Give Facebook's encoder the best possible source material so your videos look sharp in the News Feed — not washed out and blocky.
Compress for Facebook NowFacebook has one of the most aggressive video re-encoding pipelines on the internet. Every video you upload gets processed through Facebook's compression, and the output is often dramatically worse than what you uploaded. If you've ever wondered why your crisp, beautiful video looks like it was shot through a dirty window after posting to Facebook — that's Facebook's re-encoding at work. When you compress video for Facebook properly before uploading, you give Facebook's encoder a clean source that produces measurably better results.
Facebook is fairly permissive about what you can upload:
The generous 10GB limit might suggest you should upload the highest quality possible. But here's the counter-intuitive truth: uploading a 2GB file doesn't produce better results than uploading a well-compressed 50-100MB file. Facebook re-encodes to the same output quality either way. The only difference is that the 2GB file takes 20 times longer to upload.
Facebook creates multiple quality tiers from your upload. On mobile with slow connections, viewers see a very low-quality stream. On desktop with fast connections, they see a better version. But even Facebook's highest tier is aggressively compressed compared to what you uploaded.
The damage is worst on:
When you compress video for Facebook with the right settings, you minimize these problems by giving Facebook's encoder the cleanest possible input.
Upload at 1080p (1920x1080 for landscape, 1080x1350 for 4:5, 1080x1920 for vertical). Facebook downscales 4K uploads to 1080p for most viewers, and the downscale-then-re-encode process can actually produce worse results than uploading at the native 1080p resolution. Save yourself the upload time and start at 1080p.
6-10 Mbps for 1080p at 30fps. This is higher than what you'd target for TikTok or Instagram because Facebook's re-encoder is particularly aggressive and benefits from a higher-quality source. Don't go below 5 Mbps for 1080p content — you'll see artifacts that Facebook's encoder will amplify.
30fps for most content. Facebook supports 60fps, but the majority of content in the News Feed plays at 30fps. 60fps makes sense for gaming content, sports, and action footage where smooth motion matters. For talking heads, tutorials, and vlogs, 30fps saves data without visible impact.
H.264 with High profile. This is Facebook's most reliable input format. Facebook does process H.265 uploads, but H.264 produces the most consistent post-encoding results. Our video compressor uses H.264 by default.
128-192 kbps AAC stereo. Facebook's audio re-encoding is less destructive than its video encoding, so decent source audio translates well to the final post.
Facebook has been pushing Reels hard, and the format gets different treatment from standard Feed video:
For both formats, the same principle applies: compress video for Facebook with clean, properly encoded source material and Facebook's output will look its best.
Practical file sizes when you compress for Facebook:
These give Facebook quality source material while keeping upload times reasonable. Going bigger doesn't improve the end result — it just takes longer to upload.
Facebook has a "Upload HD" toggle in the mobile app settings (Settings → Media → Upload HD). Make sure this is turned on. When it's off, Facebook applies additional compression to your video before it even reaches their servers, meaning your carefully optimized file gets degraded before Facebook's standard re-encoding even begins. With HD upload on, your file reaches Facebook's encoders intact.
How Facebook compresses your video also depends on where it's posted:
Regardless of where you're posting, a well-compressed source file gives you the best possible result. Use our video compressor to prepare your file, then upload directly to Facebook with HD upload enabled.
For other platform compression guides, see Instagram, TikTok, LinkedIn, and Twitter/X.
In the Facebook app, go to Settings → Media → Upload HD and turn it on. Without this, Facebook pre-compresses your video before its standard re-encoding, degrading quality twice.
Facebook serves most viewers at 1080p or lower. Uploading 4K just increases upload time — it gets downscaled and re-encoded anyway. Native 1080p source often produces better results.
Vertical 4:5 (1080x1350) takes up more screen space in the mobile News Feed than 16:9 landscape. More screen real estate means more attention and engagement.
Facebook's re-encoder is aggressive, so starting with a higher bitrate source helps. Below 5 Mbps, you'll see source artifacts that Facebook's encoding amplifies.
