Facebook compresses videos in the feed, but the HD source is still there. xi (apiproai.com) lets you pick the highest available quality — up to full HD 1080p — when downloading any public Facebook video.
There are many ways to save Facebook videos in HD — screen recording, browser extensions, third-party apps — but most come with trade-offs. Screen recordings lose quality and capture notifications and UI elements. Third-party apps often demand your Facebook login (a real account-theft risk), show aggressive ads, or quietly upload your contacts. Browser extensions can read everything you browse.
xi avoids all of that:
On iPhone (Safari): open xi at apiproai.com, paste the link and tap Download. When the file is ready, tap the download icon in Safari's address bar, open the file, then tap the Share button and choose Save Video (or Save Image) to move it into your Photos library.
On Android (Chrome): the process is even simpler — after tapping Download on xi, the file saves straight to your Downloads folder and appears in your gallery app automatically.
On desktop: paste the link into xi, click Download, and the file lands in your browser's download folder. From there you can rename it, move it, or import it into any video editor.
"No media found" or empty result: the most common cause is a private or deleted post. Copy a fresh link directly from the Facebook app (Share → Copy Link) rather than from a screenshot or a third-party site, and try again.
Download starts but never finishes: switch to a stable Wi-Fi connection and avoid VPNs that throttle traffic. Very long videos can take a minute or two to prepare — give it time before retrying.
Button doesn't respond on iPhone: make sure you're using Safari (not the in-app browser of another app). If the page seems stuck, pull down to refresh and paste the link again.
File won't play: MP4 and MP3 from xi play in every modern player. If your gallery app can't open it, try VLC — it's free and handles everything.
Up to 1080p HD for videos uploaded in HD. Some older uploads max out at 720p or SD.
The uploader's original was low quality, or Facebook only stored an SD copy.
Usually yes — higher-quality renditions typically carry better audio streams too.
HD can be 3-5x larger than SD for the same video.
