FAQ

Specific answers for this tool, not generic converter copy.

Does checking file size upload the file?

No. The browser can read basic file details locally.

What is estimated bitrate?

It is file size divided by duration. Container overhead means it is an estimate, not an exact codec report.

Why inspect audio before compressing?

Size, duration, and bitrate help you choose whether compression is worth it.
