How to open a .cb7 file
Quick, free ways to open CB7 on any system.
A .cb7 file is a Comic Book 7z Archive. If double-clicking does nothing, your computer simply does not have an app that reads CB7 yet. Here is how to fix that on each operating system, using free software wherever possible.
Open a .cb7 file step by step
- Confirm the file really is a .cb7. Drop it into the WhatFileType file identifier, which reads its signature without uploading anything.
- On Windows, open it with YACReader or CDisplayEx.
- On Mac, use YACReader or The Unarchiver.
- On Linux, try YACReader or MComix.
- Still stuck? Convert the .cb7 to cbz, which opens more widely.

Frequently asked questions
Why can't I open my .cb7 file?
Almost always because no installed app understands CB7. Install one of the apps above, or convert the file to a format your existing software already reads.
How do I open a .cb7 file?
Use a comic reader like YACReader, or rename it to .7z and extract the images with 7-Zip.
Why use CB7 instead of CBZ?
7z compresses more than ZIP, so CB7 files are smaller. The trade-off is that fewer readers support 7z than ZIP-based CBZ.
