Why convert ICO to PPM?
ICO is the Windows icon container that bundles one or more small images used for favicons and application icons. PPM is a minimal, uncompressed Netpbm format that stores raw RGB values behind a tiny text header, easy for programs to read and write.
PPM does not support transparency, so any transparent areas in your ICO are flattened onto a solid white background. PPM is lossless, so quality is preserved perfectly; expect the file to be larger than a compressed ICO.
Pixohub converts ICO to PPM entirely inside your browser using the HTML canvas API, so your images are never uploaded to a server. That makes conversion instant, completely private, and free — turn as many ICO files into PPM as you like. Reach for PPM whenever you need programming, image-processing pipelines, and academic use.
ICO vs PPM: what to expect
ICO is best for favicons and Windows desktop icons, while PPM shines for programming, image-processing pipelines, and academic use. Keep your original ICO if you may later need its transparency, and export a PPM copy for compatibility and editing.
