Audio Anonymization FAQ
How does AI audio anonymization and voice masking work?
Our AI analyzes the audio track of your video to detect speech patterns, voices, and sensitive keywords. It then applies intelligent distortion, masking, or muting techniques to protect identities while maintaining audio quality and conversation flow.
Can I blur moving objects in a video automatically?
Yes, BGBlur's AI automatically tracks moving objects, faces, and vehicles. You do not need to manually mask every frame; the motion-aware tracker keeps the blur locked onto the subject as it moves.
How do I pixelate faces online without installing software?
BGBlur is a completely web-based tool. You can upload any video or image, select the Face Blur tool, and apply pixelation or blur instantly inside your browser without downloading any apps or plugins.
Is it possible to auto-blur license plates in dashcam videos?
Absolutely. Our AI is trained specifically to detect and blur license plates in driving footage, dashcams, and street-view videos. It helps creators and transport fleets stay compliant with privacy laws.
Does BGBlur upload my private videos to a remote server?
Your privacy is our priority. BGBlur leverages advanced client-side technologies to process videos securely. Your files are processed locally in your browser and are never uploaded or stored permanently on external servers.
Can I blur a video background on iPhone, Android, or mobile devices?
Yes! BGBlur is fully responsive and optimized for mobile browsers. You can easily blur a video background or pixelate faces directly on your iPhone, iPad, or Android phone.
What is the maximum video file size and duration supported?
Limits depend on the feature. Standard video blur tools such as face blur, license plate blur, background blur, blur anything, screen blur, NSFW blur, and face anonymization support up to 200MB and 10 minutes on the free plan, while Pro users get unlimited blur processing with longer video support. Object Remover supports MP4 and MOV videos up to 1GB and 10 seconds per clip.
