PDF to EPUB

A PDF is made of fixed pages. On a 6-inch e-reader or a phone, a Letter-size page is so small you end up pinching and panning. An EPUB is reflowable: text adapts to the screen width, you pick the font size, spacing and typeface, and the reader remembers your place.

PDF to EPUB is the fix when you want to read a PDF book, paper, report or manual comfortably on a Kobo, PocketBook, Kindle or a phone app. Amazon's Send to Kindle accepts EPUB files directly.

Kitpebble does the conversion in your browser, so the PDF never leaves your device.

A PDF doesn't record where paragraphs start or what a heading is, only where each letter sits on the page. The converter rebuilds the structure:

• Lines into paragraphs, using line spacing, first-line indents and short, sentence-ending lines. A sentence split across pages is joined back up.
• Hyphenation removed: words broken at line ends are rejoined, while capitalized compounds and short abbreviations keep their hyphens. Occasionally a genuine compound that falls at a line end loses its hyphen.
• Headings detected from larger or standalone bold lines, up to four levels.
• Chapters start at the top heading level and make up the table of contents.
• Running headers, footers and page numbers repeated across pages are removed.
• Formatting: italics, bold, superscript note numbers and bullet lists are kept, and fi/fl ligatures become plain letters.

The cover is an image of the PDF's first page, which for most books is the cover itself. Switch it off if your first page is a plain title page.

Images (photos, figures, illustrations) are cropped from each page and placed where they appeared. Chart labels stay on the image instead of spilling into the text, and logos repeated on every page are skipped. Pages with no text, like a full-page map, go in as page images.

A fully scanned PDF has no text to reflow. Run OCR on it first, then convert the result.

Single-column text PDFs give the best results: novels, nonfiction, theses, papers and manuals. Harder cases:

• Multi-column magazine pages: column order is usually right, but sidebars may land mid-text.
• Tables come through as plain text without their grid.
• Vector drawings such as line art and charts aren't images, so they're left out.
• Equations keep their characters but lose fraction bars and radicals.

The result is a standard EPUB 3 with an EPUB 2 table of contents (NCX) for older readers, plus title, author, language, cover and clickable contents. When it's done you get a summary of chapters, approximate word count and images.
