Image Sharpen

Upload your image and adjust the sharpening intensity slider to control how much enhancement is applied. Higher values create more pronounced sharpening, while lower values provide subtle improvements. Preview the results in real-time before downloading.

For most photos, a moderate sharpening level between 0.5 and 1.5 works best. Product photos and portraits benefit from subtle sharpening (0.5-1.0), while landscape photos can handle stronger sharpening (1.0-2.0). Avoid over-sharpening as it can create unwanted artifacts.

Sharpening can improve slightly blurry images by enhancing edges and details, but it cannot recover images that are severely out of focus or have motion blur. It works best on images that are already reasonably clear but need a clarity boost.

Sharpening increases detail in the image, which can slightly increase file size when saved, especially in formats like PNG. However, the impact is usually minimal. If file size is a concern, you can adjust compression settings when saving the final image.

Sharpening enhances edges and fine details by increasing local contrast at boundaries between different tones. Contrast adjustment affects the overall difference between light and dark areas across the entire image. Use sharpening for detail enhancement and contrast for overall tone adjustments.

While you can apply sharpening multiple times, it's not recommended as it can lead to over-sharpening, creating halos, artifacts, and an unnatural appearance. It's better to find the right intensity level in a single application rather than applying it repeatedly.

All major image formats support sharpening, including JPG, PNG, WebP, GIF, TIFF, and BMP. For best results, use lossless formats like PNG or TIFF during editing to avoid compression artifacts. Convert to JPG only as the final step after all sharpening adjustments are complete.

Sharpening should be the last step in your editing workflow, after all other adjustments like color correction, cropping, and resizing. This prevents sharpening artifacts from being magnified by subsequent edits. Sharpen specifically for your output medium: screen display requires less sharpening than print.

Sharpening halos are bright or dark edges that appear around high-contrast boundaries when over-sharpened, creating an unnatural appearance. Avoid them by using moderate sharpening values, applying selectively to areas that need it, and reviewing at 100% zoom to catch artifacts before they become problematic.
