# MaskMyBody > Free on-device photo privacy, biometric redaction, and metadata stripping tool. MaskMyBody (https://maskmybody.com) is an open-access client-side photo privacy and redaction utility. It operates 100% in-browser via WebAssembly and MediaPipe computer vision models to automatically detect and mask human biometrics (faces, peace-sign fingertips) and strip embedded EXIF GPS location data without cloud uploads or remote processing. ## Core Capabilities - **Biometric Fingertip Redaction**: Detects 21-point 3D hand landmarks and covers distal fingerprint ridges in peace sign selfies to prevent biometric ridge cloning. - **Facial Privacy Mesh**: Detects 468-point 3D facial landmarks and covers eyes or full face with flat color fills, cryptographically random noise, or privacy emojis. - **GPS EXIF Neutralization**: Renders clean HTML5 canvas image blobs on export, completely dropping embedded camera metadata, GPS latitude/longitude, and timestamps. - **Irreversible Masking (Anti-Deconvolution)**: Replaces pixels with solid flat fills (0x00) or cryptographic noise rather than reversible Gaussian blurs, preventing AI deconvolution tools (e.g., Depix) from recovering sensitive data. - **Zero-Server Airgap**: All image decoding, landmark detection, mask rendering, and file export happen strictly in local client memory. Photos are never uploaded to any remote server. - **Batch Processing**: Optional Pro batch processing for up to 50 photos per batch with 1-click ZIP export. Single-photo processing is 100% free with no account required. ## Primary Tools - [Blur Fingertips in Photos](https://maskmybody.com/tools/blur-fingertips-photo): Protect fingerprints in peace sign selfies from biometric ridge extraction and synthetic mold synthesis. - [Remove GPS from Photos](https://maskmybody.com/tools/remove-gps-from-photo): Strip embedded GPS coordinates and EXIF metadata for marketplace listings (Craigslist, Facebook Marketplace). - [Hide Kids Faces in Photos](https://maskmybody.com/tools/hide-kids-faces-photo): Protect children's facial biometric identity against commercial AI scrapers and sharenting risks. - [Redact ID Document](https://maskmybody.com/tools/redact-id-document): Redact SSN, driver's license numbers, and signatures locally before emailing rental or loan applications. - [Censor Photo with Emoji](https://maskmybody.com/tools/censor-photo-with-emoji): Place privacy emojis over faces for social media sharing while preserving photo aesthetics. - [Private Face Blur No Upload](https://maskmybody.com/tools/face-blur-no-upload): Blur faces 100% in local browser memory without transmitting files to third-party cloud servers. - [Pixelate Face in Photo](https://maskmybody.com/tools/pixelate-face-photo): Pixelate and censor faces with automatic AI detection and reversible deblur protection. - [Blur License Plate](https://maskmybody.com/tools/blur-license-plate): Censor vehicle license plates and strip camera GPS location data before posting car listings online. - [Black Out Text in Photo](https://maskmybody.com/tools/black-out-text-photo): Permanently black out confidential text, passwords, and SSNs with 100% opacity and zero alpha leakage. - [Privacy Tools Directory](https://maskmybody.com/tools): Full directory of on-device privacy tools with category filtering and instant launchers. ## Technical Comparisons & Forensics - [Why Blur Is Not Safe](https://maskmybody.com/compare/why-blur-is-not-safe): Technical proof demonstrating why Gaussian blur and mosaic pixelation are computationally reversible via AI deconvolution. - [Apple Markup Opacity Trap](https://maskmybody.com/compare/apple-markup-opacity-trap): Forensic analysis explaining how default iOS markup highlighter strokes (85% opacity) leak private text when exposure is increased. - [MaskMyBody vs. Redacted.app](https://maskmybody.com/compare/maskmybody-vs-redacted-app): Comparison between automated biometric AI landmark detection and manual rectangle redaction. - [MaskMyBody vs. PrivacyBlur](https://maskmybody.com/compare/maskmybody-vs-privacyblur): Comparison between instant zero-install web browser processing and mobile-only app installations. - [MaskMyBody vs. Signal Blur](https://maskmybody.com/compare/maskmybody-vs-signal-blur): Standalone cross-platform photo privacy tool vs. chat-restricted mobile utility. - [7 Best Photo Redaction Tools Audit](https://maskmybody.com/compare/best-photo-redaction-tools): Security, telemetry, and forensic audit of the top 7 redaction applications of 2026. ## Research Guides - [Biometric Fingerprint Defense Guide](https://maskmybody.com/guides/protect-fingerprints-in-photos): Technical analysis of camera megapixel growth (48MP–200MP) and optical ridge harvesting from social photos. - [Marketplace Geotag Scrubbing Guide](https://maskmybody.com/guides/remove-gps-exif-facebook-marketplace-craigslist): How Craigslist and Facebook Marketplace photo buyers extract exact home addresses from listing images. - [Child Facial Privacy & Sharenting](https://maskmybody.com/guides/sharenting-child-facial-privacy-guide): Safeguarding minors from automated facial recognition scrapers and long-term biometric profiling. - [ID & Driver's License Redaction Guide](https://maskmybody.com/guides/redact-id-drivers-license-ssn-safe): Safely sharing identity documents for rental and loan applications. - [Facial Recognition Defense & PimEyes Guide](https://maskmybody.com/guides/protect-photos-from-pimeyes-face-search): Blocking AI face search engines (PimEyes, FaceCheck.ID) from harvesting faceprint vector embeddings. - [Guides & Research Hub](https://maskmybody.com/guides): Full research library. ## Optional & Deep Technical Documentation - [Full Technical Documentation & Architecture](https://maskmybody.com/llms-full.txt): Complete whitepaper covering MediaPipe WASM implementation, mathematical threat vectors, benchmark tables, and academic citations. - [Zero-Server Privacy Policy](https://maskmybody.com/privacy): Formal airgap guarantee and GDPR non-collection declaration. - [Terms of Service](https://maskmybody.com/terms): Merchant of record terms, non-liability declarations, and digital fulfillment policies.
