FAQ

Does compression damage the image?

It depends on the quality level chosen. At 80% quality the difference is almost imperceptible but the file can be 50-70% lighter.

Is image data sent to a server?

No, all compression happens in your browser using the Canvas API. The image never leaves your device.

What quality level is recommended?

For the web, 75-85% is the best compromise between visual quality and file size. For print, use 90-95%.
