Convert cbt to pdf
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 PDF 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 PDF
Portable Document Format
Adobe's fixed-layout document format from 1993, an ISO standard (ISO 32000) since 2008. It embeds fonts and images so each page looks the same on every device. Use it for documents you want to send, print or archive without the layout shifting.
