FAQ
What’s the best image format?
WebP offers the smallest file sizes, JPG is best for photographs, and PNG is ideal when you need transparency.
Will compression blur my image?
Only if you choose very high compression. Moderate compression maintains excellent visual quality and is nearly indistinguishable from the original.
