Are my images uploaded to compress them?

No. Compression runs locally in your browser, and the tool reports the actual original and output sizes rather than an estimate.

Why didn't my image get much smaller?

Already-compressed images, or graphics with few colors, often have little remaining overhead to remove.

Can I compress several images at once?

Yes, add a batch of images and download every result together as a ZIP.
