How to save videos that I uploaded onto my facebook onto my iphone?

I can save pictures but I want to know how I can do that with videos.
I have uploaded videos onto my facebook from my computer, and now
I want to save them on my iphone.
If anyone knows, the help will be greatly appreciated!

You can't save them to your phone - you need to use a computer to do that - your phone can't do everything that computers can do

  • Why does the video quality look bad when uploaded to the computer? [iPhone 4]? When I upload my video to youtube in HD directly from the iphone, I go on the computer to watch it on youtube and the quality is perfectly normal. But when I copy the file from my iphone and onto my computer the video looks grainy? I wan't to put it into after effects and do some editing but how can I go about KEEPING the quality of the video? I don't get why it gets all grainy when I put it onto my computer vs. It being perfect when I upload it directly from my ipod to youtube?
  • When you charge your iphone on a different computer does anything get uploaded to it? I went to my friends house and decided to charge my iphone on his computer via USB cable. He doesn't have itunes installed on it, I just used it to charge my phone, and then took it off. Can any of my information be uploaded to his computer by doing this? Just curious, thank you.
  • Uploaded videos on youtube with music won't play on iphone? So I make ski edits and I use songs in them. I give credit to the artist in my edit and the description below, but for some reason they get copyrighted. I click acknowledge the copyright and usually they are fine but recently none of my recent uploads are working on mobile phones.
  • Why does picture and video quality diminish when uploaded to Facebook? I have an iPhone 7 Plus and the picture and video quality is really great. But when I post them to Facebook, the quality diminishes. The pictures and videos aren't nearly as clear as they are in my camera roll. Is there a reason why and is there a way I can fix that?
