Comfortable reflowable reading
Adjust fonts, size, spacing, margins, and themes for a page that fits the iPhone instead of imitating a fixed sheet of paper.
EpubTidy is a focused reader for people who keep DRM-free EPUB files. Open a book from Files, tune the page for your eyes, organize the library, and carry the corrected EPUB to any compatible reading app.
EpubTidy combines comfortable EPUB reading with the tools a personal library eventually needs: metadata correction, cover replacement, formatting cleanup, library checks, offline AI read aloud, and portable export.

Adjust fonts, size, spacing, margins, and themes for a page that fits the iPhone instead of imitating a fixed sheet of paper.
Review titles, authors, covers, identifiers, series information, and possible duplicates without moving the collection to a desktop.
Imported books remain available without Wi-Fi. Reading and core EPUB management happen locally on the device.
Switch from visual reading to downloadable on-device AI voices when walking, commuting, resting, or working with your hands.
Clean common HTML, CSS, spacing, metadata, and cover problems that ordinary reader apps simply display without fixing.
Export an updated standard EPUB to Apple Books, Kindle delivery, Files, AirDrop, or another compatible reader.

Apply only the repairs you want, verify the result, and share the updated EPUB to the destination you choose.
A practical framework for comparing readers by ownership, typography, privacy, audio, organization, and export.
