Quick reference
- ● Low intensity = subtle edge enhancement.
- ● High intensity = aggressive sharpening with visible halos.
- ● Always sharpen as the last step in editing.
- ● Everything runs locally — your image never leaves your device.
Why it matters
Sharpening counteracts the softness introduced by resizing, compression, or slight misfocus. It makes text more readable, textures more tactile, and product photos more appealing. Applied correctly, it is the difference between a photo that looks professional and one that looks flat.
Frequently asked questions
What is image sharpening?
Image sharpening increases contrast along edges, making details appear crisper and more defined. It works by applying a convolution kernel that boosts the difference between adjacent pixels. Sharpening does not add new detail — it enhances what is already there.
When should I sharpen an image?
Sharpen after resizing (especially downsizing), after applying blur, or whenever an image looks slightly soft. It is also useful for rescuing slightly out-of-focus shots. Apply sharpening as the last step in your editing workflow.
Can I over-sharpen an image?
Yes. Over-sharpening creates harsh edges, bright halos around objects, and visible noise artifacts. Start with a low intensity and increase gradually. If you see bright outlines around edges, reduce the sharpening amount.
