Facebook Video Downloader (4K MP4)

Facebook and Instagram share the same Meta video infrastructure but differ in format: Facebook supports 16:9 widescreen, 1:1 square, and vertical 9:16 formats; Instagram leans vertical. A single Reel often appears on both platforms — downloading from Facebook generally yields the same file as downloading from Instagram.

Facebook hosts one of the largest libraries of long-form video on the consumer web: Watch uploads, Pages' marketing videos, Live replays, Reels, and videos embedded in ordinary posts. Because Facebook videos are often shared inside groups and closed communities, saving a public copy for offline reference is a common use case, especially for tutorials and cooking recipes that creators may later remove.

Facebook encodes videos in H.264 at multiple bitrates: SD (360p/480p), HD (720p/1080p), and selectively 4K for verified Pages with high-bitrate source uploads. Audio is AAC. Live replays are served as H.264 MP4 after the stream ends, typically at 720p.

For 4K downloads, confirm the source Page actually uploaded in 4K — most Pages re-encode their sources before upload, so "4K" labels can be misleading. Facebook URLs often contain tracking parameters (?fbclid=, ?mibextid=) that do not affect the video. Your downloader will strip them automatically. Live replays may be chaptered. A full download gives you one long file; if you need segments, trim afterward in any MP4 editor.

4K (also called 2160p or UHD) is 3840×2160 pixels — four times the pixel count of 1080p Full HD. A 5-minute 4K video typically weighs 300–600 MB, compared to 70–150 MB for the same clip in 1080p. You need the storage and the bandwidth to justify downloading at this tier: 30 minutes of 4K footage can easily exceed 2 GB.

4K downloads are only possible when the source was actually uploaded in 4K. Most consumer uploads to social platforms cap at 1080p; 4K is common on YouTube and some Facebook Pages, rare on Instagram, and essentially unavailable on TikTok and Twitter. If your download comes back at 1080p even though you asked for 4K, the source simply does not have a 4K tier.

For viewing on a 4K TV or studio monitor, the difference from 1080p is dramatic — textures, small text, and fine detail all become legible. For viewing on a phone or laptop at normal distance, the difference is usually below perception threshold.

• 4K downloads are 5–10× larger than 1080p. Plan storage accordingly. • Only download 4K when the source truly ships 4K — otherwise you are just saving an upscaled 1080p. • Casting 4K to an older TV may cause stuttering; check your device supports 4K playback first.

MP4 is the dominant container format for video on the web. It wraps the video and audio streams into a single file that plays on iOS, Android, Windows, macOS, Linux, Chromebooks, smart TVs, game consoles, and virtually any device made this decade. Most downloads from our tool produce MP4 because it maximizes compatibility.

MP4 is a container, not a codec. Inside the MP4 you might have H.264 video (most compatible), H.265/HEVC (more efficient, less universally supported), VP9, or AV1 (very efficient, newer devices only). For maximum compatibility, stick with H.264 MP4 — it plays everywhere.

• If an MP4 fails to play, check the codec inside — older devices may not support HEVC or AV1. • For editing, H.264 MP4 is the safest bet across timelines and editors.

This downloader accepts the following Facebook URL patterns:

• facebook.com/watch?v=VIDEO_ID • facebook.com/USERNAME/videos/VIDEO_ID • facebook.com/reel/VIDEO_ID • fb.watch/SHORT_CODE/ • m.facebook.com/... (mobile)

You can paste a URL copied from the Facebook app's Share menu or from a desktop browser's address bar — either will work, and tracking parameters are stripped automatically.

Community admins save important announcements before members move to new groups. Marketers archive successful ad creatives. Families save Live replays of weddings, graduations, and reunions. Small businesses preserve their own Page videos across platform migrations.

Private group videos: Videos posted inside closed or secret groups require group membership — they are not accessible via public scraping.

Shared videos vs. original: A "Share" of a video reuses the original's media URL. If the original is deleted, every share breaks.

Live replays: Active live broadcasts cannot be downloaded as a file. Wait for the broadcast to end and the replay to publish.

Cross-posted from Instagram: When a Reel is cross-posted from Instagram, some URL forms only work on the original platform. If a Facebook URL fails, try the matching Instagram URL.
