Document Converter
A document converter rewrites a file's words and structure into another document format, like PDF to DOCX or Markdown to PDF. FileFlip runs Pandoc and MuPDF in your browser, so a contract or an unpublished manuscript never touches a server.
Every one of them runs in the browser, on this page, with no upload and no account.
Popular document conversions#
Every document format FileFlip supports#
FileFlip reads 9 of these without writing them, so they work as a source and not as a target. Another 9 can be produced but not opened, so they appear as a target only.

How document conversion works here#
Pandoc is a 58.6 MB module and covers the markup and office formats: DOCX, ODT, EPUB, Markdown, LaTeX, HTML, RST and around forty others. MuPDF is 10.4 MB, reads and writes PDF and CBZ, reads MOBI and XPS, and renders a page to an image when a document has to become a picture.
A document conversion recovers content rather than layout. A PDF stores glyphs at fixed positions with no paragraphs and no headings in it, so converting one to DOCX hands back the words and an approximation of the structure. Going the other way, into PDF, is exact, because that direction only has to draw.
Every engine, its exact version and its download size are listed on how FileFlip works, along with how to check for yourself that nothing is uploaded.
