Estimate your video file size
Use duration and bitrate to plan a smaller sharing copy. No upload or account.
Example: one minute at 8 Mbps video and 128 kbps audio is about 60.96 MB, before container overhead.
Estimate only: duration × combined bitrate ÷ 8. MB uses 1,000,000 bytes; MiB uses 1,048,576. Container overhead and variable bitrate can change the exported size. Leave a margin for upload limits. This tool does not compress, upload or delete files.
