Frequently asked questions

Which audio and video formats are supported?
Most common containers and codecs, including MP4, MKV, MOV, AVI, WebM, MP3, WAV, FLAC and AAC. The tool reports whatever tracks the file contains.
Why does my video play on one device but not another?
Usually because of the codec. This viewer shows the exact video and audio codec, so you can confirm whether a device or player supports it before re-encoding.
Can it read very large video files?
Yes. It only reads the parts of the file that describe its structure, so even multi-gigabyte videos are inspected almost instantly without loading the whole thing.
Is my file sent to a server?
No. Everything runs locally in your browser. Your file is read and processed on your own device, nothing is uploaded, and nothing is logged or stored.
