Video Metadata Viewer
See a video's key details — dimensions, duration and format — without uploading the file anywhere.
The facts about a video file
Before you send, post or edit a video, there are a few things worth knowing: how long it runs, what resolution it is, its aspect ratio and format, and roughly how heavy the file is. Rather than open a video editor to check, drop it here and those details are read straight from the file. It is the quick answer to will this fit the upload limit, is this the right resolution, and why is this clip so large.
Useful when a platform caps length or size, or when you are working out why a video is slow to send.
A viewer, not an editor
This reads and reports; it does not change the video. If the details flag a problem — too long for a platform, too large a file, the wrong dimensions — that tells you which fix you need, whether that is trimming, compressing or resizing elsewhere. Crucially, a video can be a big file, so it staying on your device rather than being uploaded to be inspected is the point.
How to view a video's metadata
- Add the video file.
- Read its duration, dimensions, format and other details.
- Use the details to plan a conversion or upload.
Check before you upload
Upload rejections usually come down to a number you cannot see: the resolution, the duration limit, the container format or the file size. Reading the metadata first tells you which one is the problem instead of guessing after a failed upload.
It is also how you check whether a video is genuinely the resolution it claims — an upscaled file reports large dimensions without the detail to match.
Common questions
Why was my video rejected by a platform?
Commonly the resolution, duration, format or file size falls outside their limits — the metadata shows which.
What does the container format mean?
MP4, MOV and similar describe how the video and audio are packaged, which affects compatibility.
Is the video uploaded to read this?
No, the file is inspected in your browser.
What details does it show?
The dimensions, duration, aspect ratio and format of the video, plus its file size.
Does it change or convert the video?
No. It only reads and reports the details; the file itself is untouched.
Is my video uploaded?
No. The details are read in your browser, so even a large video never leaves your device.
