What does the Filter Radius control?

The radius determines the size of the details affected. A smaller radius targets fine textures, while a larger radius affects broader edges.

Which blend mode should I use?

Overlay is the recommended default for most sharpening tasks, as it balances contrast and detail enhancement effectively.

Can I extract only the high-frequency details?

Yes, select 'Details Only' in the Output Mode to generate an image containing only the isolated high-pass data.

What file formats are supported?

You can upload JPEG, PNG, WebP, GIF, BMP, and TIFF files. You can also choose to export in JPEG, PNG, or WebP.

Does this tool reduce image quality?

The tool processes your image based on your chosen output format and quality settings. Using PNG format ensures maximum quality retention.
