Frequently asked questions
How much smaller will my image get?
It depends on the image, but photos often shrink 50–80% with little visible quality loss when exported as JPG or WebP.
Does compressing reduce quality?
JPG and WebP use lossy compression, so lower quality settings discard more detail. Use the live preview and file-size estimate to find the best balance for your image.
Are my images uploaded to a server?
No. Compression happens entirely in your browser with the Canvas API, so your images stay on your device.
