Which image formats are supported?

JPG, PNG, WebP, and AVIF are supported for input and output. Browser support may enable additional inputs.

Can I keep the original aspect ratio?

Yes. You can lock aspect ratio to avoid distortion or unlock it for free scaling and cropping.

Are images uploaded to a server?

No. Resizing runs locally in your browser, so your images aren’t uploaded or stored on a server.
