Sometimes a sharper less aliased image is better. NichePhotoTool's Online Image Re-Aliaser will automatically detect up to 16 dominant colors in your image and sharpen it by removing anti-aliasing effects with similar speed and results to professional software, but in only one click and without needing to download or install anything. We require no sign in, no software download, and no email. This tool is totally free online and has absolutely no watermarks. All files are processed in browser so we never see your images.

How to Use

Simply drag or upload your image, the tool will predict the optimal number of colors, but you are free to change this number and the colors by clicking on them. Once you are satisfied click to see your result. Feel free to tweak and click again to rerun. When you are ready simply click download to save your image.

Best Used for Logos, Pixel Art, and Graphics

This tool is best used on logos, pixel art, graphics, or basic images. However, using it on complex images can produce fun effects as well. This tool does work with vector bounds, so in cases where blockiness is absolutely required consider using the repixelator tool.

I first decided to make this tool in an attempt to restore a graphic image that I screenshot at an improper zoom resulting in soft edges where they used to be sharp. I am happy to say that this tool was able to recover the image, restoring it to its original sharpness.
