    Real detail, not just contrast

    Classic sharpening filters boost contrast at edges, which amplifies noise and creates halos. This tool first reconstructs the image with Swin2SR (lightweight ×2), rebuilding clean edges and textures, and then applies a controlled sharpening pass.

    Sharpening levels

    • Light: for portraits and skin texture
    • Normal: for general photos
    • Strong: for noticeably soft images

    Small and fast

    The model is about 8 MB, downloads quickly and is cached. Compare the difference instantly with the before/after slider. Your images are processed on your device.

    Where it helps

    Photos with slight focus misses, screenshots, small product images and low-quality images from the web.

    How to use AI Image Sharpener

    1. Upload the image to sharpen.
    2. Choose the sharpening level.
    3. Compare with the before/after slider.
    4. Download the sharpened image.

    Why use this tool?

    Produces natural, crisp results without the artificial look of simple filters.

    FAQ

    Can it fix a completely out-of-focus photo?

    It noticeably improves slightly soft or blurry photos, but can't bring back detail that's completely lost.

    Does the image size change?

    The model upscales ×2 during processing; the result is exported to suit your original size.

    I want to enlarge the image.

    Use the AI Photo Enhancer for upscaling.
