Tip: PNG is lossless, so the quality slider won't shrink it much — switch to JPG or WebP for the biggest size reduction on photos.

Frequently asked questions

How much smaller will my image get?

It depends on the original image and format, but JPG and WebP at 70-85% quality typically cut file size by 50-80% with little visible difference.

Which format compresses best?

WebP usually produces the smallest files at a given quality level, followed by JPG. PNG is lossless and best for graphics/screenshots, not photos.

Is compression reversible?

JPG and WebP compression at less than 100% quality is lossy — some detail is permanently discarded to save space. Keep your original file if you might need it later.
