Use the matching tool to start straight away. The download begins in your browser and shows its size and progress on the page.
Most Facebook videos exist in two renditions: a standard-definition file that loads quickly on weak connections and a high-definition one. The downloader lists whichever exist for that specific video, so a clip uploaded from an old phone may only have SD. Because Facebook recompresses uploads, the HD file is a good match for what you saw on screen but not a studio master.
Links on facebook.com/watch, links ending in /videos/ followed by a number, Reels links containing /reel/, and short fb.watch links all work. If you copy a link from a news feed post it often points to the post rather than the video, so open the video itself first and copy the address from there for the best result.
Only videos set to Public can be downloaded. Anything inside a private group, shared with friends only, or from a profile with restricted audience needs a login and will return an error. The downloader never asks for your Facebook credentials, so do not enter them on any site claiming to bypass this.
Public Reels are saved the same way as any other video. Live broadcasts become available after the stream ends and Facebook has processed the recording. While the broadcast is still live, the link will not return a file yet.
Interviews, sermons, webinars and music clips often work well as audio. The Facebook to MP3 tool extracts the sound as a 192 kbps MP3, which is much smaller than the video and easier to play in a car or on a music player.
Public does not mean free to reuse. Many Facebook videos are owned by publishers, broadcasters or individuals who retain full copyright. Save videos for personal viewing, for your own uploads, or when the owner has said you may. Do not re-share protected material as your own.
