Frequently asked questions

Can I resize to exact dimensions?

Yes. Turn off “Maintain aspect ratio” to stretch to an exact width and height; keep it on to fit inside the box without distortion.

Does resizing change DPI?

Pixel dimensions and DPI are independent. You can set the DPI written into the file in Settings.

Are my images uploaded?

No. This tool runs entirely in your browser, so your images never leave your device.
