Facebook already stores its videos as MP4, so saving one as an MP4 is not really a conversion. The downloader finds the MP4 files Facebook published for a link and hands you the one you choose. Paste an FB video link in the box above, pick a quality, and the file downloads straight to your phone or computer, online and with nothing to install.
What you get: a standard MP4 file
The file is an MP4 container holding H.264 video and AAC audio, the most widely supported pairing there is. Every file offered here has its sound built in. Facebook also streams picture and sound separately, and those halves are left out, so there is nothing to join afterwards.
It plays in the Photos app on an iPhone, the gallery on Android, the built-in player on Windows, QuickTime on a Mac, VLC and every current browser.
Why nothing is re-encoded
Converting a video means decoding it and compressing it again, and every round of compression throws detail away. Because Facebook’s file is already an MP4, re-encoding it would make the download slower and the picture slightly worse, for nothing. You receive the same file Facebook’s own player streams, which is also why no watermark is added and no logo appears in a corner.
Choosing a quality before you download
Most videos come in two or three versions: 1080p or 720p in HD, and a smaller SD file. The list shows the size of each one before you commit. HD is the right choice for a large screen or for editing; SD saves data and storage when the video only needs to look good on a phone.
If the best on offer is SD, the upload itself was small. The HD page explains why that happens and what the file sizes look like.
MP4 or MP3?
An MP4 keeps the picture and the sound. If you only want the audio of an interview, a song or a lecture, choose Convert to MP3 instead: the file is a fraction of the size and plays in any music app, offline. Facebook to MP3 covers the audio quality to expect.
Using the MP4 in a video editor
Because it is plain H.264 and AAC, the file imports straight into CapCut, iMovie, Premiere Pro, DaVinci Resolve and Final Cut, with no conversion step. It keeps the shape it was posted in: Reels are vertical 9:16, most feed videos are 16:9 or square, and the frame rate is the one the uploader recorded.
Saving the MP4 on Android or a computer
On Android, Chrome and most other browsers save the MP4 to the Downloads folder, and the gallery picks it up shortly after. On Windows, macOS and Linux the file lands in your browser’s download folder, usually Downloads. Nothing needs installing on either, and the same page works on a tablet.
Why the file name is a number
Facebook names the file, and the name is usually a long run of digits rather than the video’s title. If you are saving several videos, rename each one as soon as it lands: a name you chose is the only way to tell them apart in a folder later.
When the MP4 will not play
A download that stopped early leaves a file that will not open, so download it again on a steady connection. On an iPhone, a video saved from Safari waits in the Files app until you move it to Photos with Save Video. And if an old media player shows the picture but no sound, or the other way round, try VLC or a browser: every file here carries both.
