Frequently asked questions
Everything you need to know about vid2audPro.
Is vid2audPro really free?
Yes — completely free. No signup, no watermarks, no daily limits.
Are my files uploaded to a server?
No. vid2audPro runs FFmpeg inside your browser using WebAssembly. Your video is processed locally and never leaves your device — which also makes it fast and safe for private footage.
Which video formats are supported?
MP4, MOV, AVI, MKV, WEBM, FLV, M4V, MPEG, WMV and 3GP.
What MP3 quality should I choose?
192 kbps is a great balance for most audio. Pick 320 kbps for music you care about, or 64–128 kbps for voice recordings and lectures to keep files small.
Is there a file size limit?
The app accepts files up to 2 GB. Because conversion happens in your browser's memory, very large files work best on desktop devices with plenty of RAM.
Does it work on mobile?
Yes — vid2audPro is fully responsive and works on Android and iPhone in any modern browser.
