QUICK ANSWER
Is it possible to convert ROFL to MP3?
No - not a direct conversion.

To capture audio from a League replay, play it in the League client, record desktop audio with OBS Studio, then extract the audio track from the recording. The ROFL file itself holds only game-state data - no audio stream exists inside it.

Why convert ROFL to MP3?

A ROFL file (League of Legends Replay) stores player inputs, unit positions, game events, and a JSON statistics block - no audio stream of any kind. All champion sounds, music, and announcements heard during playback are synthesized in real time by the game engine. MP3 (MPEG-1 Audio Layer III, standardized 1993) requires actual audio data as input. Because no audio exists inside ROFL files, no converter can produce .mp3 output.

How to convert ROFL to MP3

OBS Studio FREE

Play the .rofl file in the League client and use OBS Studio to record desktop audio; then extract the audio track from the resulting recording file using ffmpeg.

Quality & what to watch

  • ROFL files are typically only a few megabytes for a 30-minute game, confirming no audio is stored inside them.
  • ROFL replays are tied to the patch they were recorded on; after a League update, old files will not open.
  • Audio quality depends on your OBS recording settings and system audio output, not on anything in the ROFL file.

Frequently asked questions

Why does a ROFL file have no audio?
The format stores game-state data - inputs, positions, events - not media; the game engine generates all sounds in real time during playback.
Can any tool extract audio from a ROFL file?
No - any program claiming to convert ROFL to MP3 is either misleading or will produce an error, because no audio exists inside the file.
My ROFL file will not open. Can I still access its data?
The JSON metadata block (champion picks, KDA, patch version) can be read by some third-party tools even after the replay expires, but it contains statistics only, not audio.
