Frequently Asked Questions
How much blur do I need to hide faces?
For effective face anonymization, use a blur amount of 10px or higher. The higher the blur value, the less recognizable the face becomes.
Can I blur only part of an image?
This tool blurs the entire image. For selective blurring of specific areas, use a photo editor like Photoshop or GIMP with layer masks.
What type of blur does this tool use?
We use Gaussian blur, which creates a smooth, natural-looking blur effect similar to looking through frosted glass.
