Frequently asked questions

Is my image uploaded to a server?

No. Compression runs entirely in your browser, so your image never leaves your device, which is ideal for private photos.

How does the compression work?

It re-encodes the image at a lower quality and, optionally, resizes it so the longest side fits the limit you set. Both reduce file size.

Which formats are supported?

Common web image formats such as JPEG, PNG and WebP. Photographs usually shrink the most, since they compress well at slightly lower quality.
