Sharpen Image

How do I make a blurry photo sharper?

Upload the image and increase sharpening intensity gradually. Sharpening enhances edge contrast, making the image appear clearer. Works best on slightly soft images.

Can sharpening fix out-of-focus photos?

Sharpening improves slightly soft images but cannot restore severely out-of-focus or motion-blurred photos. It enhances existing detail, not missing detail.

How much sharpening is too much?

If you see white halos around edges or the image looks crunchy/artificial, reduce intensity. Natural-looking sharpening should be subtle.

Will sharpening increase image noise?

Yes, sharpening can amplify existing noise. Start with low intensity. For noisy images, use noise reduction software first, then sharpen.

How do I sharpen scanned documents?

Use medium sharpening intensity on scanned text documents. This improves text legibility by enhancing edge definition between letters and background.

What is unsharp mask and is this tool using it?

Unsharp mask is a common sharpening technique that enhances edges by increasing local contrast. This tool uses similar edge-enhancement algorithms.

Can I batch sharpen multiple images?

Yes. Upload up to 50 images for batch sharpening. All images use the same intensity setting. Download as a ZIP file.

Should I sharpen before or after resizing?

Sharpen after resizing. Sharpening before resizing can be lost or exaggerated during the resize process. Apply sharpening as a final step.
