FAQ
Frequently Asked Questions
What is image blur used for?
Blurring hides sensitive information in screenshots, obscures license plates, adds artistic background blur, or prepares images for design mockups.
Is my image uploaded to a server?
No. All blurring happens locally in your browser using the Canvas API. Your images never leave your device.
What formats are supported?
JPG, PNG, WEBP, and GIF are all supported. The output matches your input format.
How strong can the blur be?
The slider goes up to 50px radius — strong enough to make content unrecognizable. The Heavy preset at 25px is suitable for most privacy use cases.
