FAQ and format details
Why convert PDF to EPUB?

A textbook PDF you are allowed to repackage for personal reading, a report you want on a phone, a public-domain scan that already went through OCR. If the file is a comic or a design portfolio, stay in PDF.

How this conversion runs

pdf.js text → HTML (page sections) → EPUB. Page h2s may become too many 'chapters' if you have one h2 per PDF page — you will want to merge. There is no automatic chapter detection from 'Chapter 3' strings.

Keep in mind for PDF → EPUB

A 300-page PDF becomes a heavy HTML soup. Running headers will repeat. Hyphenation stays. DRM-encumbered PDFs should not be dropped here; encrypted files will simply error. This is not a piracy aid and it will not break DRM.

After you have a EPUB file

Open in Thorium, delete repeating headers in Sigil, merge chapters. Calibre can go to Kindle. Keep the PDF for citations and figures.

Each PDF page became a chapter. How do I fix that?

Our HTML wraps pages in h2. Convert PDF→HTML, demote those to paragraphs, add real h1s for chapters, then HTML→EPUB.

Will figures appear in the EPUB?

Not from the PDF drawing layer. You get text. Add images later in Sigil if you have rights to them.

About PDF and EPUB

Source file

PDF

A page-description format that paints glyphs and graphics onto fixed pages. Universal for print, archival, and sharing.

PDF (Portable Document Format) describes pages, not a flowing document tree. Incoming PDFs are reconstructed as HTML: designed pages keep positioned text, fonts, images, and vectors; simpler reading documents become flowing articles. Export to PDF paints HTML onto pages via pdf-lib. Pixel-perfect Word/InDesign layout is not the goal.

Read into HTML
medium fidelity · implemented — pdf.js extracts text, fonts, images, and vectors. Designed or overlapping pages stay visually positioned; simpler reading documents become flowing HTML with inferred headings, lists, and a sidebar when one exists. Scanned PDFs without a text layer will be empty.

Destination file

EPUB

The open ebook format: a ZIP of XHTML chapters, CSS, and a package manifest. What Apple Books, Google Play Books, and most non-Kindle readers consume.

EPUB 3 is HTML in a spine. That makes the HTML hub almost native: we concatenate or split XHTML documents and rewrite the OPF package. Kindle’s AZW/MOBI family is a different type and is not in this matrix.
