FAQ

Are my uploaded images sent to a server?

No. All resizing happens entirely in your browser and images never leave your device.

Can I keep the aspect ratio while resizing?

Yes. With 'Lock ratio' enabled, changing either width or height automatically adjusts the other to preserve the original ratio.

Can I enlarge beyond the original size?

Yes, but enlarging beyond the original interpolates pixels and may look blurry.
