WebP and AVIF formats offer better compression than JPEG at the same visual quality.
For photos, quality 80 is often indistinguishable from the original while saving 60-70% file size.
Use batch mode to compress hundreds of images at once — processing stays in your browser.

Does compression always reduce quality?

Not visibly. Modern codecs like MozJPEG and libwebp can reduce file size by 60-80% with changes invisible to the human eye.

What quality setting should I use?

For web images, 75-85% is ideal. For print, use 90-95%. Below 70% you may notice artifacts in detailed areas.

Is my data safe during compression?

Absolutely. ImageMint processes everything in your browser using WebAssembly. Your images are never uploaded to any server.
