Do you upload my photos to compress them?

No. Compression runs locally for this tool, so personal photos are not sent to a remote optimizer.

Can I compress PNG without losing transparency?

PNG handling aims to keep transparency where the pipeline supports it. Extremely complex alpha images may need a specialized PNG optimizer.

What size reduction should I expect?

Results vary by content. Busy photos often shrink a lot; already-optimized or flat graphics may shrink less.

Is the image compressor free?

Yes. Compress and download—no account required.

Frequently asked questions
