Repair garbled MIDI lyrics, track names and markers, or embed timestamped LRC lyrics in your browser. Choose an encoding, check the text and download the MIDI. Files stay on your device; existing notes, timing and controller events are preserved.
Input
Existing .mid/.midi files with text meta events that need encoding cleanup
MIDI formats
Output
Browser-local MIDI output in the selected encoding; notes, timing, tempo, velocity, and controllers are kept unchanged
Use case
Garbled MIDI lyrics, track names, instrument names, markers, cue points, and copyright text cleanup
Choose a model for your material and purpose, and review the examples before submitting.
Cost, time, formats and parameters depend on the selected model.
MIDI Converter follows mason369/midi-encoding-converter: it rewrites existing MIDI text meta-event encodings to the selected target encoding in the browser, with UTF-8 as the recommended default, without upload or model inference.
The MIDI converter is the mason369/midi-encoding-converter path for browser-local MIDI text meta-event recoding.
Parses LRC and Standard MIDI File bytes directly and writes FF 05 lyric events without a neural model.
Official repository - current
The converter repository documents the binary MIDI parsing path: parse MThd/MTrk chunks, find text meta events 0x01-0x07, decode source text bytes, re-encode to the target text encoding, recalculate track lengths, and write MIDI output. No neural paper or model ranking applies.
MIDI Manufacturers Association - current
The MIDI Manufacturers Association specification defining how lyric meta events are stored inside a Standard MIDI File, which is the exact structure this tool writes when embedding timestamped LRC lyrics.
No paper links are provided.

Supported formats: mid, midi - Max 10 MB
Used when auto-detect is off. Applies only to MIDI text meta events, not notes or timing.
Browser-local mode writes the selected target encoding: UTF-8, Shift_JIS, GBK, Big5, EUC-KR, or ISO-8859-1. UTF-8 remains the recommended default for modern DAWs and MIDI editors.
