The Subpixel Favicon Generator
Upload an image, get an awesome favicon.
Please take the time to at least crop your picture to a square. Non square images will produce non awesome favicons.
The output will be 16x16. Crop your pictures WAY down to just the interesting part. Crop this into this.
Finally, line art with big solid colors will turn out better than photos.
Get in touch with me if you would like different resolutions, different pixel orders, or subpixel animations.
