Why PrivaFace?

AI Face Detection

Powered by Google MediaPipe BlazeFace, which accurately detects multiple faces simultaneously — including partial faces, faces at angles, and small faces in group photos.

Privacy First

All processing happens in your browser using WebAssembly — photos are never uploaded to any server at any point.

Artistic Effects

Choose gaussian blur for smooth natural softening, pixelation for mosaic-style anonymization, or bokeh for beautiful portrait-mode background blur — all with adjustable intensity.

What is PrivaFace?

PrivaFace is a free, browser-based AI tool that automatically detects and blurs faces in photos to protect personal privacy — ideal for sharing group photos, event pictures, or any image where you want to anonymize individuals. It also offers background bokeh for professional-looking portrait effects. All processing happens entirely in your browser using the MediaPipe WebAssembly model — no server uploads, no cloud processing, no privacy concerns.

How to Use PrivaFace (3 Steps)

  1. 1

    Upload Your Photo

    Select a photo (JPEG, PNG, or WebP format) and choose your processing mode: face blur to anonymize detected faces, or background bokeh to apply a portrait-style depth-of-field effect that blurs everything except the main subject.

  2. 2

    Adjust Settings

    The AI automatically detects all faces in the image, including partially visible faces and those at angles. Review the detections, adjust blur type (gaussian or pixelate) and intensity with the slider, toggle individual detections on or off, and preview the result in real time.

  3. 3

    Download Result

    Download your processed photo as a high-quality PNG or WebP file. All face detection and blurring was performed locally in your browser — the original photo and the result never leave your device.

Why Browser-Based Face Blur Is Safer

Most face blur tools and privacy protection apps upload your photos to cloud servers where the AI processing runs on their infrastructure — meaning your personal photos, including recognizable faces, are transmitted to a third party. PrivaFace runs the entire MediaPipe AI model locally in your browser using WebAssembly. Your photos never leave your device at any point during detection, blurring, or export.

Frequently Asked Questions

PrivaFace uses Google MediaPipe's BlazeFace model — one of the most accurate lightweight face detectors available. It is specifically optimized for browser-based inference using WebAssembly and can detect multiple faces simultaneously, including partially visible faces and faces at various angles.
Face blur mode uses AI to detect all faces in the photo and applies blur only to those regions, leaving the rest of the image untouched — ideal for protecting identities in group photos or crowd scenes. Bokeh mode detects the main subject (typically a person) and blurs the background instead, creating a professional portrait effect that mimics a shallow depth-of-field lens.
Yes. Face blur mode offers two blurring styles: gaussian blur for smooth, natural softening; and pixelation (mosaic-style) for a distinct anonymization effect. You can also adjust the blur intensity with a slider to find the right balance between anonymization strength and natural appearance.
Yes. PrivaFace runs entirely in your browser using WebAssembly, so it works on any modern browser including mobile Safari on iPhone and Chrome on Android. Touch controls work for manual adjustments on mobile screens.
Yes. PrivaFace is completely free with no account required, no watermarks added, and no usage limits. All face detection and blurring runs locally in your browser using the MediaPipe WebAssembly model, so your photos never leave your device at any point.
