Converting WebP to PPM produces an uncompressed RGB dump for academic image processing, scientific pipelines, and custom code that expects Netpbm input. Every pixel becomes three raw bytes in a format any library can parse.

PPM strips the alpha channel entirely and applies no compression, so files are enormous. Quality matches whatever the WebP decoded to; lossy WebP artifacts survive unchanged.
PPM is supported by ImageMagick, GIMP, feh, and Netpbm tools. Consumer viewers rarely handle it. Use only when a specific pipeline or course requires Netpbm format.
WebP is Google's 2010 image format based on the VP8 video codec. It offers lossy and lossless modes, full alpha transparency, and animation in a single container. At matched quality it's typically 25–35% smaller than JPG or PNG. Every major browser has supported it since 2020.
PPM is a trivially simple uncompressed RGB format from the Netpbm suite. Each pixel is three bytes, prefixed by a tiny text header. Used in academic image processing, scientific computing pipelines, Linux kernel boot splashes, and as a debug format because anyone can write a parser in 20 lines.
No. PPM stores RGB only. Transparent pixels become whatever RGB value the encoder assigns, typically black or the matte color.
Simplicity. You can write a PPM parser in 20 lines of any language. That's its entire reason to exist, not efficiency or compatibility.

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
