FAQ

Does compression hurt quality?
Moderately lowering JPG/WebP quality is usually invisible to the eye while cutting file size dramatically. For maximum fidelity keep quality at 80% or above, or export PNG.
Is my image uploaded anywhere?
No. Compression runs locally on a Canvas in your browser — the image never leaves your device, so it is safe for sensitive content.
What happens to transparent PNGs?
Exporting to JPG turns transparent areas white. Choose PNG or WebP output to keep transparency.
