Face blur for practical photo privacy
Pillar guide: How to Blur Faces for Privacy (Manual + AI Workflow)
Privacy blur should hide identity while keeping the rest of the photo useful. If blur is too weak, facial features stay recognizable; too strong and the whole image looks damaged.
Start with AI face detection to save time, then add manual blur boxes for misses, side profiles, or small background faces. This is common in events, classrooms, and street shots.
Processing happens in your browser. Your image stays local while the model runs, and you can export PNG, JPG, or WebP once the blur coverage looks right.
Face blur is a privacy task, not a beauty effect. The goal is to remove identifiable detail while preserving enough context for the scene to stay understandable.
This tool gives you two paths: draw manual blur boxes for exact control, or run on-device AI detection to auto-place regions and refine the result manually.
Everything runs in your browser. After you confirm coverage in preview, export one flattened image in PNG, JPG, or WebP.
Blur workflow
- Upload your image and start by drawing blur boxes manually, or run AI detection to auto-mark faces.
- Adjust face padding to include hairline and jaw area when needed.
- Tune blur strength until facial details are no longer recognizable.
- Add or remove regions, then export at the original image resolution.
Common use cases
- Event and classroom photos where bystanders should stay private.
- Street photography samples for public case studies and blog posts.
- Customer support screenshots and reports that include people.
Practical tips
- Use AI detection first for speed, then manually fix missed side profiles or tiny background faces.
- Increase padding for angled faces so ears and profile edges are covered.
- Check results at 100% before export; a blur that looks strong on thumbnail may still be reversible on large images.
Limitations to know
- Automatic detection can miss occluded, very small, or extreme-angle faces.
- Blur reduces recognizability but is not a legal guarantee of anonymization in every jurisdiction.
- Very high blur can draw attention to the redacted area and hurt visual quality.

Frequently asked questions
Is AI face detection mandatory?
No. You can blur entirely manually by drawing boxes on the image. AI detection is optional and meant to speed up the first pass.
Does this upload faces to a server?
No. Detection and blur rendering are designed to run locally in your browser, similar to other on-device tools in this project.
Can I blur license plates too?
Yes. Manual blur boxes can be used on faces, license plates, screens, badges, or any region that needs redaction.
What format should I export for privacy blur?
PNG preserves quality best; JPG or WebP usually save space. The privacy result depends more on blur strength and coverage than on format.
