How do I convert a CBR file to PPM?

Upload your CBR file (a RAR archive of comic pages) to the tool. The converter extracts each page and outputs PPM P6 files. You can download all images individually or as a ZIP. The process is completely automated and preserves original resolution.

Why would I convert CBR to PPM?

PPM is a lossless uncompressed format; it's useful for pixel-perfect image data in scientific imaging, OCR, or legacy software. Since CBR stores JPEG pages, converting to PPM avoids additional compression artifacts beyond the original, and PPM can be easily pipelined in Unix tools like ImageMagick. However, file sizes are significantly larger.

What happens to image quality and metadata during CBR to PPM conversion?

The conversion extracts the original JPEG images and decodes them to raw RGB values in PPM. Resolution and bit depth are preserved, but any JPEG artifacts are baked in. PPM does not support alpha channels, so transparency in PNG pages is lost. ICC color profiles and EXIF metadata are not retained; only raw pixel data is saved.
