    The details

    What happens when you convert a PDF to an e-book

    The portable document format. Fixed layout, universal, and the reason everyone can open the file you send them. The pages are re-flowed into a single scrolling document, with the text put back into paragraphs and the images pulled out of the page. The result is a the standard e-book format. reflowable text that fits whatever screen you are reading on, produced entirely inside your browser.

    What survives

    • The text, in a form that reflows to the screen
    • The images

    What changes

    • The fixed page layout, which is the whole point of going the other way
    • Footnotes, which usually end up as ordinary text

    Where it goes wrong

    • A two-column academic PDF often reflows into one unreadable column
    • Chapter boundaries are guessed from page headings, and are sometimes wrong

    Why anyone would do this

    Reading on a phone in the dark, with the text at the size you want.

    About the format

    The portable document format.

    A tree of objects describing pages, fonts, images and scripts, with a cross-reference table and a file trailer. Text and vector graphics are stored separately from the page layout.

    Where it is good
    • Looks identical on every operating system and every device
    • Holds text, images, vector art, forms, signatures and 3D
    • Can be locked, compressed, tagged for accessibility and archived as PDF/A
    Where it falls short
    • Not really editable — you change the source document, not the PDF
    • Fonts and complex layouts can shift when converted back to an office format
    • A file with lots of scans can be enormous
    You will find it on
    Everyone, everywhere, for everything

    The thing people miss

    PDF was invented as a screen format, not a print format — which is why the page sizes are in points, not millimetres.

    About the target

    The standard e-book format.

    A ZIP archive of XHTML documents, a stylesheet, images and a manifest that says which file is the cover and which is the table of contents.

    • Reflows to any screen, so it is comfortable on a phone
    • Fonts can be resized by the reader without breaking the layout
    • Supports images, footnotes, tables and audio

    Questions

    PDF conversion questions

    What actually happens to my PDF file when I convert it to EPUB?

    The pages are re-flowed into a single scrolling document, with the text put back into paragraphs and the images pulled out of the page. So the PDF file is unpacked, the content is laid out, and the result is written out as EPUB. The text, in a form that reflows to the screen survives unchanged.

    Will converting PDF to EPUB reduce the quality?

    Partly. Some formatting is approximated because the two formats describe layout differently. The text itself is never re-typed, so no words are lost.

    Is my PDF file uploaded to a server?

    No. This PDF to EPUB conversion runs as JavaScript inside your browser tab. The file is read from your device and the result is written back to your device, so there is no upload step, no file-size limit and no copy of your PDF file on any server.

    Do I need an account or will there be a watermark?

    Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.

    What is the most common mistake people make when converting PDF to EPUB?

    A two-column academic PDF often reflows into one unreadable column

    Why would somebody convert PDF to EPUB at all?

    Reading on a phone in the dark, with the text at the size you want. In short: sending a document that must not change on the way

    Something most people do not know about PDF?

    PDF was invented as a screen format, not a print format — which is why the page sizes are in points, not millimetres.
