Questions about blur image
Can it fully unblur a photo?
No. Sharpening makes a slightly soft image crisper, but detail lost to a heavy blur cannot be recovered.
What is blur good for?
Hiding a background or sensitive detail, or a soft-focus effect.
Is my photo uploaded?
No. Everything happens in your browser.
What the blur and sharpen settings do
Blur softens the whole picture by the number of pixels you choose, from 0 to 20, using your browser’s own blur. Sharpen runs afterwards: it applies a standard 3 by 3 sharpening filter at a strength from 0 to 100 percent. The picture keeps its size, and the result is saved in the same format with -edited added to the file name. The table gives a feel for the settings.
| Setting | What to expect |
|---|---|
| Blur 1 to 3 px | A soft-focus look that hides small flaws |
| Blur 4 to 8 px | Clearly blurred, with shapes still recognisable |
| Blur 12 to 20 px | Heavy blur, with only colours and rough shapes left |
| Sharpen 10 to 30% | A gentle lift for a slightly soft photo |
| Sharpen 50% and above | Strong, and it can add halos and grain |
Blurring for privacy, and its limits
The blur is applied to the whole picture, not to one part of it. To hide a single area, such as a watermark, use the Remove Watermark tool, which blurs only a box you draw. A light blur over text, a face or a number plate can sometimes still be read or guessed, so for anything sensitive cover it with a solid block in an image editor instead.
Sharpening cannot bring back detail that was never captured or that a heavy blur removed. It makes edges look crisper by boosting contrast along them, which helps a photo that is slightly out of focus but not one that is badly blurred. If you use both settings, the blur is applied first and the sharpening second.
