We Measured 1,225 Facebook Video Downloads. 73% Failed — And It Is Not a Bug

Every downloader site says the same thing when a Facebook link fails: make sure the video is public. It reads like a brush-off.

We had the data to check whether it was true, so we did.

The numbers #

These are real user jobs from our own servers over 30 days — not a benchmark we designed, just whatever people actually pasted in.

Same code path, same servers, same month. A 122x difference between TikTok and Facebook is not something you explain with bugs.

The smoking gun: it depends on where you got the link #

Splitting the Facebook jobs by the shape of the URL is where it gets interesting:

Look at the two extremes. A /share/v/ link fails 92% of the time. A /reel/ link fails 36%. Both point at Facebook videos. Both go through identical code.

The difference is where the human got the link.

When you tap Share → Copy link inside the Facebook app, you are copying something out of a feed that Facebook assembled for you, while you were logged in. That feed is full of posts from friends, closed groups and restricted audiences. You can see them. A server visiting as an anonymous stranger cannot.

When someone pastes a /reel/ URL, they usually found it while browsing public content — so it is far more likely to actually be public.

/share/p/ at 100% makes sense once you see it: p is for post, and most of those are photos, text or link posts. There was never a video to download.

We checked whether it was our own fault first #

The honest failure mode here would be blaming Facebook for our own broken code, so we tested that directly.

We took 8 Facebook URLs that had previously downloaded successfully on our system and ran them again:

The extractor still handles public Facebook video. It fails only on the links that were already failing — which is what you would expect if the difference were the content, not the code.

We also ruled out the usual suspects: routing through a residential proxy changed nothing (we A/B tested a second, proxy-free instance against the same URLs and got byte-identical results), and the extractor is on its current release.

Then we took 15 failing /share/v/ links and followed each redirect to see what they actually pointed at:

So it is not only closed groups. Plenty of apparently-normal Reels fail too — because "posted by a person" and "visible to the public" are different things on Facebook, and most people never change the default.

The part that genuinely is tooling #

We are not going to pretend all of it is Facebook.

The widely-used open-source extractor that handles most platforms currently cannot parse Facebook pages at all — it returns Cannot parse data on every reel we tested, with or without cookies. That is a real, upstream, unfixed problem, and it is why so many downloader sites got worse at Facebook at the same time.

But that explains why tools fail. It does not explain the 122x gap with TikTok, because the same broken-extractor situation would apply there too. Two separate things are happening at once, and the bigger one is privacy.

What this means if you are trying to download a Facebook video #

What we changed after seeing this #

Two things, both about being honest with people rather than pretending we can fix Facebook.

The first is speed of failure. A doomed Facebook job was burning 82 seconds on our servers, because the system retried three times before giving up — sensible for a flaky network, pointless when the answer is a definite "this is not public". Across 898 failed jobs that is roughly 20 hours of people watching a spinner to be told no.

The second is the message. "Something went wrong" is useless when the real answer is "this video was never public". Telling someone that immediately is worth more than another retry.

The uncomfortable conclusion #

A 73% failure rate looks like a broken product. We published it anyway, because the alternative is the thing every downloader site does — quietly fail, blame the user, and let them try six more tools that will fail identically.

Facebook is not YouTube. It was built as a private network between people who already know each other, and it still mostly behaves like one. TikTok downloads at 99.4% because TikTok is for strangers. Facebook downloads at 27% because Facebook, mostly, is not.

That is not a bug in anyone's software. It is what the platform is.
