M3U8 to MP4 Converter
Build a realistic MP4 conversion plan for authorized M3U8/HLS streams. The page checks manifest input, chooses copy or re-encode guidance, and generates an FFmpeg command without pretending to bypass access controls.
ffmpeg -i "playlist.m3u8" -c copy output.mp4
Copy when possible
Preserve quality when the audio and video codecs can live inside the target container.
Re-encode only when needed
Use H.264/AAC or another target when device compatibility matters more than speed.
Use owner-side tooling
Long playlists, private headers, and large jobs belong in a local or server-side workflow.
Four steps from playlist to MP4
Inspect the playlist
Check whether it is a master playlist, media playlist, live stream, or encrypted stream.
Choose the output path
Prefer codec-copy, then choose re-encode or audio-only only when the job requires it.
Generate a command
Create a readable FFmpeg command with optional owner-side headers.
Run responsibly
Use only authorized streams. This public tool does not bypass DRM, login, CORS, or signed URLs.
Converter questions
Does this page convert video in the browser?
R39 generates a real conversion plan and FFmpeg command. Heavy conversion is intentionally routed to owner-side tooling instead of pretending every browser can process long streams.
Will M3U8 to MP4 lose quality?
Codec-copy can preserve quality when codecs are compatible. Re-encoding can reduce quality and use more CPU.
Can it handle protected streams?
No. DRM, login-only content, signed URL expiry, key access, and CORS policy must be handled by the stream owner or authorized environment.
