What this tool tells you
Drop in any video your browser can open and you get the essentials in a second: resolution, aspect ratio, duration, file size, the average bitrate across video and audio, and a measured frame rate. It is the quick check you need before uploading to a platform with limits, before choosing export settings, or when a client sends a file and you want to know what you are dealing with.
How the numbers are worked out
Resolution and duration come straight from the browser's video decoder. The average bitrate is the file size in bits divided by the duration, so it includes audio and container overhead. That makes it ideal for estimating streaming bandwidth or storage, and you can turn it into sizes for other lengths with our bitrate calculator. The frame rate is measured by playing a short stretch and counting decoded frames, which gives a reliable estimate for most files.
When you need more detail
For codec profiles, colour information, HDR metadata or per-track bitrates, a desktop tool such as MediaInfo or ffprobe goes deeper. For most everyday questions, such as "is this 1080p?", "why is this file so large?" or "is it 30 or 60 frames per second?", this viewer answers in seconds. If the file is too large for your needs, the video compressor and our guide on compressing without losing quality are the next step.
Frequently asked questions
Is my video uploaded?
No. The file is opened locally by your browser. Nothing is sent to any server.
Why does it say the browser cannot play my file?
The file uses a codec your browser cannot decode, such as HEVC in Firefox or ProRes in most browsers. Size and type are still shown, and the codec checker can tell you what this device supports.
How accurate is the frame rate?
It is measured by watching a short stretch of playback, so it is a close estimate. Variable frame rate phone videos may show a value slightly below the nominal rate.
