Compress images: what the result contains
Reduce JPG or WebP file sizes with local quality controls.
File size falls before dimensions do
Compression changes encoding quality; it doesn’t automatically make an image smaller in pixel dimensions. Photographs usually tolerate more compression than screenshots, text-heavy graphics or line art.
Small text, hair, foliage and fine texture reveal compression damage sooner than large flat areas.
When Compress images isn’t the right endpoint
Use Resize Images when width and height are the problem. If transparency must be preserved, check the output format before converting away from PNG or another alpha-capable format.
