Convert cbt to jpg
Converted on your device. Files never leave this tab.
Nothing is uploaded
The converter runs inside this page. Cut your network after it loads and it still works.
No account, no daily limit
No sign-up, no daily limit, no watermark, no queue behind other people's files. Batch as many CBT files as you like.
Real JPG output
PDFs read by PDF.js, the engine inside Firefox, and comics unpacked page by page — not a renamed extension.
About CBT
Comic Book TAR
The same idea as CBZ, packed as a TAR archive instead of ZIP, with page images in filename order. Convert CBT to CBZ for comic readers that do not open TAR archives.
About JPG
JPEG (Joint Photographic Experts Group)
A lossy image format standardized in 1992 that shrinks photos by discarding detail the eye is less likely to notice. It has no transparency, and each re-save loses a little more quality. Use it for photos you want to share or upload, since nearly every device, browser and app opens it.
