Compress Video to 4GB
4GB is Telegram Premium's upload cap and Facebook's feed-video ceiling. At this generous target, compression is more about retaining every detail of a long recording than shrinking file size. A 3-hour 1080p recording compresses to 4GB with near-lossless quality; 4K footage up to 45 minutes can maintain full detail. This is the target for professional use cases — full conference recordings, wedding ceremonies, multi-hour streams — where the destination platform can handle large files and you want to minimize re-compression artifacts from the platform's own transcoder. Note: our uploader caps source files at 2GB, so this target is best when the source file is already under 2GB but the destination platform allows up to 4GB, letting you upload a higher-quality version than you'd need for tighter platforms.

Why compress video to 4 GB?
A 4 GB target matches Instagram Story, YouTube Shorts. Unlike a blunt percentage reduction, our tool calculates the bitrate math specifically for hitting 4 GB: total budget in kilobits, minus the audio track, divided by duration. That means a 30-second clip keeps more resolution than a 10-minute clip at the same target, which is how it should be.

How video compression to 4 GB works
When you compress a video to 4 GB, the tool analyzes your video's duration, resolution, and content complexity to calculate the optimal bitrate. The bitrate is the amount of data used per second of video. A lower bitrate means a smaller file, but also lower visual quality.
For a moderate target like 4 GB, the process involves: (1) analyzing your video's duration to calculate the maximum bitrate that fits, (2) scaling resolution down if the bitrate is too low for the original resolution (e.g., 1080p to 720p), and (3) encoding with optimized settings that prioritize visual clarity over mathematical perfection.
Default output is MP4 with H.264 video and AAC audio — the most universally compatible format, plays inline on every device, browser, and messaging app. Need MOV, MKV, or WebM? Switch in Advanced settings. For ~30-50% smaller files at the same visual quality on modern devices, pick the H.265 / HEVC codec.
Tips for best results at 4 GB
- Trim first: Shorter videos get more bitrate per second, which means better quality at the same file size
- Good lighting helps: Well-lit footage compresses more efficiently than dark or grainy video
- Avoid text overlays: Small text and fine details are the first things to degrade during compression
