Are the pixels exact?

The AI draws the pixel look, so the grid is approximate. For a perfect grid, scale the result down and back up with nearest-neighbor in an image editor.

Yes. Every AI image tool here is free to use, with or without an account, and there is no watermark. You get 10 images a day without signing in and 30 a day with a free SandBase account. The allowance resets at midnight UTC.

Are my photos stored?

No. Your photo is sent to the image model for this one request and the result comes straight back to your browser. Nothing is saved to a gallery. A copy of the result is kept in a short-lived cache for 24 hours so that pressing the button twice does not use two runs.

Does it work on my phone?

Yes. The tools work in any modern mobile browser. Tap the upload area to pick a photo or take one with the camera, then download the result to your photos.
