What this guide covers and when it works — Download FB video to MP3

This guide explains how to download FB video to MP3 for personal, offline use. VidSave Pro saves public Facebook videos only, and it saves them as MP4 video files. You will first save the MP4, then extract the audio to MP3 using a separate converter.

Key limits:

  • Only publicly accessible videos work. Private, friends-only or videos that require a Facebook login cannot be saved.
  • VidSave Pro provides MP4 files. The MP3 step is a separate conversion.
  • Do not re-upload, redistribute or use downloaded content commercially without the creator’s permission.

VidSave Pro does not store users' video links or personal data; requests are processed in real time. For Facebook’s rules and more legal context, see the Facebook Terms of Service and the U.S. Copyright Office.

  3. Paste the video link into the field on the homepage.
  4. Click Save Video.
  5. When the download options appear, choose HD or SD (quality depends on the original upload).

One-click while browsing: use the VidSave Pro Chrome extension

The Chrome extension adds a one-click save button to Facebook videos you see while browsing. Use it when you want faster saves on desktop.

  1. Install the extension from the Chrome Web Store: VidSave Pro Chrome extension.
  2. Open Chrome and browse to the public Facebook video on web.facebook.com or m.facebook.com.
  3. Click the VidSave Pro button shown on the video (the extension adds the save button).
  4. Choose HD or SD and download the MP4 file to your computer.

The extension is useful for frequent downloads while you browse.

Save on Android: use the VidSave Pro Android app

If you use Android, the VidSave Pro Android app makes saving quick from the phone. The app is free on Google Play.

  1. Install the app from Google Play: VidSave Pro Android app.
  2. Open the app, or share a public Facebook video link to the VidSave Pro app from the Facebook app or browser.
  3. Tap Save and choose HD or SD when prompted.
  4. The app saves an MP4 file to your device's Downloads folder.

The app is handy when you want to download video directly on Android before converting to MP3.

Convert MP4 to MP3: easy, private options for each device

After you have the MP4 file, use one of these private conversion options to get an MP3. If you prefer not to upload your file to an online service, use an offline app or desktop tool.

Desktop (Windows or macOS) — use a free offline tool

  1. Install a trusted media player or converter that can export audio (example option: VLC Media Player).
  2. Open VLC, then choose Media > Convert / Save (Windows) or File > Convert / Stream (macOS).
  3. Add the MP4 file you downloaded.
  4. Choose Convert and set the profile to MP3 (select audio codec MP3 and choose bitrate, e.g. 192 kbps).
  5. Pick an output filename ending in .mp3 and start the conversion. The MP3 will save to the chosen folder.

Android — use a trusted converter app or file manager

  1. Open Google Play and install a free audio converter app that works offline (search for "audio converter" and check reviews).
  2. Open the converter app and select the MP4 file from your Downloads folder.
  3. Choose MP3 as the output format and pick the bitrate or quality, then start conversion.
  4. The MP3 will appear in your Downloads or in the converter app's output folder; use your file manager to move or rename it.

iPhone (no iOS app from VidSave Pro) — convert safely

  1. If you saved the MP4 using Safari or Chrome on iPhone (see our guide to save Facebook video to iPhone camera roll), open Files and locate the MP4.
  2. Install a trusted audio converter app from the App Store that supports Files import, or use a reputable online converter if you accept uploading the file.
  3. Import the MP4 into the converter app and export as MP3. If using an online converter, remember uploading may expose the file to third parties.
Tip If privacy matters, prefer offline converters on desktop or Android. Online converters upload your file to a remote server — that's a privacy trade-off.

Quick tips on audio quality, file names and storage

  • Audio quality depends on the original video's audio and the MP4 quality you downloaded. Choosing HD doesn't improve audio beyond the source recording.
  • When converting, higher bitrates (e.g. 192–320 kbps) give better MP3 quality but larger files. Pick a bitrate that balances size and quality.
  • Rename files before you move them to music folders so they show correct titles in players.
  • Where files appear: on Windows/macOS, the browser download folder or the folder you chose during conversion; on Android, the Downloads folder or converter app folder; on iPhone, the Files app or Photos if you saved to Camera Roll.

Troubleshooting common problems

  • Save button is greyed out or download fails: the video may not be public or may require a Facebook login. Only public videos can be saved.
  • Slow downloads: try choosing SD instead of HD or check your network. Large HD files take longer.
  • Conversion errors: try a different converter app or re-download the MP4. Corrupt downloads can fail to convert.
  • Missing audio after conversion: the original video may have no audio track. Confirm audio plays in the MP4 before converting.
  • Browser not supported: VidSave Pro works in modern browsers on Android, Windows and macOS. On iPhone, open vidsavepro.com in Safari or Chrome and follow the site instructions.

Remember: VidSave Pro states it does not store users' video links or personal data and processes requests in real time.

Always respect creators and copyright. Downloaded content is for personal, offline viewing only unless you have permission to reuse it. Do not re-upload, sell, redistribute, or use downloaded audio commercially without the owner’s consent.
