Practical guide
Using Blur Image with confidence
Reviewed by LipiCode Editorial Team
What this tool helps you do
Blur replaces local detail with neighbouring colour information. Different blur styles suit softening, movement effects, mosaic privacy treatment, or edge emphasis, but visual obscuring is not always irreversible anonymization.
When it is useful
- Softening a distracting background
- Applying a motion effect
- Obscuring a selected region
- Reducing visible fine detail
A practical example
For a selected face or identifier, cover the complete region with a strong mosaic or blur and inspect the exported full-resolution image—not only the small preview.
Limitations and common mistakes
Weak blur may leave text or faces recognizable, and image metadata may retain other sensitive information. For high-risk redaction, remove the source pixels completely and verify the flattened export.
Frequently asked questions
Is blur safe for confidential redaction?
Not necessarily. Permanent opaque redaction is safer when information must be unrecoverable.
Why do image edges look dark?
Some kernels sample beyond the boundary; edge-aware handling or cropping can reduce the artifact.
