Why convert BMP to PPM?
BMP is an uncompressed raster format that stores raw pixel data, yielding large but universally readable files. 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 is lossless, so quality is preserved perfectly; expect the file to be larger than a compressed BMP.
Pixohub converts BMP 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 BMP files into PPM as you like. Reach for PPM whenever you need programming, image-processing pipelines, and academic use.
BMP vs PPM: what to expect
BMP is best for maximum compatibility with legacy Windows software and raw, lossless pixels, while PPM shines for programming, image-processing pipelines, and academic use. Keep your original BMP if you may later need the source file, and export a PPM copy for compatibility and editing.
