🫥 Blur faces and sensitive data
How it works in your browser
Each area you mark is blurred on a canvas in the browser and the blur is then baked permanently into the exported pixels - there is no separate hidden layer that could be peeled back. Everything happens on your device, so the sensitive image is never uploaded.
Choosing a format
Export as PNG to keep the rest of the image sharp and lossless. Because the blur is flattened into the file, the obscured detail is genuinely gone in the copy you download and share.
Example
For example, before posting a photo of a parcel you can drag a box over the shipping label and a box over a bystander's face, raise the blur strength, and download a version where both are unreadable.
How to blur faces & data
- Drop a photo.
- Drag across the parts you want to hide (add as many as you like).
- Adjust blur strength and download the PNG.
FAQ
Are my images uploaded to a server?
No. Every operation runs entirely inside your browser using WebAssembly and on-device models. Your files never leave your device and are never sent anywhere. You can even disconnect from the internet after the page loads.
Can the blur be reversed?
No. The blur is baked into the exported pixels, so the original detail is permanently gone in the downloaded file.
