Frequently Asked Questions

What sharpness level should I use?+

Start with level 5-7 for subtle enhancement. Use 10-15 for moderate sharpening. Use 15-20 for heavy sharpening. Adjust based on your image.

Can I reverse sharpening?+

No, sharpening is permanent in the output. Always keep your original image. You can always apply sharpening again with different settings.

Does sharpening increase file size?+

File size can change because the processed image is encoded again as JPG at 90% quality.

What formats are supported?+

Supported browser-readable images can be processed by the tool. The generated result is encoded as JPG at 90% quality.

Will sharpening improve a very blurry image?+

This adjustment can make existing edges and tonal differences appear stronger, but it does not reconstruct detail that is missing from a heavily blurred source image.

Is the sharpen tool really free?+

You can use the available sharpening controls without creating an account.
