How to Add or Replace High-Resolution Book Covers in Apple Books on iPhone
Fix blurry 200px thumbnails, missing jacket art, and generic grey rectangles in your digital library in under 10 seconds.
Apple Books often displays generic beige/grey rectangles or blurry low-resolution thumbnails when users import sideloaded or older EPUB books. Traditionally, fixing missing cover art required a desktop computer, Calibre, image resizing utilities, and USB syncing. EpubTidy solves this instantly on iOS with a Smart Cover Matcher that queries the Apple Books catalog to fetch official retina-quality jacket art in seconds.

The Frustration of Blurry Covers in Modern E-Readers
Why retina displays make bad covers look terrible
Modern iPhones and iPads feature gorgeous Super Retina XDR and Liquid Retina displays with over 460 pixels per inch. When you open Apple Books and see a beloved novel represented by a blurry 150x200 pixel JPEG from 2008 or a generic title-only placeholder, it ruins the aesthetic pleasure of digital collecting.
This happens because older EPUB files were compressed for early low-memory e-ink readers. Worse, some sideloaded books lack the proper `<item id='cover-image' properties='cover-image'/>` manifest declaration, preventing Apple Books from detecting the cover even if an image exists inside the archive.
Instant High-Resolution Cover Repair with EpubTidy
Two effortless ways to beautify your library on mobile
EpubTidy provides two powerful cover repair methods directly on your iOS device:
1. **Smart Cover Matcher:** Tap 'Match Cover' and EpubTidy immediately searches the official Apple Books global catalog using the book's title and author. Within seconds, it retrieves pristine, retina-resolution official jacket art and writes it directly into the EPUB container.
2. **Custom Camera Roll:** Prefer an alternative edition, vintage illustrated artwork, or custom fan design? Pick any photo from your Photos app, crop it with the built-in aspect-ratio guide, and set it as the permanent cover.
EpubTidy automatically updates the OPF manifest, cleanses old thumbnail references, and ensures the cover displays immediately when shared back to Apple Books.

Can I use custom artwork from Pinterest or Google Images?▼
Yes. Simply save the image to your iPhone's Photos app, open the book in EpubTidy, tap Cover, and select 'Choose from Photos'.
Will the new cover be permanent when transferred to other e-readers?▼
Yes. EpubTidy embeds the new cover directly into the EPUB container file, ensuring it displays on Kobo, Boox, Kindle, and Calibre.
