PDF (Portable Document Format) uses fixed-layout document encoding and is best for document sharing, printing, and archival with consistent formatting. EPUB (Electronic Publication) uses reflowable ebook encoding and excels at e-readers, mobile devices, and accessible digital books. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Yes — text becomes reflowable with adjustable font size, unlike fixed-layout PDF. Tables and multi-column pages are linearized; check the chapter breaks after conversion.
Images carry over at readable resolution; detected headings become a navigable table of contents. Scanned PDFs need OCR first — images of text won't reflow.
Generic EPUB works on Kobo, Nook, Apple Books, and most apps. For Kindle, prefer the MOBI/AZW3 path or email the EPUB to your Send-to-Kindle address for auto-conversion.
