Frequently asked questions
Is my image uploaded to a server?
No. Compression runs entirely in your browser using the Canvas API — nothing is uploaded.
Can I convert to a different format while compressing?
Yes — choose JPEG, WebP or PNG as the output format before downloading.
Why does PNG not have a quality slider?
PNG is a lossless format, so there is no quality trade-off to adjust — only JPEG and WebP support it.
