How it works
Auto quality — no guessing
Instead of moving a slider and hoping, just pick your target KB. The tool runs a binary search across quality levels until your image lands right at or under the limit. Every time.
Batch compress
Drop up to 20 images at once. They all get compressed to the same target — perfect for prepping a whole product shoot for email or a CMS upload.
Auto format saves even more
With Auto selected, the tool tries both JPG and WebP and picks whichever is smaller — WebP is often 25–35% smaller at the same visual quality.
PNG caveat
PNGs are lossless — quality settings don't shrink them like JPG/WebP. For large PNGs, switching to JPG or WebP output will give dramatically better compression.
