Compress a video for Facebook to upload faster and keep quality. Free, no upload, no signup. omnikitbolt re-encodes your MP4 right in your browser, nothing uploaded.
Big videos upload slowly to Facebook and get re-compressed anyway. Compress to a clean 1080p MP4 first so it uploads fast and holds its quality.

Facebook prefers MP4 with the H.264 codec at 1080p. omnikitbolt outputs exactly that, so your posts and reels upload cleanly and avoid extra re-compression.
Drop your clip, keep the 1080p downscale on for 4K footage, and pick a balanced quality preset. omnikitbolt re-encodes it locally and shows a before and after compare.
No. Everything runs in your browser with WebCodecs. Your video never leaves your device.
Smaller files upload faster, and a clean 1080p MP4 reduces how much Facebook's own compression degrades the final result.
