About CB7
A CB7 is a 7z archive of pictures, one per page, read in the order of their names, named like CBZ and CBR so comic readers know it. 7-Zip packs it a little smaller than ZIP or RAR, though pictures barely shrink.
Fewer apps read CB7 than CBZ or CBR, and no phone or browser opens 7z by itself, so a CB7 usually needs a comic reader on a computer.
Filepeek unpacks it with 7-Zip as you read, solid archives in one pass, and shows it a page or two at a time, right to left for manga. Save as CBZ turns it into the comic format every reader opens.

Questions
How do I open a CB7 file?
Drop it on this page or choose Peek a CB7. It opens at its first page, with no 7-Zip or comic app to install.
Can I turn it into a CBZ?
Yes. Choose Export, then Save as CBZ, and its pages and details go into a ZIP that every comic reader and e-reader opens.
Can I read manga right to left?
Yes. Choose Right to left, and the pages and spreads read the way manga does. A comic whose ComicInfo.xml says to read it right to left opens that way by itself.
Can it open a CB7 with a password?
Yes. Type the password when Filepeek asks, and it opens. The password stays on your device, and it's gone once you close the file.
Is my file uploaded?
No. The comic opens inside your browser and never leaves your device.
