Private
The file is read on your device; only the header is analysed, so even large files show results in a second or two.
Good to know
Only the file header is read, so results appear in a second or two even for large files. The technical report shows every stream exactly as FFmpeg sees it.
Supported files
Any common audio or video file: MP4, MOV, MKV, WEBM, AVI and other video formats, and MP3, WAV, M4A, FLAC, OGG, OPUS, WMA and other audio formats. Files up to 1 GB each.
Frequently asked questions
What does "hevc" mean?
HEVC (H.265) is a newer video codec. If a device cannot play the file, convert it to MP4 with "Play everywhere" ticked.
Do I have to pay or sign up to use the Media Info?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Are my files safe?
Yes. Files are converted locally in your browser and are never uploaded. When you close the page, nothing is left behind.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
