AI Image Upscaler

Our upscaler uses the browser's high-quality Lanczos/bicubic interpolation and optional unsharp mask sharpening to enlarge images while preserving detail. Processing happens entirely in your browser.

Upscaling always adds pixels that weren't in the original. Our high-quality interpolation minimizes blur and artifacts. The optional sharpening pass enhances edges for a crisper result.

You can upscale images by up to 4x. For example, a 500×500 image becomes 2000×2000. Keep in mind that larger scales will result in larger file sizes.
