Use page source for a Facebook video you can already view in your own account.
Private Facebook Video Downloader Features
✓
Facebook video URL input: The first field accepts a Facebook video or post URL and prepares the address used for the page-source step.
✓
Generated page-source address: Use the Copy control to open the prepared view-source address in the browser session that can play the video.
✓
Formats found in the submitted source: FastVid shows only the video or audio options identified in the page source you submit.
✓
Desktop browser workflow: A desktop browser is recommended because some mobile browsers do not open view-source pages.
Frequently Asked Questions
When should I use the page-source downloader instead of the main link field?
Use it when an authorized Facebook video already plays in your account but the public link field cannot access it. This workflow prepares a source address, examines the source you submit, and returns an option only when it finds a usable video reference.
Does page source bypass a friends-only or private-group restriction?
No. You must already be able to open and play the video in the signed-in Facebook session you are using. Source extraction does not grant access to another account, group, or audience.
What is FastVid looking for inside the copied HTML?
The submitted page source can contain media references that are unavailable to an unsigned public-link request. FastVid looks for usable video references and lists only the files it can identify there.
Is the Facebook source processed only inside my browser?
No. The video URL and source text leave your device and are sent to FastVid for the extraction request. Inspect what you copied and remove unrelated private information before submitting it.
What should I remove from the source before I submit it?
Remove unrelated personal or sensitive data you do not want processed. Never paste a Facebook password, session cookie, access token, or authentication header; the form expects the video URL and the page source you deliberately reviewed.
Why does the view-source address turn into a search query?
The browser may not support view-source: addresses, which is common on mobile. Copy the prepared address into the same signed-in desktop browser that can play the video rather than entering it in a search box.
I pasted a full source document. Why did extraction still find nothing?
Confirm that the source came from the exact video page in the browser session where it plays, not from a feed or different tab. A complete document can still lack a usable media reference, in which case FastVid cannot create a result.
Why is source text over 5 MB rejected?
The extraction form enforces a 5 MB request limit. Reopen the exact video page and copy its source once more; if that complete source still exceeds the limit, this workflow cannot accept the page.
Why can't the private workflow promise MP4, HD, or audio?
Its result is limited to the media references present in the source you submitted. File type, resolution, and audio can differ from one video to another, and missing versions cannot be generated from the HTML.
