🔎 Video Metadata Viewer
See everything inside a video file — resolution, codec, frame rate, bitrate, audio and hidden tags like the creation date, device and GPS. Free, instant & 100% private, right in your browser.
Inspect everything inside a video file — resolution, codec, frame rate, bitrate, audio details and hidden metadata tags. Nothing is uploaded; it all reads in your browser.
Look Inside Any Video
From codec and bitrate to the metadata most tools never show you — without uploading a thing.
Resolution & FPS
Exact width, height, aspect ratio and frame rate, shown the moment you drop a file in.
Codec Detection
Identify the video and audio codecs — H.264, HEVC, VP9, AV1, AAC, Opus and more.
Bitrate Breakdown
A visual split showing how much data goes to the picture versus the sound.
Hidden Tags
Reveal creation date, encoder, device make/model and even GPS — if the file stores them.
Smart Insights
Total frames, megapixels per frame, data-per-minute and the real compression ratio.
100% Private
Everything is read in your browser with ffmpeg — nothing is uploaded or stored.

Frequently Asked Questions
Codecs vs containers, what bitrate means, the GPS/creation tags, compression ratio, formats and privacy.
How do I check a video's details?
Just drop your video in. The basics — resolution, duration and aspect ratio — appear instantly from your browser, and a deeper read (codec, bitrate, frame rate, audio, container and any embedded tags) follows a moment later. Nothing is uploaded; the whole analysis happens on your device.
What is a codec, and why does it matter?
A codec is the method used to compress and decompress the video and audio inside the file — H.264, H.265 (HEVC), VP9 and AV1 are common video ones; AAC and Opus are common for audio. It matters because it decides how widely your file will play and how small it is. An older device might not support a newer codec like AV1, which is exactly the kind of thing this viewer helps you check.
What's the difference between a codec and a container (like MP4)?
The container — MP4, MOV, WebM, MKV — is the box; the codec is what's inside it. An '.mp4' file is just a wrapper that can hold video encoded with H.264 or H.265 and audio encoded with AAC or others. That's why two MP4 files can behave completely differently: same box, different contents. This tool shows you both.
What does bitrate tell me?
Bitrate is how much data the video uses per second, usually in kilobits per second (kb/s). Higher bitrate generally means better quality and a larger file. The viewer breaks it down so you can see how much of the data goes to the picture versus the sound — often the video is more than 95% of it.
Can it show when and where a video was filmed?
If the file contains that information, yes. Many videos store a creation date, the encoder or app that made them, the device make and model, and sometimes GPS coordinates — all in metadata tags. This viewer surfaces whatever tags are present. (If you'd rather strip that information out before sharing, that's a privacy step worth knowing about.)
Is my video uploaded to a server?
No. The file is read entirely in your browser using ffmpeg compiled to WebAssembly — it never leaves your device, nothing is stored, and there's no sign-up. That's especially important for metadata, which can include personal details like location.
What's the 'compression ratio' insight?
It's a fun, computed comparison: how big the video would be completely uncompressed (every pixel of every frame stored raw) versus its actual file size. The result is often hundreds of times smaller — a quick illustration of just how much work the codec is doing behind the scenes.
Which file types work?
MP4, MOV, WebM and MKV are the main ones, and most other common video formats will read too. The viewer reports whatever the file actually contains, so it's a quick way to confirm an unfamiliar file's real format.
