Sharpen blurry photos and upscale images with AI
About ImageSharpen
ImageSharpen is a free browser-based tool for people who need a clearer version of a soft or low-resolution photo. It is aimed at anyone with an old family picture, a blurry screenshot, a small product photo or a compressed image from a chat app. Users upload a file in JPG, PNG or WebP, and the AI rebuilds edge detail and texture, with a before and after slider to compare results before download.
The tool also offers a 4x upscaler that enlarges small images and tries to fill in fine detail, which the site suggests for printing or sharper listing images. Results are strongest on slightly or moderately blurred photos, while heavy motion blur and very small faces give limited results. No account or software is needed, and the site says uploads are deleted automatically after processing.
What sets it apart, according to the site, is that sharpening, resolution boost and compression cleanup happen in one step without settings to adjust. It works on phone or desktop.
