FFmpeg Command Line
The most versatile and powerful option, suitable for long videos and all kinds of complex cases:
# Remux directly (no re-encoding, fast)
ffmpeg -i "https://example.com/index.m3u8" -c copy output.mp4
# Re-encode to H.264 + AAC (best compatibility)
ffmpeg -i "https://example.com/index.m3u8" -c:v libx264 -c:a aac output.mp4For AES-128 encrypted streams, FFmpeg detects and decrypts them automatically (provided the key is accessible).
Browser-Based Conversion
Our online tool is built on FFmpeg.wasm, running FFmpeg inside your browser. No data is ever uploaded, making it ideal for privacy-sensitive scenarios.
