What Is an Image Sharpener?

Image sharpening increases the contrast along edges within a photo, making detail appear crisper and more defined. It works by applying an unsharp mask or similar convolution filter to the image data.

ToolPop's sharpening tool offers an intensity slider so you can enhance detail without introducing unwanted artefacts.

How to Sharpen Image

1. Upload your image to the sharpen tool
2. Adjust sharpness level using the slider
3. Compare original and sharpened versions
4. Download your sharpened image

Frequently Asked Questions

Can sharpening fix a blurry photo?

Sharpening helps enhance details in soft images but won't fix severely blurred photos. Use it on slightly soft images.

What's the difference between unsharp mask and high-pass sharpening?

Unsharp mask is a traditional sharpening method, while high-pass provides more controlled edge enhancement.

Is sharpening applied in your cloud?
