EPUB vs PDF: Side-by-Side Comparison
To better understand the differences between EPUB and PDF, we’ve created a side-by-side comparison table that highlights the key features of each format.
Features | EPUB | |
---|---|---|
File size | EPUB files are generally smaller than PDF files, making them easier to download and store on devices with a limited storage capacity | PDF files are typically larger in size, which can be a drawback for those with limited storage capacity on their devices |
Layout | EPUB files are designed to reflow text, meaning that the text will adjust to fit the size of the screen on the device (this makes them ideal for reading on different devices with varying screen sizes) | PDF files are designed to maintain their fixed layout, which means that the text and images will appear exactly as they were designed to appear, regardless of the size of the screen on the device |
Interactivity | EPUB files support interactive features, such as clickable links, audio, and video, making them more engaging and interactive for readers | PDF files have limited interactivity features and do not support audio and video, which can make them less engaging and interactive for readers |
Accessibility | EPUB files are designed to be accessible to readers with disabilities, such as those with visual impairments; they can be read using text-to-speech software and can be easily enlarged or customized to suit the reader’s needs | PDF files are not designed with accessibility in mind, and can be challenging for readers with disabilities to access and read |
Compatibility | EPUB files are compatible with a wide range of e-readers and devices, including smartphones, tablets, and e-readers | PDF files are also compatible with a wide range of devices, but may require additional software to be installed in order to be viewed properly |
Key Takeaways
Both EPUB and PDF have their own unique advantages and disadvantages, and the choice between them ultimately depends on the reader’s needs and preferences. EPUB is a more versatile and accessible format, while PDF is better suited for maintaining fixed layouts and design elements. By comparing the key features of each format, you can make an informed decision on which one to use for your reading needs.
EPUB vs PDF: What’s the Difference?
EPUB and PDF are two popular file formats for electronic books, but they differ in their design and functionality. In this section, we’ll compare the major differences and features between EPUB and PDF to help you decide which format is right for you.
Design and Layout
One of the key differences between EPUB and PDF is their design and layout. EPUB files are designed to reflow text, which means that the text will adjust to fit the size of the screen on the device. This makes them ideal for reading on different devices with varying screen sizes, as the text is easy to resize to fit the reader’s preferences.
In contrast, PDF files are designed to maintain their fixed layout, which means that the text and images will appear exactly as they were designed to appear, regardless of the size of the screen on the device. This can be an advantage for PDF files when it comes to preserving the original formatting and design of a document, but it can also make them less adaptable to different devices and screen sizes.
Interactivity and Multimedia Support
Another key difference between EPUB and PDF is their support for interactivity and multimedia features. EPUB files support interactive features, such as clickable links, audio, and video, making them more engaging and interactive for readers.

This can be particularly useful for educational materials, where multimedia content can enhance the learning experience. PDF files, on the other hand, have limited interactivity features and do not support audio and video, which can make them less engaging and interactive for readers.
Accessibility
Accessibility is another important factor to consider when comparing EPUB and PDF. EPUB files are designed to be accessible to readers with disabilities, such as those with visual impairments. Users can read their content using text-to-speech software.
Additionally, users can easily enlarge or customize the content to suit their personal needs. In contrast, the design of PDF files does not take accessibility into account, and readers with disabilities may find them more challenging to access and read.
Compatibility
Compatibility is also a major consideration when choosing between EPUB and PDF. EPUB files are compatible with a wide range of e-readers and devices, including smartphones, tablets, and e-readers.
This makes them a versatile choice for readers who want to access their books across different devices. PDF files are also compatible with a wide range of devices, but may require additional software to be installed in order to be viewed properly.
File Size
EPUB files tend to be smaller in size compared to PDF files. This is because EPUB files are designed to store only the text and formatting information, whereas PDF files include images and other media files. This can make EPUB files easier to share and download, particularly on devices with limited storage capacity.
Editing and Conversion
PDF files are often used for sharing documents that need to be printed or viewed as a fixed layout, and they are not easy to edit or convert. In contrast, users can easily edit EPUB files using software such as Adobe InDesign or Sigil, and can also convert them into other file formats like MOBI or AZW3. This makes EPUB files a better choice if you plan to make changes to your document or convert it to other formats.
Security
PDF files have more advanced security features compared to EPUB files. PDF files can be encrypted and password-protected to prevent unauthorized access or modifications, making them a preferred choice for documents that contain sensitive information. EPUB files, on the other hand, do not have built-in security features, and additional measures need to be taken to secure them.
Typography
EPUB files have a wider range of typography options compared to PDF files. EPUB files can use custom fonts and offer more flexibility in terms of font size, line spacing, and margins.

PDF files, on the other hand, have limits in terms of typography options and require users to have the same fonts installed on their devices to view the document as intended.
Overall, both EPUB and PDF have their unique strengths and weaknesses, and the choice between them largely depends on the intended use of the document.
If you want to create an interactive and engaging document with multimedia elements, EPUB is the way to go. If you need to share a document with a fixed layout or one that contains sensitive information, then PDF is the better option.
