FAQ
Why is the browser asking for camera and microphone permissions?
Web browsers require explicit user permission before any website can access your camera and microphone. This is a security feature that protects your privacy. Click "Allow" to grant permissions. The tool needs camera access for video and microphone access for audio recording. Everything only works while the page is open and never uploads your video, audio, or photos.
How do I switch between cameras?
If you have multiple cameras (like front and back cameras on a laptop), use the camera device dropdown at the top. Select the camera you want to use and the tool will switch to it immediately.
What filters are available?
The tool includes 8 filter presets: None (original), Grayscale (black and white), Sepia (vintage brown tone), Invert (negative effect), Blur (soft focus), Vintage (aged photo look), Cold (blue tone), and Warm (orange/yellow tone). You can also manually adjust brightness, contrast, saturation, and blur.
Are my photos and videos saved anywhere?
No. All processing happens entirely in your browser. Photos and videos are only stored temporarily in your browser memory. When you download them, they are saved to your local device. Nothing is ever uploaded to any server.
What is the grid overlay for?
The grid overlay displays a rule of thirds composition guide - a photography technique that helps create balanced and visually appealing photos. Position important elements along the grid lines or at their intersections for better composition.
Why is my camera quality lower than expected?
Camera quality depends on several factors: your hardware camera specifications, browser implementation, lighting conditions, and any applied filters or zoom. Try testing in good lighting, removing filters, and ensuring your camera drivers are up to date. Some browsers may limit resolution for web applications.
Can I use this to take professional photos?
While the tool provides high-quality captures and creative filters, it is primarily designed for testing cameras and creating casual photos. For professional photography, dedicated camera applications with RAW support and advanced editing capabilities are recommended.
What video format is used for recording?
Videos are recorded in WebM or MP4 format (depending on browser support) at 60 fps with audio. The recordings use high-quality settings with 10 Mbps video bitrate and 128 kbps audio bitrate for excellent quality. Both formats provide good compression and are widely supported in modern browsers and media players. If you need a different format, you can convert the downloaded file using video conversion tools.
