Facebook recommends H.264 MP4 for the best video quality and fastest upload performance. Videos uploaded as AVI, WMV, or WebM are transcoded by Facebook's servers — a process that can degrade quality and delay your post going live. Encoding to H.264 MP4 before upload ensures your video publishes at the highest possible quality across Feed, Reels, and Watch.
Prepare a Facebook-ready H.264 MP4 at 1080p — fastest upload, best playback quality.
Facebook recommends MP4 with H.264 video and AAC audio. Facebook also accepts MOV, AVI, MKV, and WebM, but all are re-encoded on upload. Starting with H.264 MP4 produces the best quality output with the least processing overhead.
1080p (1920×1080) is Facebook's maximum resolution for standard video. Encode at 1080p for Feed and Watch. Reels support 1080×1920 vertical. Facebook does not support 4K public video delivery.
Facebook reduces bitrate during high-traffic periods and applies SD compression on older devices. For best results: upload an H.264 MP4 at 1080p, set bitrate to at least 8 Mbps, and avoid re-encoding an already-compressed file.
Facebook allows video uploads up to 10 GB per file for regular posts. Pages allow up to 10 GB; Ads depend on format but typically max out at 4 GB.
You can upload 4K source files to Facebook, but Facebook currently delivers video at a maximum of 1080p to viewers. Uploading a 4K source may improve the quality of the 1080p downscale, but the public-facing video will still be 1080p maximum.
