Frequently Asked Questions
Is this safe for sensitive documents and IDs?
Absolutely. Everything runs strictly in your computer's browser memory using local canvas filters. No image is ever uploaded to any cloud server.
Can a blurred face be unblurred by someone else?
No. Once the pixels are blurred and saved as a new JPEG, the original underlying pixel data is permanently replaced with mathematical gaussian averages.
