Detect and blur or pixelate faces across whole photo batches with on-device BlazeFace (one shared model download for the batch). Faces need confidence above 0.5 and size above 8px; faceless files are skipped with an error. Outputs PNG as <name>-anonymized.png — local processing, 2 free batches a day.

Detects faces in one uploaded photo with the on-device BlazeFace model (TensorFlow.js, downloaded lazily on first run) and blurs every detected box at a fixed 15px. Exports PNG as blurred_faces.png with a face-count toast — free to start with no signup.
Every face covered automatically: upload a group photo and BlazeFace finds each face on your device, pixelated into 12px+ blocks that cannot leak back. Pixelate, soft-blur, or solid-cover modes, PNG export, refine-in-editor link. Free, no signup, nothing uploads.
Hide faces in photos in your browser: opens with the Blur tool armed — drag over each face to pixelate or soft-blur, baked into the export. Blocks stay chunky (8px+) so nothing leaks back. Free, no signup, nothing uploads.
Burn one shared SRT subtitle file permanently into a whole batch of videos with font-size and bottom/top/middle position control. Course creators hard-sub 20 lessons for platforms that ignore caption files — FFmpeg WASM, 2 free batches a day.
Bind hundreds of JPG, PNG, or WebP images into one multi-page PDF with page size, orientation, and fit control. Agents compile 80 property photos into a brochure — local jsPDF work, 2 free batches a day.
Faces pass only above 0.5 confidence and 8px size — front-facing, well-lit faces pass reliably; profile angles, sunglasses, and tiny background faces get skipped. For 100 event photos, re-run misses individually rather than trusting blind automation for publication.
Heavy pixelation is hardest to reverse; light blur can sometimes be enhanced back, so use high strength (up to 50px blur) where identity protection is legally required. No solid-bar mode exists — pixelate at low strength values for the blockiest cover.
No — detection runs on-device in your browser with TensorFlow.js; images never leave your device. Originals stay untouched in memory; only anonymized copies export.
Still images only in this tool — export video frames first, anonymize the batch, and rebuild. For full video redaction, use a dedicated video anonymization workflow instead.

Bulk EXIF Stripper & Injector
Strip all EXIF metadata from JPEG, PNG, and WebP photos by re-encoding each to JPEG at quality 0.95 (files renamed *-noexif.jpg). Strip-only — no inject mode exists. Agents clean 500 listing shots before upload — local canvas work, 2 free batches a day.
