Frequently asked questions

Does compressing an image reduce quality?

Some quality loss is unavoidable with lossy formats like JPG, but the compressor lets you pick a quality level so you can balance size against how much loss is visible.

Are my images uploaded to a server?

No. Compression runs entirely in your browser using the Canvas API — your files never leave your device.

What's the difference between compressing and resizing?

Compressing reduces file size by re-encoding the image at a lower quality; resizing reduces file size by shrinking the pixel dimensions. Use both together for the smallest result.
