Convert PDF to EPUB
Turn your PDF into EPUB in seconds. Browser-based, no install.
- Browser-based — no install
- Files private to your account
- Up to 250 MB on Pro
Drop in your EPUB file
Or upload any PDF, Word, Excel, PowerPoint, JPG, or PNG — we'll convert it to EPUB either way.
Supported: PDF · DOCX / DOC · XLSX / XLS · PPTX / PPT · JPG / JPEG · PNG
Turn a PDF into a reflowable EPUB e-book. Unlike a PDF — which keeps a fixed page size and font — an EPUB adapts to whatever device you're reading on. Bigger font on your phone, dark mode at night, no pinch-zooming to read.
How it works
Right in your browser, no install
Flint PDF runs entirely in your browser. Drop a file in, do the thing, get the file out.
- 1
Upload the PDF
Drop in a text-heavy PDF (an article, a paper, a book) you'd like to read more comfortably.
- 2
We reflow the text
Headings, paragraphs, and images are rebuilt into an EPUB so text wraps to fit any screen.
- 3
Read on any device
Open the .epub in Apple Books, Kindle (via Send to Kindle), Calibre, Kobo, or any modern e-reader app.
What it's for
Built for real work
Long-form articles & papers
Read a 30-page PDF without zooming and squinting on a phone screen.
Books and manuals
Turn product manuals, technical books, or reports into something you can actually read in bed.
Adjustable accessibility
Bigger font, more line spacing, dark mode — all the e-reader controls that PDFs can't give you.
FAQ
Frequently asked questions
- Does it work for any PDF?
- Text-heavy PDFs work best — articles, papers, novels. PDFs that are mostly layout-driven (magazines, brochures) reflow less cleanly because their visual design depends on the page size.
- Will images be included?
- Yes. Inline images stay in the EPUB and reflow alongside the text.
- Is it free?
- Preview is free; downloading the .epub requires Flint Pro.
- Are my files private?
- Yes — processed only for your conversion, never shared.
- What's the max file size?
- PDFs up to 250 MB on Pro.
- Can I send the EPUB to a Kindle?
- Yes — Amazon's Send to Kindle accepts EPUB files now. Email the .epub to your Kindle's send-to-Kindle address or use the Send to Kindle app.
