Free Face Blur Tool – Anonymize Faces in Photos Instantly
Whether you're an educator sharing classroom photos, a parent posting to social media, or a developer handling user-generated content, protecting the privacy of individuals in photographs is essential. This tool automates the process of identifying and blurring human faces, saving you the time of manually painting blur masks in Photoshop or other editors.
Using lightweight in-browser machine learning (MediaPipe), the tool scans your photo, draws bounding boxes around detected faces, and automatically applies a privacy filter (blur, pixelate, or solid black box). You retain full manual control — you can click to remove a mask if a face was incorrectly detected, or drag to create a custom blur area for license plates, street signs, or sensitive documents. Processing is 100% client-side, ensuring your photos are never uploaded to our servers.
