How much sharpening should you use?
Use lower strength for portraits and already-detailed photos. Higher strength can help screenshots, scanned text, and product images, but too much sharpening may create bright or dark halos around edges.
Sharpening improves local contrast; it cannot restore detail that was never captured or fully correct severe motion blur.
常见问题
Can sharpening fix a blurry photo?
It can improve edge clarity in a slightly soft image, but it cannot fully recover detail from strong focus blur or motion blur.
Does the tool change image dimensions?
No. The output keeps the processed image dimensions and downloads as PNG.
我的图片上传了吗？
No. Your image stays in your browser and sharpening runs locally.
