Frequently asked questions
Are my images uploaded to a server?
No. Everything runs locally in your browser — your images never leave your device and nothing is stored.
Does it work on PNG?
Yes, though PNG is lossless — the quality slider mainly affects JPG and WebP, which can shrink the most.
Will quality drop?
Only as much as you choose. Higher quality keeps more detail; lower quality makes smaller files.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
