Private Lucaden images & media tool
Blur Faces Online
Find and anonymize front-facing faces locally with strong Gaussian blur or block pixelation, then download a separate PNG.
Free to use Your photo stays in this browser. The official versioned model is downloaded and hash-verified, while all face detection and pixel changes happen locally on this device.

Important
Check the result before relying on it
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
Practical details
What this Lucaden tool does
MediaPipe BlazeFace proposes face regions, then browser canvas pixelation or OpenCV.js Gaussian blur obscures those pixels on-device. Pixelation is the stronger default, but automated detection is never treated as a complete privacy guarantee.
The original stays unchanged; Lucaden creates a separate result in browser memory.

Questions
About this tool
Does this guarantee anonymity?
No. Detection can miss faces and visual clues may remain. Inspect every person at full size and use a solid manual redaction workflow for high-risk material.
Which mode is safer?
Large block pixelation usually removes more facial detail than ordinary blur, but neither replaces a deliberate privacy and disclosure review.
