Frequently Asked Questions
Is blurring or pixelating faces in this tool mathematically irreversible?
Yes. The blur and pixelation algorithms destroy the high-frequency pixel data in the canvas memory by averaging pixel clusters into single color values. Because this is a destructive, one-way mathematical operation, the original facial features cannot be recovered from the exported image.
Can I blur car license plates and credit card numbers with this tool?
Yes. You can use the manual rectangular selection or brush tool to apply blur or pixelation over vehicle license plates, credit card numbers, house addresses, or private documents.
What is the difference between Gaussian Blur and Pixelation (Mosaic)?
Gaussian Blur applies a convolution filter that smooths pixel transitions according to a bell curve distribution, creating a soft, out-of-focus effect. Pixelation divides the selected area into coarse pixel blocks, creating a classic mosaic censor effect.
Are my private photos uploaded to any AI server or cloud storage?
No. All image processing and pixel manipulation execute entirely inside your local browser via HTML5 Canvas. Your images are never transmitted or stored on any server.
