How to use Sharpen a JPG Picture
- 1. Upload the JPG picture. Drop or browse for the .jpg or .jpeg file that looks soft or slightly out of focus. It loads into the preview so you can spot the areas needing more definition.
- 2. Set the Sharpen strength (%). Increase Sharpen strength (%) to accentuate edges and fine detail more strongly. Push it too far on a heavily compressed photo and you risk exaggerating existing JPG artifacts.
- 3. Download the sharpened picture. The tool boosts local contrast along edges to make details read more crisply. Download the sharpened JPG once the detail level looks right without introducing halos.
When to use Sharpen a JPG Picture
Sharpen a JPG Picture increases edge contrast to bring out detail in a soft or slightly blurry photo. It works well on scans, resized images and gently out-of-focus shots where the detail exists but reads as mushy.
- Fixing a soft phone photo. A photo taken in low light came out slightly blurry; sharpening at moderate strength brings back some crispness to edges without wrecking the smoother areas.
- Crisping up a resized image. A photo that was scaled down for the web looks a bit soft after resampling; sharpening it restores perceived detail that resizing naturally blurs.
- Making scanned text more legible. A document scanned as a JPG has slightly fuzzy text edges; sharpening at strength 50 makes the letters read more clearly for a report attachment.
- Enhancing detail before printing. A photo destined for print benefits from a touch of extra sharpening since printing processes tend to soften fine detail further.
Examples
