Check Video File Size
Read a selected video’s storage size and use it for transfer or storage planning.
Practical Example
A 750 MB video requires roughly 0.75 GB of decimal storage before copies or backups.
Factors That Affect the Result
Codec, bitrate, duration, resolution, audio tracks and container overhead determine file size.
Frequently Asked Questions
Does this compress the file?
No.
Are MB and MiB identical?
No. Decimal and binary units differ.
Is the video uploaded?
Local browser checks do not require upload.

Checking Video File Size
File size is useful for upload limits, storage planning and transfer estimates, but it does not measure visual quality by itself. Two videos with the same duration can differ greatly in size because of codec, bitrate, resolution, frame rate and audio settings. Compare files only when those production settings are reasonably similar.
Technical Details and Limitations
Video file size reflects all stored streams and container overhead, including video, audio, subtitles and metadata. Bitrate × duration gives an estimate, but variable bitrate and muxing overhead mean calculated and actual sizes may differ.
