Frequently Asked Questions (FAQ)

Q.Why does conversion speed vary by device?

Our tool uses your computer's CPU instead of a remote server. Newer, high-performance CPUs process the complex math much faster, resulting in quicker conversions.

Q.Can I convert large video files?

Yes, but if the file exceeds your browser's available memory, the process might freeze. We recommend avoiding files larger than 1GB.

Q.How is the sound quality of the resulting MP3?

We maintain the maximum possible quality from the original video's audio track by applying standard high-quality VBR encoding settings.
