What this report does not guess
Browsers do not reliably expose codec, frame rate, color profile, GPS, or camera tags. The bitrate is an estimate from total bytes and duration, so it includes every stream in the file.
What your browser can actually tell you
Duration, the playable width and height, the aspect ratio those imply, the file size, the type the file reports, and when it was last modified. Those are read directly and are reliable.
The bitrate is the one derived number: total file size divided by duration. It is an average across the whole file, not a stream property, so it is useful for "is this roughly a 5 Mbps file" and wrong for anything that varies its rate — which is most modern encodes.
Why the codec is not listed
A browser will tell you it can play a file without telling you what is inside it. There is no reliable path from a video element to the codec, the profile, the chroma subsampling or the exact container variant.
So this page reports what can be verified and stops. A viewer that guessed at the rest would be more satisfying and occasionally wrong, which is the worse trade for a tool people use to answer a factual question.
The most useful answer here is often "it opens"
If this page reads your file, a browser can decode it — which means every other tool on this site can work with it. If it cannot, that is the answer you needed, and usually means HEVC or ProRes.
That makes this the first stop when a conversion fails somewhere else. Rather than guessing at why, drop the file here: either the details appear and the problem is elsewhere, or nothing does and the file needs re-exporting as H.264.
The report copies as text
One button puts the whole readout on the clipboard as plain text, which is what you want when the reason you are looking is that someone asked you what the file is.
It pastes into a ticket, a chat, or an email without a screenshot, and it stays searchable afterwards.
Nothing is uploaded
The file is read on your own machine and the details are drawn in this tab. No account, no upload, nothing stored.
Inspecting a file is exactly the moment you have not decided whether it can be shared yet, so a tool that required you to upload it first would be asking the question backwards.
- Can this identify every codec?
- No. Browser APIs reliably expose playable dimensions and duration, but not every container or codec field. The page reports what can be verified rather than guessing at the rest.
- How is bitrate calculated?
- Total file size divided by duration — an average across the whole file, not a stream property. Good for a rough magnitude, wrong for anything with a variable rate, which is most modern encodes.
- My file will not open here. What does that mean?
- That your browser cannot decode it, which is the same reason it would fail in the other tools on this site. It is almost always HEVC (H.265) or ProRes; re-export as H.264 and everything works.
- Can I get the details as text?
- Yes, one button copies the whole readout to the clipboard as plain text — for pasting into a ticket or a message instead of attaching a screenshot.
- Does the file upload?
- No. It is read on your own machine and the details are shown in this tab. Which matters here in particular: inspecting a file is the moment before you have decided whether it can be shared.
