When it comes in handy
For example, it helps when you need to pixelate a bystander's face and a license plate before posting a photo to social media.
It is also handy for blurring names or ID numbers before sharing a document image.
Only what you brush is hidden
Only the areas you brush get blurred or pixelated, and you can undo stroke by stroke. Hidden areas are actually blurred, so the original content can't be made out.
Processed on your device
The image is never sent to a server; it's processed inside your browser, so sensitive photos stay private.
