Tips

Quality 80 is the sweet spot

Most images look identical at 80% quality but are 2–3× smaller than the original.

WebP for the web

WebP provides the best compression for web use — supported by all modern browsers.

PNG stays lossless

If the original is PNG and you keep the format, quality setting is ignored (PNG is lossless).
