See everything a media file says about itself

Drop in a video or audio file and the viewer lists what is stored inside it: the container, the length, every video, audio and subtitle stream with its codec, size and bitrate, and all the tags, including any location, device and date the file reveals. Only the file's header is read, on your own device, so nothing is uploaded.

What it reads

A media file is a container holding one or more streams. The viewer shows the container type, the duration and overall bitrate, and for each stream its type, codec, profile, picture size, frame rate, sample rate, channel layout and bitrate where the file states them. It also lists the tags and any chapters. Because only the header is read, even a very large file is reported quickly.

Check before you share

Videos from phones and cameras often carry the date they were recorded, the make and model of the device and sometimes the GPS position. The viewer highlights these in a panel at the top and prints coordinates in plain language. If you would rather not send them on, remove video metadata makes a copy without them, with the picture and sound untouched.

Reading the codec

H.264 plays on almost everything. HEVC, also called H.265, makes smaller files at the same quality but is not supported everywhere. VP9 and AV1 are modern formats used on the web. For sound, AAC and MP3 play almost everywhere and Opus is common in WebM files. If a file will not play on a device, its codecs here usually explain why, and the video converter can change them.

Rotation, size and unknown lengths

Phones often record in landscape and store a rotation flag. The viewer shows the stored size, such as 1920 × 1080, and how it is displayed once the flag is applied, such as 1080 × 1920. Files recorded straight in a browser, such as WebM from a screen recorder, often do not store their duration, and the viewer says so instead of guessing. To plan a file size from a bitrate, use the video bitrate calculator.

Frequently asked questions

How do I check the codec of a video?
Drop the file into the box. The Streams table lists each stream with its codec, for example h264 for the picture and aac for the sound, together with the resolution, frame rate and bitrate.
How can I see a video's resolution and frame rate?
They are in the Streams table, on the video row: the picture size in pixels, such as 1920 × 1080, and the frames per second. If the file carries a rotation flag, the viewer also shows the size as it will be displayed.
Does this show GPS location in a video?
Yes, when the file stores one. The panel at the top reports the location tags in plain language, for example 12.3456° N, 78.9012° E, and warns you before you share the file. If there are no location tags it says so.
What is the rotation flag?
A note in the file that tells players to turn the picture when showing it. Phones use it so they can always record in the same direction. A flag of 90° or −90° means a 1920 × 1080 recording is displayed as 1080 × 1920.
Why does the duration say it is not stored in the file?
Some files, especially WebM recorded directly in a browser, do not write their length into the header. The viewer reports that instead of guessing. The file still plays, and converting it once with the video converter writes the duration in.
Can I edit the metadata here?
No, this tool only reads it. To remove tags, location and device information, use remove video metadata, which makes a clean copy without re-encoding.
Which files can it read?
Common video and audio formats, including MP4, MOV, MKV, WebM, AVI, MP3, WAV, M4A, FLAC and Opus. If a file cannot be read as media, the viewer tells you.
Is my file uploaded, and is it free?
Nothing is uploaded. Only the start of the file is read, on your device, using a WebAssembly build of FFmpeg that is downloaded once. The viewer is free, with no account and no limit.
