What is Image Sharpener?
Fix blurry or soft photos with adjustable sharpening filters. Uses unsharp mask convolution to increase edge contrast, so photos that are slightly out of focus or softened by compression get their details back.
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.
