CBR / CBZ Comic Reader
Open and read comic book archives right in your browser
How it works
Drop in a comic book archive — CBZ (ZIP), CBR (RAR, including RAR5), CB7 (7-Zip) or CBT (TAR), or any plain archive of images. The file is unpacked directly in your browser by libarchive compiled to WebAssembly (served from this site, not a CDN), so the comic never leaves your device. Pages are sorted in natural reading order (page 2 before page 10) and non-image entries like ComicInfo.xml or macOS metadata are skipped. Read with the arrow keys, space bar, on-page arrows, the page scrubber or the thumbnail strip; switch between fit-to-screen, fit-to-width and actual-size views; go fullscreen for a distraction-free read; and download any single page as an image. Password-protected CBZ (ZIP) archives are supported — you'll be prompted for the password, which is only used locally.
Frequently asked
Is my comic uploaded anywhere?
No. The archive is extracted entirely in your browser using libarchive compiled to WebAssembly. Pages are held in memory on your device and are gone when you close the tab.
Which formats are supported?
CBZ (ZIP), CBR (RAR 4 and RAR 5), CB7 (7-Zip) and CBT (TAR) — plus plain .zip, .rar, .7z and .tar archives of images. Pages can be JPG, PNG, GIF, WebP, AVIF or BMP.
How do I turn pages?
Use the ← and → arrow keys (or space, PageUp/PageDown, Home/End), click the on-page arrows, drag the page slider, or click a thumbnail. A fullscreen mode is one click away.
Can it open password-protected archives?
Password-protected CBZ (ZIP) archives work: you'll be asked for the password, which is used only by the local WebAssembly extractor and never transmitted. Encrypted RAR archives are not supported.
Why are pages in the wrong order?
Pages are sorted in natural order by filename (page2 before page10), the same way desktop comic readers sort them. If a comic still reads oddly, the files inside the archive are likely misnamed.
What's the difference between CBR and CBZ?
Both are ordinary archives of images renamed with a comic extension: CBZ is a ZIP file, CBR is a RAR file (CB7 is 7-Zip, CBT is TAR). This reader opens all of them the same way.
