PDF reduce its quality?

. Most tools lower image resolution or apply lossy compression, which may slightly affect visuals. However, with balanced settings, you can reduce file size while keeping text sharp.

#3. How can I check what’s taking up space in my PDF?

You can check what is taking up space in your PDF by

Many systems use a browser or built-in app, which may not always include the tools you need for editing, reviewing, or organizing documents. Knowing how to change the default viewer can help you use your PDFs more efficiently. Follow along as we break down the steps to update on Windows, Mac, and common web browsers.

A default PDF viewer is the app your operating system automatically uses to open this type of file; it can be a web browser, a built-in system app, or third-party software.

Many viewers only support basic reading, so switching to another program can give you access to more features, including editing, filling forms, applying signatures, etc.

You can update the default viewer through the
