Converting PPM to AVIF produces the smallest possible modern image files from raw RGB source. Ideal for modernizing PPM archives or scientific pipeline output for efficient distribution.

Encoding is slow; expect seconds per image. Lossless AVIF preserves exact pixels; lossy AVIF at high quality is visually indistinguishable. 10–12 bit AVIF output can preserve more precision than 8-bit formats.
AVIF works in Chrome 85+, Firefox 93+, Safari 16+, modern Edge, macOS, iOS.
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.
AVIF is an image format built on the AV1 video codec, standardized in 2019. It supports HDR, wide color gamut, 12-bit depth, alpha, and animation. At matched perceived quality it's typically 50% the size of JPG and 20% smaller than WebP. Support is near-universal in modern browsers but spottier in image editors.
Lossless for quantitative or scientific use where pixel values matter. Lossy at high quality for visual presentation where size matters more than exact pixels.
Typically 10–100× smaller than PPM depending on content and quality settings.

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.
