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.

32x32 to 64x64 pixels is a good range for avatars. Smaller values produce a more abstract result.

The tool does a nearest neighbor downscale to preserve hard edges, which is the standard approach for converting photos to pixel art.
