Step by step
Why the file size is worth reading first
Facebook publishes more than one rendition of a video, and the largest is frequently many times the size of the one you were watching. The size column is measured from the source rather than estimated, so choosing between a light file for sharing and a heavy one for archiving is an informed decision.
Nothing downloads until you press a download button. Fetching a link only reads what is available.
About audio in the file you get
Every file offered is one complete file that already contains both the picture and the sound; the audio column reads included for all of them.
Where Facebook also publishes a higher resolution, it sometimes does so only as separate picture and sound streams. Saving that as a single file is not something this tool does, and it says so rather than quietly giving you a silent video.
What cannot be saved
Videos that Facebook only shows to signed-in users, videos in closed groups, and anything behind a login. The tool does not sign in and cannot use your account.
Profile links, group links and photo pages are also refused with an explanation — there is no single video behind those addresses to save.
Frequently asked questions
Where does the file go?
Into your browser's download folder, normally called Downloads.
Can I choose the resolution?
You can choose among the files the source publishes. If a higher resolution exists only as separate picture and sound streams, it is reported as not downloadable as one file rather than silently omitted.
Do I get a silent video if only HD streams exist?
No. The page tells you that case explicitly instead of offering a video without sound.
