Why use this tool

🎯
Compress to exact size

Pick 10MB → output ≈10MB. Bitrate computed backwards from duration to hit target.

🎨
2-pass high quality

Pass 1 analyzes complexity, pass 2 allocates bitrate smartly. 30-50% better quality vs 1-pass.

🔒
No watermark

Unlike Veed/Kapwing free tier with watermark on compress, this tool outputs 100% clean.

Uses FFmpeg 2-pass with H.264 + AAC 128kbps audio. Pass 1 analyzes each scene's complexity. Pass 2 allocates higher bitrate to complex scenes, lower to simple — result: smaller file, still good quality.

Why 2-pass beats 1-pass? Example: interview + action footage. 1-pass uses same bitrate throughout → action scenes blur. 2-pass detects action needs more bits → action stays sharp, interview still fine.

FAQ

Why isn't output exactly 10MB?

Bitrate × duration is an estimate. ±10% variance due to container + audio overhead. Always stays under target for Facebook/Discord upload.

Does quality hold compressing 100MB → 5MB?

Depends on duration. 30s OK, 5min clearly blurry. Tool warns when target is too low for duration.

Does it strip audio?

No. Audio re-encoded AAC 128kbps, fine for music/voice.
