Frequently Asked Questions

Sharpening enhances edge definition and brings out detail in slightly soft images. It cannot fully recover severely blurry or out-of-focus photos.

Moderate sharpening works best — over-sharpening creates a halo effect around edges and can make images look artificial.

Apply sharpening as the final editing step, after resizing and other adjustments. Sharpening is also recommended after upscaling to restore crispness.

About This Tool

Image sharpening enhances the perceived detail in a photo by increasing edge contrast — the difference in pixel values across boundaries between different areas of the image. This makes fine textures, hair strands, text, and architectural details appear crisper and more defined. PixlTools uses an unsharp mask algorithm (the industry standard used in Photoshop, Lightroom, and Sharp itself), which works by subtracting a blurred version of the image from itself to detect edges and then amplifies them. The key parameters are sigma (the radius of edge detection) and the strength (how aggressively edges are amplified). PixlTools applies a balanced, professionally tuned default that works well for most photographs — sharp enough to visibly improve clarity without introducing the halo artifacts that plague over-sharpened images.
