PDF is the universal fixed-layout document format — it renders identically across viewers, preserves fonts and formatting, and is the accepted-by-default format for invoices, contracts, government uploads, academic submissions, and portfolio work. Convert to PDF when the receiving system explicitly wants PDF or when the layout must not shift.
Freeze a reflowable book into a printable, shareable, universally-openable PDF with a consistent page layout.
Free-tier uploads are capped at 10 MB per file — enough for most novels and non-fiction. Pro handles files up to 1 GB and batch jobs of up to 20 books, which comfortably covers a whole legacy library conversion in a single session.
A4 or US Letter are the safe defaults for anything you'll print. Text size defaults to a comfortable reading value; bump it up for older eyes, or down for a denser page. The preview shows how many pages the finished PDF will be so you know what to expect before hitting Convert.
The PDF is ready in a few seconds. Chapters become bookmarks in the PDF's table of contents, cover art embeds on the first page, and inline images travel through at full resolution. Both the source and the converted PDF are permanently deleted from our servers within 30 minutes.
The trade-off is real: an FB2 is designed to reflow around whatever screen it's on. A PDF locks the page shape and text size. The PDF you get will look identical on every device — great for printing, submitting, and archiving — but you lose the "resize to fit" behaviour readers expect on phones. Pick this conversion when consistency matters more than flexibility.
Six real scenarios where the fixed-page format is exactly what you want.
Reader apps rarely offer a proper "print" function. Converting your FB2 to a PDF first gives you a predictable page layout, fits every printer's expectations, and lets you decide margins and page size in advance rather than fighting the reader's UI.
Not everyone has Kindle or Apple Books installed. Sending a PDF means the recipient can open it on any device, straight from an email attachment, without installing a specialised reader.
Ebook formats come and go — MOBI is on the way out, LIT is nearly gone, even EPUB has multiple versions. PDF has been stable for decades and will keep opening in the year 2050. Converting your library to PDF makes an archival copy that outlives any specific reader ecosystem.
Academic workflows lean on PDF annotators like Zotero, Mendeley, and PDF Expert. Highlighting, note-taking, and citation extraction are much richer in these tools than in most ebook readers. Converting to PDF unlocks the whole PDF-annotation ecosystem for the book.
Publishers, review committees, and journals often require PDF submissions. If you're distributing an FB2 you authored for review, converting to PDF produces the format the recipients actually want to read.
Print-on-demand services (Amazon KDP Paperback, IngramSpark, Lulu) require PDF interiors. Converting your finished FB2 to PDF is a standard step in the pipeline from digital-only to printed copy.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

FB2 (FictionBook 2.0) is an XML-based ebook format created in Russia that has become the dominant standard for digital books in Russia, Ukraine, and across Eastern Europe. Unlike formats that store visual presentation, FB2 uses semantic markup to describe the logical structure of a book — title pages, chapters, sections, epigraphs, poems, and citations are all encoded as distinct XML elements, making it exceptionally well-suited for fiction and literary works.
FB2 stores rich metadata including author biography, genre classification, series information, and cover images directly within the XML structure, making library management and cataloging straightforward. The format handles Cyrillic and Unicode text natively, ensuring proper rendering of Russian, Ukrainian, Bulgarian, and other scripts. FB2 is supported by popular reading apps like FBReader, CoolReader, and Moon+ Reader, particularly on Android. While less common outside Eastern Europe, FB2 files can be converted to EPUB, PDF, or MOBI for use on international eReaders and Kindle devices.
