Read video dimensions, duration, and file size.
Inspect a local video before uploading or sharing. Your browser reads the media metadata without sending the file to a server.
Inspect a video before sending it to a platform that specifies resolution, duration, or file-size limits. Compare the reported values with that platform's requirements. This tool reports the file; it does not transcode or resize it.
Identify the length and dimensions of clips when planning an edit or reviewing a folder of exports. The browser loads metadata and offers playback so you can confirm you selected the intended file.
Supported containers and codecs vary by browser. Frame rate and codec names are not exposed reliably by this tool.
A playable 1920 × 1080 local video with a duration of 42.5 seconds.
Its native dimensions, duration in seconds, file size, and available media type.
The reported media type comes from browser file information and may be blank or generic. It is not a full codec analysis.
A familiar extension can still contain a codec your browser does not support. Try a playable MP4 or WebM file, or check the source in a compatible media player.
Wait for the browser to read the file. Damaged files, unusually structured containers, or unsupported encoding can prevent a usable duration or frame size from being reported.
A little clarity before you get started.
No. A file must use a container and codec your browser can play.
No. This tool focuses on duration, dimensions, file size, and the browser-reported media type. Those values should not be treated as a complete technical inspection of the encoded streams.
No. The browser loads a local object URL for the selected file. The video bytes are not sent to the PHP account server for analysis.
No. The tool inspects and plays supported files. Changing a container, codec, bitrate, or resolution requires a separate video conversion or editing tool.
Desktop players and browsers can support different containers and codecs. A file that works in one player is not guaranteed to be decodable by the browser and operating system you are using.
No. This tool is free to use without signing in. An account lets you keep a list of favorite tools.
Yes, with a current browser. File support, download behavior, and available memory vary by device. For large documents and images, a computer is often more comfortable.
