Converting PPM to JPG shrinks uncompressed academic or scientific image data into a shareable format. Useful when research output or computer-vision pipeline results need to be sent, documented, or published in a format non-technical recipients can open.

Lossy compression is introduced. For photographic content at quality 85+ the difference is invisible. For synthetic images (renders, visualizations), JPG's compression can introduce artifacts that matter in research contexts.
JPG runs on every platform ever.
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.
JPG (JPEG) is a 1992 lossy photo format that became the default way to store photographs on the web. It uses a discrete cosine transform plus quantization, tuned so that errors fall where human vision is least sensitive. No transparency, no animation, but excellent for photos at 70–90% quality.
Yes, through lossy compression. For qualitative viewing this is fine; for quantitative analysis use PNG or keep the PPM.
For photographic content, often 50–200× smaller than PPM at quality 85 with no visible difference.

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.
