Frequently asked questions

Everything you might wonder about recompressing images in Benefic.

What does the recompressor do?

It decodes your source image and re-encodes it into the format and quality you pick. JPEG output is encoded with mozjpeg, which produces noticeably smaller files than a stock encoder at the same visual quality.

Which formats can I drop?

Anything image-rs can decode in the browser: JPEG, PNG, WebP, TIFF, GIF, ICO, PNM (PBM/PGM/PPM), and BMP. The output format is independent of the input.

Does the quality slider apply to PNG / TIFF / etc.?

No. PNG, TIFF, GIF, ICO, PNM, and BMP are lossless — the quality value is ignored for those outputs. Only JPEG and WebP honor the quality knob.

Does my image get uploaded to a server?

No. The recompressor runs entirely in your browser as WebAssembly. Your image is decoded, re-encoded, and handed back to you locally — nothing is sent over the network.
