Convert cbt to png
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 PNG 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 PNG
Portable Network Graphics
A lossless raster format published in 1996 as a patent-free replacement for GIF. It compresses with DEFLATE and supports full alpha transparency. Use it for screenshots, logos and graphics with sharp edges or text, where JPG compression would leave visible artifacts.
