How to Download Facebook Videos Using FDown.vn
Step 1: Copy the Facebook Video Link
Open Facebook on your browser or mobile app. Find the video you want to save, tap the Share button, then select Copy Link to grab the video URL.

Step 2: Paste the Link into FDown.vn
Open your browser and go to FDown.vn. Paste the copied video link into the input box on the homepage, then click the Download button to let the system process your request.

Step 3: Select Your Format and Save the Video
Once the system finishes processing, you will see the available download options:
Select MP4 if you want to save the video, or MP3 if you only need the audio.
Pick your preferred quality: SD, 720p, 1080p, HD, or 4K.
For HD quality and above, Facebook stores video and audio as separate files. Simply click Render & Download and wait a few seconds while FDown.vn automatically merges them into a single complete file.
When the file is ready, click Download now to save the video or audio track to your device.

Things to Keep in Mind:
- For videos at HD quality or higher, Facebook separates the video stream and audio stream into two files. FDown.vn handles the merging process automatically before delivering your final download.
- If you need to download a private Facebook video or a video from a closed group, use the Private Facebook Video Download feature on FDown.vn and follow the step-by-step instructions provided on that page.
