Video Metadata Viewer
See everything a video file says about itself. The viewer lists the container tags – title, artist, creation date, recording device, GPS location, software – the details of every video, audio and subtitle stream, and the chapters. Tags that can reveal when, where or with which device a video was recorded are highlighted, and the full report can be downloaded as JSON.
- Files stay on your device
- No sign-up
- Free to use
Metadata
Shows every tag stored in the file – creation date, device, location, encoder, titles, chapters – and the details of each stream.
Processing happens on your device with FFmpeg. Keep this tab open; long or high-resolution videos can take several minutes.

Video Metadata Viewer FAQ
Which metadata do phones store?
Typically the creation time, the GPS location (if location access is on for the camera), the make and model of the phone and the software version.
Can I see where a video was filmed?
If the file contains a location tag, the coordinates are shown. Many apps remove it when sharing, but files copied directly from a phone usually keep it.
Does it work with audio files?
Yes. MP3, M4A, FLAC, OGG and WAV tags are shown too.
How do I remove the metadata?
Use the Video Metadata Remover, which copies the streams without re-encoding and strips the tags.
Why does the first run take longer?
The media engine, FFmpeg compiled to WebAssembly (about 32 MB), is downloaded once and then cached by your browser.
Is my video uploaded?
No. FFmpeg runs as WebAssembly in your browser, so the video stays on your device.
What video files reveal
Video files carry metadata alongside the picture and sound. Some of it is technical – the codec, the frame rate, the brand of the container. Some of it is personal: the date and time of recording, the device that recorded it and, on phones, often the precise location. When videos are shared as files, all of this travels with them.
The viewer reads the container with FFmpeg and lists every tag exactly as stored. Location tags in the ISO 6709 format, such as +40.7128-074.0060/, are decoded into latitude and longitude. Tags commonly associated with personal information – dates, locations, device makes and models, software names, authors – are collected into a privacy summary at the top.
Each stream has its own metadata: language codes, handler names, encoder strings and titles. Chapters are listed with their start and end times and titles. Together this gives a complete picture of the file’s structure and history.
For journalists, archivists and anyone verifying footage, the JSON export documents the metadata at the time of checking.
Metadata can also help you: creation dates sort clips from different cameras into the right order, and encoder tags show which program last exported a file, which is useful when tracking down playback problems.
Files are read locally and are not uploaded.
