About this tool
Fastols' Sharpen Image tool uses the professional Unsharp Mask technique to bring out edges and detail in your photo and make it noticeably crisper — no Photoshop or other software needed.
It's great for photos that came out a bit soft from the camera, or lost detail after compression or resizing. Drag the intensity slider until you like the result, and check the live preview before downloading.
