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.

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