Our AI face detection operates entirely within your web browser using advanced lightweight machine learning models. When you select an image, the photo is never uploaded to an external server or cloud database. Instead, the artificial intelligence algorithm, powered by WebAssembly (WASM) and TensorFlow.js, scans the pixel data locally on your device's processor. It rapidly identifies facial landmarks such as eyes, noses, and mouth structures to determine the presence and exact coordinates of human faces. This local processing ensures lightning-fast detection speeds, typically highlighting faces in less than a second, regardless of your internet connection speed. Because the AI model runs on the client side, your privacy is absolutely guaranteed—nobody, not even our development team, can see or access the photos you are editing. This makes it the safest option for handling sensitive or confidential media.

Absolutely. One of the most powerful features of Blur Face is its ability to handle multiple faces simultaneously with incredible precision. When you load a group photo—whether it’s a classroom picture, a crowded street scene, or a corporate event snapshot—our AI engine instantly scans the entire canvas and detects every single face. By default, you can click the "Blur All" button to instantly apply your chosen privacy effect (such as standard blur, pixelation mosaic, or solid black censor bars) to every detected individual at once. This batch processing capability saves you significant time compared to manually drawing boxes over each person. If there are specific people you want to remain visible, you can simply tap or click on their individual blur masks to remove the effect, giving you complete granular control over exactly who is anonymized and who stays in focus.

Yes, it is fundamentally safe to process highly sensitive, confidential, or private photos using Blur Face because of our unique offline-first architecture. Most online photo editors require you to upload your files to their remote servers for processing, which creates significant security vulnerabilities, potential data breaches, and privacy compliance issues under laws like GDPR or CCPA. In contrast, our tool processes all images locally directly within your web browser (client-side processing). Your photos literally never leave your smartphone, tablet, or computer. There is no cloud storage, no temporary server caching, and no data collection of your imagery. Once you close the browser tab, all image data is instantly and permanently cleared from the application's memory. This makes Blur Face an ideal and secure solution for journalists, legal professionals, medical staff, and everyday users handling sensitive material.
