Merge eBooks to PDF: Combine EPUB and FB2 Books into One File

When several ebooks belong together, one PDF is easier to read, print and share than a folder of separate files. PDF-File.com's Merge eBooks to PDF tool turns EPUB and FB2 books into one PDF in the order you add them, and you don't need desktop software or an account.

The books get typeset again as plain text pages, so what you download reads like a clean printout, not a copy of your ebook app's layout. Flip through the first pages of each book in the download before you share it.

How to merge ebooks to PDF

1. Click the upload area and select two or more EPUB or FB2 files, or drag them onto the page.
2. Click + to add more books, or remove a file you picked by mistake.
3. Check the order: the books show up in the PDF in the order you added them.
4. Click Merge to PDF and wait while the server converts each book.
5. Download the merged PDF once processing finishes.

You can't drag books into a new order, so add them in reading order from the start. If the order is wrong, click Delete All and select the files again, starting with the first book.

Which ebook formats can you merge?

The tool takes EPUB and FB2 files of up to 25 MB each, and you can mix both formats in one PDF. EPUB is the W3C format for digital publications, and FB2 (FictionBook) is an XML-based ebook format.

Kindle formats such as MOBI and AZW won't go in, and the tool doesn't remove DRM. The server also checks that an EPUB starts like a ZIP archive and an FB2 file like XML, so most renamed files get turned away early.

How the merged PDF is built

Our server converts each book on its own with pandoc, which reads EPUB and FictionBook2, and typesets it with XeLaTeX, one-inch margins and the DejaVu Sans font. Then qpdf joins the separate PDFs in your upload order.

Since every book is converted separately, each one starts on a new page and keeps its own page numbers, beginning at 1. The ebook's original fonts, colors and page styling don't carry over.

DejaVu Sans covers Latin, Greek, Cyrillic, Arabic and Hebrew text. A book that needs characters the font doesn't have, such as Chinese, Japanese or Korean, fails instead of handing you a PDF with missing letters.

Bookmarks and page numbers in the merged PDF

The merged PDF has no bookmarks, so the bookmark panel can't take you from one book to the next. In October 2026 we built two EPUBs of three chapters each: converted alone with EPUB to PDF, each gave 3 bookmarks, yet their merged 4-page PDF had none, because qpdf joins the pages and leaves the outlines behind.

Page numbers restart in every book, so the footers of that merge read 1, 2, then 1, 2 again. Jot down the page where each book starts, or keep the books as separate PDFs if your readers need to jump between chapters.

Long books merge fast. Three copies of a 48,000-word test book became one 201-page PDF of 455 KB, ready 4.9 seconds after the upload on our test server.

What happened when we tested Merge eBooks to PDF

We uploaded our small test book sample.epub (2.4 KB) twice and merged the two copies in upload order. The result, sample_MergedEbook.pdf, was 18.8 KB and 2 pages: one page per copy, each with the book's title, its author line and its text. Tested in October 2026.

Each copy starts on its own page because the books are converted one at a time and then joined.

Why combine ebooks into one PDF?

Maybe you're a student joining a textbook with its workbook and your reading notes, or an author putting a manuscript and its appendices together. Either way, readers open one file and move through the collection in a fixed order.

PDF opens on almost any phone, tablet or computer and keeps the same page layout everywhere, which helps when you print or archive. Do make sure you have the right to combine and share the books, especially ones under copyright or a publisher's license.

For a single book, our EPUB to PDF converter and FB2 to PDF converter do the same conversion without the merge step. Already have PDFs you want joined? Use Merge PDF.

Tips for a better merged PDF

Put the books in reading order

Add introductory material first and appendices last. A number prefix on each file name, such as 01-introduction.epub and 02-volume-one.epub, makes the right order easy to pick in the file dialog.

Keep the output manageable

Books with lots of images can add up to a big PDF. Our Compress PDF tool can shrink the result, and our tools for splitting and organizing PDFs can break a very large collection back into smaller files.

Review the result before sharing

Skim the start of each book and the last pages of the file. Make sure every title made it in and that tables or images came through the way you need them.

Frequently Asked Questions about Merging eBooks to PDF

Can I merge EPUB and FB2 files together?

Yes. One PDF can mix EPUB and FB2 books, and they show up in the order you uploaded them.

Can I change the order after uploading?

Not by dragging. Click Delete All and add the files again in the order you want.

Will the PDF look like my ebook reader?

No. Each book gets typeset again as plain text pages with one-inch margins, so the ebook's own fonts and styling don't survive.

Can I merge Kindle books?

No. It only takes EPUB and FB2 files, and it doesn't remove DRM from books you bought.

How large can each ebook be?

Up to 25 MB per file. We delete the uploads and the merged PDF from our server automatically within two hours.

Is it legal to merge ebooks?

Merging files for personal use doesn't remove copyright or license terms. Only process and share ebooks you have the rights or permission to share.
