FAQ
How do I reduce an image's size without losing too much quality?
Lower the quality slider gradually and watch the preview: around 70-80% you get a big size drop while quality stays nearly intact.
JPG or WebP: which format compresses better?
WebP usually produces a lighter file at equal quality, but JPG remains more universally compatible.
Is compression reversible?
No, lossy compression discards data: always keep your original file if you want to rework it later.
Are my images sent to a server to be compressed?
No, all compression happens in your browser. No image is uploaded and your files never leave your device.
