What is Image Sharpener?
Enhance blurry or soft photos by applying sharpening filters with adjustable intensity. Uses unsharp mask convolution to increase edge contrast, bringing out details in photos that are slightly out of focus or softened by compression.
How to use
- Step 1 — Upload or drag-and-drop the image you want to sharpen (JPEG, PNG, or WebP).
- Step 2 — Adjust the sharpening strength slider. Start low (25%) for subtle enhancement, go higher (75-100%) for heavily blurred images.
- Step 3 — Toggle the before/after comparison to check the result, then download the sharpened image.
Result
Upload a slightly blurry smartphone photo. Set sharpening to 50% — text in the background becomes readable and facial features gain definition without introducing artifacts.
