Converting BMP to PPM produces an uncompressed RGB dump for academic or scientific pipelines that use Netpbm formats. Both formats are uncompressed, so the conversion is effectively a container swap.

Lossless for RGB channels. Alpha is stripped (PPM stores only RGB). File size is similar to BMP since neither compresses. The conversion exists mainly for pipeline compatibility.
PPM is handled by Netpbm tools, ImageMagick, and GIMP. Not a consumer format.
BMP is the uncompressed Windows bitmap format from 1990. Files are huge because almost nothing is compressed, but the format is trivial to decode and supported by virtually every Windows utility, embedded system, and legacy tool. Useful as an interchange format when other options fail.
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 is RGB only. Transparent BMP pixels become opaque RGB during conversion.
Roughly equivalent. Both are uncompressed. PPM skips BMP's header complexity but stores the same raw pixel data.

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.
