Frequently asked questions

What format does the compressed image use?

Output is saved as JPEG, which supports adjustable quality-based compression.

Is my image uploaded anywhere?

No, compression happens entirely in your browser using the Canvas API — nothing is sent to a server.

Why did the file size not shrink much?

Already-compressed images (like existing JPEGs) or very simple images may not shrink much further at high quality settings — try lowering quality more.
