Sharpen Image
Rescue slightly soft or blurry images with an unsharp mask — free, private, no upload required. Ideal after resizing. All processing happens in your browser.
100% Private
Your image is processed entirely on your device. Nothing is uploaded, stored, or transmitted to any server.
What it does
Applies an unsharp mask to enhance edge definition and recover detail lost during resizing or compression. Three sliders let you fine-tune amount, radius, and threshold.
Limitations
Animated GIFs are exported as a static PNG frame. Very large images (above 10,000 px) are not supported. Extreme settings may introduce halos or noise artifacts.
