Quick answer: To blur faces in a photo, drop it above. An on-device model finds the faces and shows each one hidden in a box; drag over anything it missed, tap ✕ on a box to keep that area, pick blur, pixelate or a solid bar, and save. Nothing is uploaded, and the saved photo carries no location or camera data.

Frequently Asked Questions
Yes — completely free, no limits, no watermarks, and no account required. Convertlo runs entirely in your browser, and your photos never leave your device.
No. Face detection and blurring both happen locally in your browser using WebAssembly and the HTML canvas. Your images never leave your device — which is exactly what you want when the whole point is privacy.
It uses a compact on-device face-detection model (the Tiny Face Detector) to locate faces, then hides each one by shrinking that area and enlarging it again — the detail is gone from the file, not just softened. No cloud service or account is involved.
Automatic detection works best on clear, front-facing faces; very small, turned or partly hidden faces can be missed. Every face it finds is shown in a box, so check the photo: drag over anything it missed, and tap ✕ on a box that should stay visible. If it finds no face at all, you can still mark them by hand.
Yes. Choose blur, pixelate or a solid bar, each light, medium or strong. For something that must be completely unreadable — a number plate, a document — the solid bar leaves nothing to recover.
JPG, PNG, WebP and iPhone HEIC photos all work. A JPG is saved as a JPG; other formats are saved as PNG. The saved photo carries no location or camera data.
