FAQ
Can sharpening recover a very blurry image?
The tool boosts edge contrast to improve perceived sharpness, but it cannot recreate missing detail: it works best on slight blur.
Can I control the sharpening intensity?
Yes, you can adjust the sharpening level to avoid an over-harsh look or visible artifacts on the image.
Do my photos leave my device?
No, sharpening is applied locally in your browser; your photos are never sent to any server.
