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 keep the aspect ratio?
Yes — leave the lock on and width and height stay proportional. Turn it off to set exact dimensions.
Can I enlarge an image?
Yes, but upscaling can look soft because the tool can't invent new detail.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
