What is Privopix?
Privopix is a privacy tool that automatically detects faces in your photos with AI and applies mosaic or blur. Beyond automatic detection, you can drag to add manual cover regions (which can be moved and resized afterward), letting you hide license plates, name tags, and more. It can also strip metadata such as EXIF, GPS, IPTC, and XMP in one go. Face detection runs in your browser using @vladmandic/face-api (TinyFaceDetector and SSD MobileNet v1).
How to use
- Pick the photo whose faces or private details you want to hide, or drag and drop it in.
- On first use the face-detection model loads from a CDN (cdn.jsdelivr.net). After that it starts from the cache.
- The AI automatically detects faces and shows mosaic or blur candidates over each detected face.
- Choose how to hide them, mosaic or blur, and adjust the strength.
- For anything automatic detection missed, drag on the preview to add a manual cover region (you can move or resize it later).
- Cover license plates, name tags, or documents showing an address using the manual regions.
- Enable metadata removal for EXIF/GPS/IPTC/XMP to erase location and camera information.
- Review the result, export the image, and use it for social posts or email attachments.
Great for
Hiding faces before posting
Before uploading event or travel group shots, hide the faces of passersby or friends who did not consent.
Sharing kids' photos
Blur a child's face before sending photos to family or friends to reduce the risk of reposting on social media.
Removing location data
Erase the GPS coordinates embedded in phone photos to prevent your home or workplace from being identified.
Masking documents
Before sharing a document showing a name, address, or number, paint over the relevant parts with a manual region.
Hiding license plates
Before publishing a photo with a car or motorcycle, cover the license plate to avoid the vehicle being identified.
Listing used items
Hide people caught in the background of a listing photo and strip camera metadata so you can post safely.
Privacy
Images are processed inside your browser and are never sent to a server. Only on first use does the face-detection model get fetched from a CDN (cdn.jsdelivr.net). Everything, from detection and mosaic processing to export and removal of EXIF/GPS/IPTC/XMP metadata, is completed entirely on your device.
FAQ
- Q. Are my photos sent to a server?
- A. No. Both face detection and the mosaic/blur processing run inside your browser. Your image is never sent to a server.
- Q. Can faces fail to be detected automatically?
- A. Detection can miss profiles, small faces, or dark photos. In those cases, drag to add a manual cover region over the spot.
- Q. What is the difference between mosaic and blur?
- A. Mosaic breaks the image into coarse blocks while blur smoothly softens it. Both can be set strong enough that the original detail is unreadable.
- Q. Can I move a manual region after adding it?
- A. Yes. A manually added cover region can be moved and resized after placement, so you can fine-tune its position to cover only what you need.
- Q. Can it also remove EXIF and GPS data?
- A. Yes. It can strip EXIF/GPS/IPTC/XMP metadata in one step, preventing leaks of capture time, location, and camera information.
- Q. Can I hide things other than faces?
- A. With manual regions you can cover anything besides faces, such as license plates, name tags, or text on documents.
- Q. Does it change the original photo?
- A. Edits only appear in the exported image; the original file on your device is left untouched. You can also redo edits before exporting.
- Q. Is it free to use?
- A. It is free. No registration is needed, and you get automatic face detection, manual masking, and metadata removal all included.
