FAQ: Download FB Video to MP3
1. Can FvidGo download audio from Messenger?
No. Facebook officially does not provide externally accessible sharing links for private voice messages or audio in Messenger. FvidGo needs valid public links for parsing, so it cannot access and download audio files from within Messenger.
2. Can FvidGo download audio from Facebook Watch?
Yes. FvidGo perfectly supports parsing and extracting video audio from Facebook Watch. You simply need to copy the link of the target Watch video, paste it into the top input box, and you can quickly convert it to MP3 format.
3. Where are the downloaded MP3 files saved on my device?
Usually, files are saved in your browser's default download path. You can click the "Settings" or "Menu" icon (usually three dots or three horizontal lines) in the upper right corner of the browser, find and click "Downloads", and you will see the audio file you just downloaded. If you are on a mobile device, you can usually find it in the system's "File Manager" or "Downloads" folder.
4. Can FvidGo be used directly on an iPhone or Android phone?
Yes, absolutely. FvidGo is a pure web-based online tool with excellent cross-device compatibility. Whether you are using an iPhone (iOS) or Android phone, simply open the browser on your phone (such as Safari or Chrome) to visit this site, and you can Facebook video download audio directly without installing any App.
5. Can I use FvidGo to convert any Facebook video to MP3?
This depends on whether the video itself contains audio data. If the original video has sound, FvidGo can successfully extract the audio for you; but if the video itself is purely muted (i.e., contains no audio track), FvidGo cannot magically convert an audio file out of nothing.
6. Are there any limits on daily downloads or converted video length?
There are no limits at all. FvidGo is committed to providing a 100% free and barrier-free experience. You can download an unlimited number of audios anytime, anywhere, and even hours-long Facebook live replays or ultra-long videos will not be hindered by any count or duration limits.
