Frequently Asked Questions
Does this use AI to detect sensitive content?
Not automatically. You manually select which areas to blur, giving you full control over what gets hidden. This is intentional — only you know what is sensitive.
Can I undo a blur region?
Yes. Click on a blur rectangle to select it, then click "Remove" or press Delete to remove it. You can also clear all regions with one click.
Is the blur reversible?
No. The pixelation effect destroys the original pixel data in the blurred area. For maximum security, use the original image as your source of truth.
What image formats are supported?
PNG, JPEG, WebP, and BMP. Output is always PNG to preserve the blur effect without re-compression artifacts.
