Can I send the EPUB to my Kindle?

Yes. Amazon's Send to Kindle accepts EPUB files: email it to your Kindle address or upload it at amazon.com/sendtokindle and it appears in your Kindle library. Kobo, Apple Books and most other e-readers open EPUB directly.

No. The PDF is read with pdf.js and the EPUB is assembled with JSZip, both inside your browser. The file never leaves your device.

Does it work with scanned PDFs?

Not on its own. A scanned PDF is pictures of pages with no text layer, so there is no text to reflow. The tool detects this and points you to the OCR tool, which reads the text from the page images.

Is this PDF to EPUB really free?

Yes, completely free. No limits, no login, no credit card — ever.

Is there a file size limit?

No file size limits. The only constraint is your browser's available memory.

Does it work on mobile?

Yes — fully tested on iOS and Android in all modern browsers.

Do you store my files?

Never. We cannot see your files. They stay on your device the entire time.

How It Works

A PDF is a fixed page: on a phone or an e-reader it is shrunk to fit and has to be zoomed and panned. This turns a text-based PDF into a reflowable EPUB 3 in your browser, rebuilding paragraphs and chapters from the page layout so the text wraps to any screen.

1
pdf.js reads the text and where it sits
Each page's text runs are extracted with pdfjs-dist along with their coordinates and font size, and grouped into lines. A PDF whose pages have no text layer (a scan) is detected and pointed to OCR instead.
2
Page furniture is removed
Text that repeats at the same height at the top or bottom of many pages — running headers and footers — is dropped, and so are bare page numbers.
3
Paragraphs and chapters are rebuilt
Lines are joined into paragraphs using line spacing, first-line indents and sentence endings, and words hyphenated at a line end are rejoined. Lines set clearly larger than the body text become headings; the largest recurring heading size starts each chapter.
4
The EPUB is packaged
JSZip writes an EPUB 3 with one XHTML file per chapter, a navigation document plus a toc.ncx for older readers, the title, author and language you set, and right-to-left page order for Arabic, Persian, Hebrew and Urdu. Images are added only if you ask.

The PDF is read and the EPUB is built entirely on your device. Nothing is uploaded — there is no server in this workflow.
