Unfurl: All File Format Reader

Unfurl turns PDFs into comfortable ebooks and opens almost every document, ebook and comic on your phone. Free, offline, no ads, no account.

READ ANY PDF LIKE AN EBOOK
PDFs open exactly as designed. Tap once and Reader mode unfurls the page into flowing text that fits your screen, with your font, size, spacing and theme. Switch back anytime and you stay on the same passage. Works with EPUB, DOCX files and slides too.

SEE HOW YOU READ
Insights shows your reading time, speed, favourite reading hours, finished books and a year of reading at a glance. Every book also has its own insights. All of it stays on your phone.

BROWSE EVERY FILE, CALMLY
The Files tab is a clean, read-only explorer for your phone: Downloads, Documents, messaging app files, SD cards and more. Big folders load quickly as you scroll. Unfurl never renames, moves or deletes anything.

PRIVATE BY DESIGN
Unfurl has no internet permission, so it cannot send your files or reading data anywhere. No ads, no tracking, no account, no sign-in. Full file access is optional; without it you can still open files and add folders yourself.

BUILT FOR PHONES AND TABLETS
Material 3 Expressive design, Material You colours, and two-page spreads on tablets and in landscape.
