File size makes compression decisions easier
A video may be too large because it is long, high resolution, high bitrate, or all three. This checker gives quick local context before you choose a compression setting.
Best settings and limits
Best first try
Choose a video and run the local check. If the file is too large, open the compressor or a target-size page next.
When this may fail
The bitrate is estimated from total file size and duration. Exact stream data can vary by container and track.
Privacy boundary
The selected video file stays on your device while the tool creates the output.
Frequently asked questions
Does this upload my video?
No. The browser reads basic information from the selected local file.
Can it tell me why the file is large?
It shows size, duration, resolution, and estimated bitrate so you can decide whether to compress, resize, or trim.
Will it change the video?
No. This checker only reads information; it does not create a new file.
