What you get — and what changes

  • Pagination Changed

    FB2 is structured XML without fixed pages, so our ebook engine created page breaks during PDF rendering.

  • Book title Kept

    The Open Boat title appeared in converted outputs and PDF title metadata markers were present.

  • Author Changed

    Author metadata is read by our ebook engine, but PDF readers expose it differently from FB2 title-info fields.

  • Sections Kept

    The short section structure rendered as ordered prose in the PDF pages.

  • Reflow Lost

    The resulting PDF no longer adapts like an ebook; text size and line breaks are baked into pages.

  • Images Changed

    Image-bearing FB2 content can render into PDF pages, but assets are no longer separately addressable.

Options and when to change them

paper_size
Use a4 unless the PDF will be printed or reviewed in a Letter-page workflow.

Do it yourself

bash

Review page breaks because FictionBook sections have no fixed pagination before conversion.

FictionBook FB2 to PDF by API or MCP

The HTTP API and the MCP server run the exact engine this page uses (Ebook engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=fb2&to=pdf.

curl
curl -X POST https://filetypeconverters.com/api/v1/convert \
  -H "Authorization: Bearer $FTC_API_KEY" \
  -F "file=@input.fb2" -F "from=fb2" -F "to=pdf" \
  --output output.pdf
API reference

When this is the wrong conversion

  • Use /convert/fb2-to-epub if the reader should still change font size and reflow text.
  • Use /convert/fb2-to-md when the goal is text cleanup before republishing.
  • Do not use PDF as an editing source if the original FB2 XML still exists.

FictionBook FB2 to PDF questions

How many pages will an FB2 become?

It depends on our ebook engine's page layout choices and the selected paper size. Our small FictionBook sample became a 3 page PDF despite being only 549 bytes.

Does FB2 to PDF keep reflowable reading?

No. PDF fixes the text into pages, so reader font changes and ebook reflow are gone after conversion.

Is this the same as FB2 to HTML then print?

No. The service sends FB2 directly to our ebook engine for PDF output, which means our ebook engine controls the ebook interpretation and pagination.
