Is the Image Resizer free?

Yes — the Image Resizer is completely free, with no account, subscription, signup, or usage limits.

Is my data uploaded or stored?

No. The Image Resizer processes everything locally in your browser. Your input is never uploaded, saved, or shared with any server.

Does the Image Resizer work offline?

Yes. Once the page has finished loading, the Image Resizer works without an internet connection.

Which browsers does the Image Resizer work in?

The Image Resizer works in all modern browsers, including Chrome, Firefox, Safari, and Edge — no plugins or extensions needed.

Will resizing reduce image quality?

Downscaling generally produces excellent results. For JPEG and WebP output, the Quality slider controls compression — keeping it at 85%+ maintains visually lossless quality for most photos.

Can I upscale an image with this free resizer?

Yes — you can increase dimensions beyond the original, but upscaling always results in some blurriness since no new pixel information is added. For AI upscaling, a dedicated tool is recommended.
