Compress Video for Facebook
Compress video for Facebook to hit the platform's 1080p H.264 spec and skip the re-encoding penalty. No upload, no watermark, runs in your browser.
Official platform specifications
Default compression settings target these specs to avoid the platform re-encoding your upload.
Notes & gotchas
- •Bitrate: target ~4 Mbps for 1080p (matches Facebook's streaming ceiling).
- •Audio: AAC, 128 kbps stereo, 48 kHz.
- •Frame rate: 24-30 fps recommended; 60 fps supported for gaming content.
- •Avoid H.265/HEVC — Facebook re-encodes with quality loss.
- •Frame rate: avoid VFR (variable frame rate) — causes audio drift.
- •Cover image: Facebook auto-selects from first frames; choose strong opening visual.
- •Captions: burn in critical text or upload .srt separately for accessibility.
Recommended FFmpeg settings
Want to compress video for Facebook before posting? The platform (Meta's flagship with 3+ billion monthly active users) recommends H.264 MP4 at 1080p with AAC audio for Feed, Reels, Stories, and Marketplace. Facebook's encoding ladder re-encodes every upload to multiple resolutions (240p through 1080p) for adaptive streaming, and any upload outside the recommended spec gets a heavier re-encoding pass that compounds artifacts. The classic symptom: you upload a crisp 4K clip and viewers see a soft, blocky 1080p version. Pre-compressing locally to Facebook's preferred spec (H.264 CRF 26 at ~4 Mbps) means the re-encoder applies minimal additional compression, preserving the quality you exported. This is especially important for Reels and Facebook Ads where algorithmic distribution favors higher-quality sources.
- 1Avoids Facebook's heavier compression pass on non-spec uploads — preventing compound quality loss.
- 21080p is the optimal balance of quality and load speed on Facebook's player. 4K uploads waste bandwidth (Facebook streams at most ~1080p); 720p looks soft on modern displays.
- 3Runs locally — saves bandwidth vs. uploading 500 MB raw files over mobile data. Pre-compressed 50 MB files upload in 1/10 the time.
- 4Works for Feed posts, Reels, Stories, Marketplace listings, and Facebook Ads — same compression rules apply across all placements.
- 5Facebook's algorithm indirectly favors higher-quality uploads through watch-time signals. This Facebook video compressor ensures viewers don't abandon grainy, artifact-heavy content, which would suppress distribution.
- 6Facebook Ads specifically has stricter quality floors than organic posts. Pre-compression ensures ad creative passes review without re-encoding cycles that delay campaign launch.

Cross-Platform Repurposers
Compress once for Facebook and the same file works for Instagram (both owned by Meta, same video specs). Cross-post without re-compression.
Frequently asked questions
Generous limits: Feed up to 10 GB, Reels up to 650 MB, Stories up to 4 GB total (typically 10-15 seconds per snap). The real issue isn't the cap — it's Facebook's re-encoding pipeline. Uploading a 4K 500 MB file is allowed but the platform will heavily re-encode it to ~4 Mbps with visible quality loss. Pre-compressing locally to ~50-100 MB at 1080p avoids the re-encoding penalty.
