Blur a license plate

Selling a car, posting a parking dispute, sharing a photo of a near miss — all of them put a license plate in front of strangers.

A plate is a lookup key. In a fair number of places it can be turned into a name and an address, legitimately or otherwise, and it is unique to one vehicle in a way that a photograph of a street is not.

Works today, in your browser. Photos open in the editor and Word documents are checked for hidden data; either way the file is read on your device and never uploaded.

How it finds the plate

By reading the text in the picture and checking it against the shapes license plates take — the letter-and-digit patterns used across a number of countries. A string that looks like a plate gets its own switch and its own count.

It is more reliable on a plate facing the camera and in focus than on one at an angle or in motion. When it misses, drag a box over it: that takes three seconds and is the whole job.

A solid box, every time

Plates default to a solid fill, not a blur. The character set is tiny, the font is standardized by law, and the position of each character is predictable — which makes a blurred plate one of the easier things to recover. A filled rectangle is not.

The other thing in that photo

A photograph of a car almost always says where the car was. The coordinates are in the file, written by the phone, and they are frequently the seller’s own driveway.

The copy you download from here has no coordinates, because the picture is drawn again from scratch. Covering the plate and leaving the location in would be an odd place to stop.
