Is 18IMG really free?

Yes. All 25 tools are free to use, with no signup, no file size limit, and no watermarks on output.

Are my images uploaded to a server?

No. Every operation runs entirely in your browser using WebAssembly. Your images never leave your device.

No. There is no signup, no login, and no tracking. Open the tool and start working immediately.

There are no artificial limits. The only constraint is the memory of your device, since processing happens locally.

No. The current tool uses classic edge detection and color posterization, which produces a stylized result but is not deep learning based.

Higher thresholds detect only the strongest edges, producing a cleaner cartoon. Lower thresholds detect more edges, producing a more detailed result.
