When the Image Blur Tool seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
Faces are still recognisable
Raise the strength until details are genuinely unreadable - half measures do not protect privacy.
The whole image is soft, not just the background
This tool blurs globally; crop or mask the subject elsewhere if you need selective blur.
It looks blotchy at high strength
Very strong blur on noisy photos magnifies grain - reduce source noise first.
The result is too small
Download at full resolution; preview quality is only for checking.
Blur bands appear around edges
Extreme values can show artefacts - step back a few points of strength.
I wanted only the edges blurred
For vignette-style or selective effects use the vignette or crop tools instead.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Blurring too little to actually hide anything
- Blurring the whole image when only part needed hiding
- Applying heavy blur and then trying to sharpen back
- Exporting a blurred image at low resolution
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
Can I blur only one area?
This tool applies blur across the whole image - use cropping or a dedicated editor for selective regions.
Is blur good for privacy?
Strong blur hides details well, but for faces and plates pixelation or solid masks are harder to reverse.
Will blurring reduce file size?
Sometimes slightly - smooth images compress well, but blur is a visual effect, not a compressor.
Is my photo uploaded?
No - the blur runs in your browser and your file stays local.
