Does this download every public Facebook video?
No. Public visibility on Facebook is not the same as an authorized download API. Meta’s Graph API returns a source field only when the access token is allowed to read that video, typically for videos you own or Pages you admin.
Why was my URL rejected?
The link may not be HTTPS, may not be on facebook.com or fb.watch, or may be a post/share URL without a video id. Open the video itself and copy that address.
Do you keep the links I paste?
No. Submitted video URLs are not written to the WordPress database. Rate limiting uses a short-lived technical key and is not a browsing history.
Is HD or 4K guaranteed?
No. Only formats Meta actually returns are listed. If none are returned, the site will not invent quality options.
Can I use this for other people’s videos?
Only if you already have lawful access through Meta (for example, you admin the Page). Do not use this site to take videos you do not have rights to keep.
