How to Convert Facebook Videos to MP4 Online
Long-form Facebook uploads usually copy as facebook.com/watch/?v=… or short fb.watch/ links from Share. Public Page video posts may use facebook.com/PAGE/videos/… or /posts/ URLs. To convert a Facebook video to MP4, paste the same public watch or fb.watch link and save the preview stream. Paste whichever public URL Share gives you — we fetch the video on our servers and return whatever file Meta serves to logged-out viewers.
Supported link formats
https://www.facebook.com/watch/?v=VIDEO_IDhttps://fb.watch/SHORTCODE/https://www.facebook.com/PAGE/posts/POST_ID
Reels use facebook.com/reel/… — try the Facebook Reels Downloader for those URLs. Group, Marketplace, and private timeline links will not resolve.
Only public content you can open without joining a group works. Save files only when you own the content or have permission from the rights holder.
Common questions
How do I download a Facebook video?
Copy Share → Copy link on a public Watch video, paste the fb.watch or facebook.com/watch/?v= URL above, click Download, preview the MP4, then save through your browser. Works on iPhone, Android, and desktop when the video is public.
What video resolutions are available for Facebook Watch videos?
Facebook Watch serves up to 1080p full HD and 720p SD depending on the original broadcast or Page upload bitrate. SMDownloader delivers the highest resolution stream exposed by Meta.
Do fb.watch links work?
Yes. Paste the short link exactly as copied from Share — SMDownloader expands fb.watch URLs and returns the underlying public video when Meta serves it to logged-out viewers.
Can I download videos from private Facebook groups?
No. Group-only, friends-only, and login-walled uploads are out of scope — the post must be public content you can open without signing in.
Watch links vs reel links?
Long videos use watch/?v= or fb.watch. Reels use facebook.com/reel/…. Use the Facebook Reels Downloader for reel URLs and this page for watch and Page video links.
Why did my Facebook video link fail?
Private posts, deleted videos, and group-only uploads do not resolve. fb.watch and facebook.com/watch/?v= links copied from Share are the most reliable — copy again from Share or the address bar if preview fails.
Do fb.watch mobile shortlinks work on all devices?
Yes. Whether you copied the shortcode from an iPhone, Android, or tablet, our server-side resolver expands the link and serves a cross-platform MP4 file.
How do I convert a Facebook video to MP4?
Paste a public facebook.com/watch/?v= or fb.watch link above and click Download. SMDownloader resolves the progressive MP4 Meta exposes for logged-out viewers — typically up to 1080p — so converting a Facebook video to MP4 means saving that stream after preview, without installing a desktop converter or logging into Facebook.
