How to Download on iPhone & Android Mobile Devices

To save files directly to your phone, use your system's default mobile browser:

Android Devices: Open Facebook and tap share to copy the video link. Load our site in Chrome, paste the link, and choose your format. The video will save directly in your phone's default Downloads folder.
iOS Devices (iPhone/iPad): Copy the video link from Facebook, then open Safari to visit our site. Safari's native download manager allows you to save the file directly to your Files app, avoiding standard playback window redirections.

No. We prioritize your privacy. All processing runs through temporary local file buffers that are instantly wiped out once your download completes. We do not store or track any URLs or video history.

Because 4K upscaling re-encodes the YUV video frames in real-time on our server using FFmpeg. To keep the process safe and avoid resource crashes, we restrict the encoding to exactly 1 CPU core thread, meaning the browser downloads the stream at encoding speed.

Device Compatibility Guide & Browser Extension Setup

FB4KDownloader.com is designed to work across all major platforms, but different operating systems handle media downloads in their own way. Here is a quick reference to make sure you get the best experience:

1. Windows & MacOS Desktop

Downloads on desktop are the most straightforward. Tapping the HD or SD download buttons will directly trigger your browser's default download manager. For Chrome users, we also offer a lightweight **Chrome Extension** that adds instant download buttons directly underneath videos while you browse Facebook.

2. Apple iOS (iPhone & iPad)

iOS has strict sandboxing rules. If you tap download in Safari, the video may play inside the Safari media player instead of saving. To bypass this, **long-press the download button** and select **"Download Linked File"**. The video will download in the background and can be accessed inside the iOS "Files" app.

3. Google Android

Android Chrome handles downloads seamlessly. Tapping any download button will save the file directly to your local downloads folder, and you will see a progress bar in your notification drawer.
