Will it work on EU / UK / multi-line plates?

It works on most plates that face the camera. Oblique angles, partial occlusion, and stacked / multi-line plates are harder. The editor's draw-your-own region tool is the answer when auto-detection misses.

Why pixelate instead of blur?

Pixelation is the convention for license plates in published photography because it's visually obvious that something has been removed. Gaussian blur can look like depth-of-field — viewers might assume the plate is just out of focus.

Can someone reverse the pixelation?

Not with the pixels themselves — we replace them with mosaic blocks at export time using Sharp, a destructive re-encode, not a reversible CSS filter. Still, coarse pixelation of a small, low-detail region has occasionally been reconstructed in research settings. For a plate, a generous block size — or Solid fill — is the maximum-safety choice.

Do you keep my car photos?

No. Uploads live in private S3 for up to one hour then auto-delete. We never share with third parties beyond the cloud vision API that runs the plate detection.

Does it work on number plates / car number plates (UK, India, Australia)?

Yes — "license plate", "number plate", "registration plate" and "car number" are the same thing to Blurify. Detection works best on plates that face the camera; oblique angles or stacked multi-line plates are harder, and the draw-your-own-region tool covers those.

Should I blur my number plate when selling a car online?

It's the classic case for blurring a plate at all. A readable plate on a marketplace listing can be cloned onto another vehicle or looked up on registration-data sites — and the listing already tells strangers roughly where the car lives. Blur the plate in every listing photo; if you shot a whole set, Bulk blur does the folder in one pass.

I have a whole folder of car photos — one by one?

No — Bulk blur takes a folder, runs the same plate detection over every photo, and hands back a single ZIP. See the Bulk page.

Does it work on video?

No — Blurify is an image tool. For a video, export the frames you plan to share as images and blur those.

Two parked cars with both license plates (number plates) auto-blurred — Blurify result — Google Cloud Vision finds every plate — shown blurred here; a solid block is the default style.

How it works for plates.

Drop the car photo
Rear, side, or front. JPEG / PNG / WebP / HEIC/HEIF up to 20 MB. We re-encode the export to your chosen format.
Plate region appears
Google Cloud Vision Object Localization detects 'Vehicle registration plate' as a class. You see a tight box around it. Adjust it if the bbox is off — it's a draggable rectangle.
Fill, pixelate, or blur — export
A solid block is the default for plates (irreversible — the pixels are gone). Or pick pixelate / gaussian / color overlay / a sticker. Download with EXIF stripped.
