About Video Metadata Viewer
The Video Metadata Viewer allows you to inspect comprehensive technical and file properties of any video stored on your device directly in your web browser. Utilizing native HTML5 File and Media APIs, the tool determines exact frame dimensions (width and height), calculates standard aspect ratios (e.g., 16:9, 9:16, 4:3, 1:1), identifies video orientation (landscape, portrait, or square), classifies the resolution category (4K UHD, 1080p Full HD, 720p HD, etc.), and computes duration down to the second alongside file size and approximate container bitrate. Processing occurs 100% client-side in your browser with zero server uploads, keeping your video files completely private and secure.
How to Use Video Metadata Viewer
- 1Choose a video file from your computer or mobile device, or drag and drop it into the upload box.
- 2The browser extracts and calculates all video stream properties immediately.
- 3Review the structured metadata dashboard organized into File Info, Video Stream, and Technical specs.
- 4Use the built-in preview player to verify the video playback or check specific timestamps.
- 5Click "Copy Metadata" or "Export JSON" to save the extracted properties to your clipboard or notes.
- 6Click "Choose another video" or "Remove video" to inspect a different file at any time.

🔒 Privacy First — Your Data Never Leaves Your Device
Your privacy is our highest priority. The Video Metadata Viewer tool processes all your files and data entirely within your web browser using modern JavaScript and WebAssembly technology. No files, images, documents, or personal information are ever uploaded to our servers or transmitted over the internet. This means your sensitive data stays completely private, secure, and under your control at all times — even if you are offline after the page has loaded.
Frequently Asked Questions
What is video metadata?
Video metadata encompasses information embedded in or associated with a video file, such as its container format, pixel dimensions (width and height), display aspect ratio, playback duration, file size, and creation/modification timestamps.
Does this tool upload my video to a server?
No. The Video Metadata Viewer processes your video locally within your web browser using HTML5 File and Media APIs. Your video data remains entirely on your device and is never transmitted to an AllAdvanceTools server.
How does the tool calculate aspect ratio and orientation?
Once the browser decodes the video stream header, the tool extracts the native videoWidth and videoHeight. It then calculates the greatest common divisor (GCD) to determine the mathematical aspect ratio and compares dimensions to identify whether the video is Landscape, Portrait (e.g. smartphone vertical video), or Square.
Can I see the exact video codec used in the file?
Standard web browser APIs expose video container MIME types and stream properties, but do not provide raw elementary stream codec headers (such as specific H.264 profile levels or audio bit depth) without heavy native demuxers. The tool accurately indicates when detailed codec information is not exposed by your browser.
Which video file formats are supported?
The tool supports all video formats compatible with your browser's native media engine, including MP4, WebM, Ogg, and MOV (on supported browsers and operating systems).
Can I copy or export the extracted metadata?
Yes. You can use the "Copy Metadata" button to copy a formatted text summary or the "Export JSON" button to copy structured JSON data to your clipboard for use in documentation, scripting, or video production workflows.
