EPUB is the standard ebook format. Its text reflows to fit whatever screen it is on, which is perfect for an ereader and awkward almost everywhere else: you cannot print it nicely, many work and school systems do not open it, and page references change every time the font size does. A PDF fixes the text onto pages that look the same on every device and printer.
This converter checks your EPUB for DRM in your browser, then lays the book out as a PDF on our server using Calibre, the open-source ebook toolkit. Here is how it works, why some ebooks cannot be converted, what the PDF will and will not look like, and when you are better off keeping the EPUB.
How to convert EPUB to PDF
- Drop the .epub file onto the box, or click to choose it.
- Read the check under the file name. No DRM means the file can be converted. DRM means the ebook is copy protected, and the Convert button stays off.
- Click Convert to PDF. The progress bar shows the upload, your place in line and the conversion.
- The PDF downloads on its own. If your browser blocks it, click Download PDF.
- Flip through it: check the first chapter, a page with an image, any table and the last page.
DRM: which ebooks can be converted
Many ebooks you buy or borrow are locked with DRM (digital rights management), which ties the book to one app or account. Converting a protected ebook would mean removing that lock, which this tool does not do, and which is against the store terms and, in many countries, the law. The check runs in your browser before anything is uploaded, so you know right away.
| Where the ebook came from | Usually | Can it be converted? |
|---|---|---|
| Project Gutenberg, Standard Ebooks and other public domain libraries | DRM-free | Yes |
| Books you wrote and exported yourself | DRM-free | Yes |
| Many indie authors and small publishers selling direct | Often DRM-free | Yes, if the check says No DRM |
| Kobo, Google Play Books downloads, many ebook stores | Adobe DRM, unless the publisher chose DRM-free | Only DRM-free copies |
| Library loans (Libby, OverDrive and similar) | DRM-protected loans | No |
| Apple Books purchases | Apple FairPlay DRM | No |
| Kindle store books | Amazon's own format and DRM, not EPUB | No |
A common surprise: some stores give you a small .acsm file instead of the book. That is a license ticket for Adobe Digital Editions, not the ebook itself, and it cannot be converted by any tool. Open it in Adobe Digital Editions to download the protected book for reading.
What the PDF looks like
An EPUB has no fixed pages, so the converter has to decide where every page breaks. It flows the text onto standard pages with margins, keeping chapters, headings, bold and italic text, images and the reading order. Some things work differently than in an ebook app:
| In the EPUB | In the PDF |
|---|---|
| Text reflows to any screen and font size | Fixed pages; zoom in rather than reflow on a small screen |
| Page numbers depend on your reading app | Fixed page numbers that will not match the app's locations |
| Your chosen reading font | The book's own fonts, or similar ones if the book does not embed them |
| Night mode and sepia themes | Black text on white pages |
| Wide tables scroll sideways | Wide tables may be shrunk or cut at the page edge |
| Audio, video and interactive parts | Not included; a PDF page is static |
Fixed-layout EPUBs, such as illustrated children's books, comics and cookbooks designed page by page, are already built from pages. They tend to convert closer to the original, but complex layouts can still shift, so check a few spreads.
When to keep the EPUB instead
Converting is not always the best move. The PDF is a better fit for printing and fixed references; the EPUB is better for reading on small screens.
Reading on a Kindle
Kindles do open PDFs, but a full-size PDF page on a six or seven inch screen means tiny text or constant zooming. The better route is to send the EPUB itself with Amazon's Send to Kindle (the app, the web page or email). As of October 2026, Send to Kindle accepts DRM-free EPUB files and converts them into a Kindle book that reflows properly on the device. Kindles do not open EPUB files copied over USB, so Send to Kindle is the way to do it.
Reading on a phone, tablet or computer
EPUB readers are free on every platform: Apple Books on iPhone, iPad and Mac, Google Play Books (you can upload your own EPUB files), the Kobo apps, and Thorium Reader or Calibre's viewer on Windows, Mac and Linux. They keep the reflow, adjustable fonts and night mode that a PDF loses. On Windows, note that the current Microsoft Edge no longer opens EPUB files the way the old Edge did, so install one of these readers instead of looking for a browser setting.
When the PDF wins
- Printing: print a chapter, a recipe or a whole public domain book on paper.
- School and work: learning platforms, email attachments and shared drives open PDFs everywhere, and page numbers stay put for citations.
- Annotating: PDF apps and tablets with a pen are made for marking up fixed pages.
- Sharing a public domain or self-written book with someone who has no ebook app.
- Accessibility needs that a printout serves better: some readers simply prefer large-print paper, and a PDF lets you print at whatever size and spacing suits them.
Students: page numbers and citations
A PDF gives you stable page numbers to scribble notes against, which is one of the main reasons students convert ebooks. Be careful with citations, though. The page numbers in your converted PDF are not the page numbers of the printed edition; they depend on how the converter laid out the text. If your teacher or style guide asks for page numbers, use the printed edition's numbers, which some EPUBs include as hidden page markers that reading apps can show. Otherwise, the usual approach for ebooks is to cite the chapter or section heading instead of a page, so anyone with any edition can find the passage.
For your own notes, the converted PDF is ideal: highlight in any PDF app, add comments in the margins, and search the whole book with Ctrl+F.
Check the PDF before you print it
Ebooks vary a lot in how carefully they were made. Before you print 300 pages, look at:
- The first pages: cover, title page and table of contents in the right order.
- Images: sharp, not cut off at the page edge. Ebook images are sized for screens, so a small one can look soft on paper.
- Tables and code: wide content is where page layout struggles most.
- Special characters: accented letters, symbols and non-Latin scripts. Missing characters appear as empty boxes when a font lacks them.
- The page count: if a 200 page novel became 900 pages, the book probably sets a very large font size; if it became 60, a tiny one.
To print only part of the book, cut the PDF first with Split PDF or Extract PDF Pages, and if the file is large to email, Compress PDF shrinks the images.
Tip: Print two pages per sheet in your printer settings for novels. Ebook pages converted to PDF usually have generous margins, and two-up printing halves the paper without making the text hard to read. Printed double-sided as well, a 300 page PDF fits on 75 sheets.
Example: printing a classic for a reading group
A reading group wants paper copies of a public domain novel. One member downloads the EPUB from Standard Ebooks, which publishes carefully edited, DRM-free editions.
- Drop the EPUB into the box. The check shows No DRM and the number of content files.
- Click Convert to PDF and wait for the download.
- Open the PDF and check the title page, the contents and a chapter opening.
- Print one copy two pages per sheet, double-sided, and see how it reads before printing the rest.
- Share the PDF with members who prefer to read on a laptop, and the original EPUB with those who have an ereader.
Other ebook formats
| Format | Used by | Accepted here |
|---|---|---|
| EPUB 2 and EPUB 3 | Almost every store and reader except Kindle devices | Yes, when DRM-free |
| KEPUB (.kepub.epub) | Kobo's enhanced EPUB | Yes, it is an EPUB with extra markup |
| MOBI and AZW3 | Older Kindle formats | No |
| KFX and AZW | Current Kindle store books, with DRM | No |
| ACSM | A license ticket for Adobe Digital Editions, not a book | No |
Troubleshooting
- "DRM" or "encrypted content": the book is protected. Read it in the app it came from. If you bought it from an author directly and expected a DRM-free file, ask them for one.
- "Does not open like a normal EPUB": an EPUB is a ZIP package inside. A half-finished download or a file renamed from something else fails this check. Download it again.
- Empty boxes instead of letters: the book uses characters that its fonts do not include, and the replacement font lacks them too. This is most common with rare scripts and symbols.
- Huge or tiny text: the book's own style sheet sets the font size. The PDF follows it.
- "Not available yet": the ebook converter on our server is being installed or updated. Try again later.
Going the other way
If you have a PDF you want to read comfortably on an ereader, the PDF to EPUB converter turns its text into a reflowable ebook. That direction is harder, because a PDF has no idea which line belongs to which paragraph, so it works best for simple text documents.
Writing your own ebooks
If you self-publish, EPUB is the format stores want, and a PDF copy is handy as a print proof, a lead magnet or a review copy. Converting your own EPUB here is a quick way to see how the book reads on fixed pages. Picking the subject is the bigger decision: AM Jarvis Winning Niche Finder scores niche ideas on demand, competition and earning potential, which works for ebook topics as well as websites.
What happens to your ebook
The DRM check runs in your browser and uploads nothing. If the ebook is DRM-free and you click Convert, it is sent over HTTPS to our server, converted, and deleted: the EPUB as soon as the job ends, the PDF 30 minutes after it is ready. There is a daily number of free conversions and a maximum file size, both shown on the tool. The conversion uses an optional component on our server; if it is being installed or updated, the tool tells you and asks you to try again later.
