Where does the image resizing process happens?

All resizing runs locally in your browser on your device. Images are not uploaded to a server, stored, or shared, so the process stays private.

Will resizing reduce image quality?

Making an image smaller usually keeps good visual quality. Enlarging images may look softer because new pixels are interpolated. For a larger file, try the Image Upscaler.

Can I keep the original aspect ratio?

Yes. Turn on lock aspect ratio and changing width or height will update the other dimension automatically.

Is my image stored anywhere?

No. Resizing happens entirely in your browser.

Is this online image resizer safe to use?

Yes. Your images are processed entirely in your browser and are not uploaded to our servers, stored, or shared. This keeps your files private on your device.
