About this tool

Reading an A4 PDF on a phone means endless zooming and sideways scrolling. PDF Reflow extracts the text, rebuilds headings, paragraphs and lists, removes running headers, footers and page numbers, and lays everything out again as a narrow single-column document with the font size you choose.

Pick a page size for a phone, e-reader, tablet or A6, and get a new PDF with real, selectable text — or an EPUB e-book that adapts to any screen and works in Apple Books, Google Play Books, Kobo and Thorium. Thai text wraps at word boundaries.

Everything is done with layout heuristics right in your browser: no AI service, no upload. Images and complex tables are not carried over, so it works best for text-heavy documents such as articles, reports and books.

Frequently asked questions

Does it use AI?

No model is downloaded and nothing is sent anywhere — paragraphs and headings are reconstructed from fonts and positions.

Where are the images?

Can I send the EPUB to Kindle?
