Frequently Asked Questions (FAQs)
Q: Are blurred faces permanent and irreversible in the downloaded image?
A: Yes! Once exported, the blurred pixel data permanently replaces the original pixels on the canvas, ensuring complete, irreversible privacy protection.
Q: What is the difference between Gaussian Blur and Pixelate?
A: Gaussian Blur creates a smooth, frosted glass effect that softens facial contours, while Pixelate (Mosaic) turns features into stylized blocky squares. Both provide total anonymization.
Q: Can I blur license plates, house numbers, or private text?
A: Yes! You can click and drag custom rectangular censor boxes anywhere on the image to redact vehicle license plates, ID numbers, sensitive addresses, or timestamps.
Q: How does Auto Face Detection work?
A: Our tool uses hardware-accelerated client-side Face Detection to automatically find faces in your picture and place blur boxes over them with one click.
Q: Are my photos uploaded to any external server?
A: No! Face detection and pixel censorship algorithms run 100% locally inside your web browser memory. Your images never leave your computer or phone.
