Converting PPM to PNG wraps raw RGB pixel data in a lossless compressed container with universal support. This is the standard move for getting scientific or academic image output into a shareable format.

Lossless pixel preservation. File size shrinks substantially because PNG uses DEFLATE compression where PPM uses none. No alpha is added (PPM has none to carry).
PNG runs everywhere.
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.
PNG is a lossless image format designed to replace GIF. It uses DEFLATE compression, supports an 8-bit alpha channel for full transparency, and preserves every pixel exactly. PNG excels at images with sharp edges, large flat-color regions, text, UI screenshots, and anything you'll re-edit.
Typically 3–10× smaller. PPM has zero compression; PNG uses DEFLATE which handles most image content efficiently.
Yes. PNG is lossless: the pixel values in the PNG match the PPM exactly. Important for scientific and quantitative use.

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.
