About this tool
Estimate a video file size free in your browser from video bitrate, audio bitrate and duration. Nothing is uploaded; bytes and mebibytes are calculated on your device. Container overhead and variable bitrate are ignored, so treat the figure as a planning sketch.
Privacy & limitations
Ignores container overhead and VBR swings. It estimates from bitrate times duration only.
