Media Info
Open a video or audio file to see everything inside it: codecs, resolution, frame rate, bitrate, colour, tags, chapters and location. The file is read on your device and never uploaded.

About Media Info
This free media file inspector shows what is really inside a video or audio file: the container (MP4, MKV, WebM…), the codecs and their profile, the resolution and frame rate, the bitrate, the colour space and HDR, the sound format, and the descriptive tags. It works like the well-known MediaInfo program, without installing anything.
It is useful to understand why a video does not play on a TV, why a file is so large, whether a phone video is HDR, or what an export really contains before sending it.
Key Features
- General: container, MIME type, duration, overall bitrate, creation date, writing application.
- Video: codec in plain words and codec string (e.g. avc1.640028), profile and level, resolution, display aspect ratio, rotation, frame rate, bitrate, bit depth, colour primaries, transfer function, HDR, key frame interval.
- Audio: codec, sample rate, channels, bit depth (WAV, FLAC), MP3 mode (CBR / VBR).
- Metadata: title, artist, album, date, comments, cover art, chapters (MKV, MP4) and GPS location.
- Export: copy the report as text, or download it as .txt or JSON.
How to Use the Tool
- Step 1: drop a file on the area above, or click to choose one.
- Step 2: read the cards: General, Video, Audio, Location, Tags, Chapters.
- Step 3: check the Location card before sharing a phone video.
- Step 4: copy the report or export it as text or JSON for a ticket, a forum or a script.
Common Use Cases
- Checking that a video meets the specifications of a platform, a broadcaster or a client (codec, resolution, frame rate, bitrate).
- Finding out why a TV, a car radio or an old phone refuses a file (HEVC, 10-bit, unusual sound codec).
- Checking the tags and cover art of an MP3 or FLAC music library.
- Making sure a video does not reveal where it was filmed before posting it.
Tips & Best Practices
- Large files: only the headers and indexes are read, so a 10 GB film is analysed in about a second. For MKV and WebM, stream bitrates are estimated.
- Rotation: phone videos are often stored landscape with a rotation flag; the resolution shown is the displayed one, and the coded size is listed when it differs.
- Location: phones and cameras can write GPS coordinates into videos. Re-exporting with the video compressor or the video cutter removes them.
- AVI files are read with a built-in RIFF parser; very old or unusual codecs are shown with their FourCC code.
Privacy & Security
The file is read only by your browser, piece by piece: it is never uploaded, stored or analysed on a server, and the tool makes no network request. The “Open in OpenStreetMap” link only opens a map if you click it. Reading video and audio containers relies on Mediabunny 1.62.1, distributed under the Mozilla Public License 2.0 and served from this site.
