Pixel Art Scaler
Pixel Art Scaler enlarges or reduces pixel art in a browser without blurring, using algorithms such as cleanEdge, hqx, and xBR.
About Pixel Art Scaler
Pixel Art Scaler is a browser tool for enlarging or reducing pixel art without blurring. The homepage says it is used for game development, social media, and personal projects. According to the homepage, scaling happens instantly in the browser and the image is never uploaded anywhere.
The tool offers several scaling algorithms. Nearest Neighbor, cleanEdge, Scale2x/Scale3x, Eagle, and Marching Squares keep the original colors. hqx and xBR blend in-between colors to smooth edges, and the output can be restricted to the original colors. Limits stated on the homepage include no support for animated GIFs (only the first frame is scaled), a requirement for a modern web browser, and a known bug where pasted images in Firefox may show inaccurate colors. Scales that are not pixel-perfect produce unevenly sized pixels, and very large scales may not be possible for some images. A legacy server-based version is also available. Pricing is unknown.
