CoverZip
Browse archives and folders comfortably from Finder
A macOS app for reading comics and image collections stored inside ZIP, CBZ, RAR, CBR archives or plain folders. It adds cover thumbnails to supported archives through a Quick Look extension, opens archives and folders with the space bar, and keeps reading smooth with spreads, reading direction options, and GPU read-ahead caching.

See it before you even open it.
From Finder Quick Look to a fast dedicated viewer, it refreshes the entire archive and folder reading flow.
Quick Look thumbnails
Automatically shows the first image in ZIP, CBZ, RAR, and CBR archives, prioritizing cover-like filenames, as the Finder icon so you can recognize the content immediately.
Quick Look viewer
Select a supported archive or image folder and press the space bar to launch the comic viewer. Page turns, spreads, and reading direction controls are available directly inside Quick Look.
Preview folders directly
There is no need to zip images first. Select an image folder in Finder to browse it with the same controls as an archive, including subfolders and natural filename sorting.
Built-in app viewer
Opens archives and folders in the built-in viewer with arrow-key navigation, 10-page jumps, and first/last page moves. A page slider and thumbnail strip let you jump directly to any page.
Routing rules
Uses filename and folder rules to decide which app should open a ZIP, CBZ, RAR, or CBR archive on double-click. Partial match, prefix match, and regular expression modes are supported.
Spread view and reading direction
Supports two-page spread composition and switching between left-bound and right-bound reading to match different comic styles.
Resume where you left off
Remembers the last page and settings for each archive or folder, keeping the latest 100 entries so you can continue reading automatically next time.
Slideshow mode
Can advance pages automatically at a configured interval, which is handy when you want hands-free reading.
GPU read-ahead cache
Uses GPU pre-rendering and read-ahead caching for smooth performance even with large archives and folders, and releases memory automatically under pressure.
