Open and read a CBZ comic online
Open a CBZ file (comic archive in ZIP format) and read it page by page directly in your browser, without installing any software.
or click to select it
A CBZ is simply a ZIP with page images. The tool detects them, sorts them naturally (1, 2, 10 -- not 1, 10, 2) and shows them one at a time. No library, accounts, favorites or sync -- just reading.
Use cases
- Read a downloaded comic without installing a dedicated reader.
- Quickly check the contents of a CBZ before saving it.
- Read comics in your phone's browser.

Technical details
JPG, JPEG, PNG, WEBP and GIF images inside the archive are shown as pages; everything else (ComicInfo.xml, text files, __MACOSX folders or hidden files) is ignored. Sorting is natural over the full path, so per-chapter subfolders stay in order too (ch2 before ch10). Each page is fitted to 75% of the screen height and you turn pages with the Previous and Next buttons.
Files up to 50 MB are supported, with at most 2,000 entries and 300 MB uncompressed. The type is detected from the content, not the extension: a .cbz that is really a RAR opens just the same.
Frequently asked questions
Is my reading progress saved?
No, this tool doesn't keep a library or progress; each time you open the file you start from the first page.
Which image formats are supported?
JPG, PNG, WEBP and GIF -- the usual image formats inside a CBZ.
Why does it say no images were found?
Because the pages are in a format the reader doesn't display (for example AVIF, BMP or JPEG XL) or the archive contains no images. Only JPG, PNG, WEBP and GIF are read.
