    This tool runs entirely in your browser — files never leave your browser.

    How it works

    1. Your video file is loaded into a hidden player element in your browser — it’s never uploaded.
    2. The browser reads the file’s headers directly: duration, pixel dimensions, container type, and file size. Bitrate is estimated from file size ÷ duration (exact bitrate needs a full file scan, which this tool skips to stay instant).
    3. A codec-support panel tests which video codecs (H.264, HEVC, VP9, AV1) your browser can play, then the whole report is shown in a table you can copy as JSON, CSV, or plain text.

    Everyday uses

    • Video creators — check a recording is actually 1080p/4K before uploading to YouTube.
    • Web developers — verify codec support so embedded videos play for your visitors.
    • Marketers — confirm duration and size limits before posting to social platforms.
    • Troubleshooting — a video that won’t play often has an unsupported codec; this tool shows you which ones work.
    • Archivists — quickly catalog a folder of videos with copy-paste metadata.

    FAQ

    Is the bitrate exact? It’s an estimate (file size ÷ duration). True bitrate requires scanning the whole file, but the estimate is accurate enough for judging quality and upload size.

    Why doesn’t it show the exact codec of my file? Browsers expose container and dimensions from headers, but not the internal codec string, without decoding the whole file. The tool shows what your browser can decode instead, which answers the more practical question: “will it play?”

    Which formats can I check? Any video your browser can open: MP4, WebM, MOV, OGG, and MKV in most browsers.

    Is my video uploaded anywhere? Never. The file is read locally from your device — files never leave your browser.
