Frequently asked questions

How does the image compressor work?

Your image is decoded and re-encoded locally with the browser Canvas API. Lower the quality or the dimensions to shrink the file size.

Are my images uploaded to a server?

No. The whole process runs in your browser. Your images never leave your device and are never uploaded.

Why is my PNG not getting smaller?

PNG is a lossless format, so the quality slider does not apply. Reduce the max dimensions or switch the output to WebP or JPEG to shrink it.
