Free online GP4 to OGG converter

Some players, websites, and devices cannot open Guitar Pro tablature but can play OGG audio. Converting the score lets you share or practice it as a rendered sound file, although the result is synthesized audio rather than a recording.

What the GP4 format is

.gp4 is the Guitar Pro 4 binary score format from Arobas Music. It stores guitar tablature, standard notation, tempo, lyrics, repetitions, effects, track settings, and instrument assignments; it does not contain recorded audio. Guitar Pro 4, newer Guitar Pro releases, and some compatible notation programs can open GP4 files. The format is common in exchanged guitar tabs and older composition archives.

What the OGG format is

OGG is a multimedia container, most commonly carrying audio encoded with the lossy Vorbis codec. Ogg files can also contain codecs such as Opus, but a normal GP4 conversion generally produces Ogg Vorbis. Vorbis gives smaller files than uncompressed WAV at comparable listening quality and suits practice tracks, web playback, and sharing when the target software supports OGG.

How to convert GP4 to OGG

Using 101convert.com: upload the .gp4 file, select OGG as the output format, start the conversion, and download the resulting file. The service must parse the tablature and render its tracks; it cannot recover a studio recording because GP4 contains notation and playback instructions only. If the file is private or the conversion does not reproduce the score correctly, use the local workflow below.

Using Guitar Pro, MuseScore, and FFmpeg:

1. Open the file in Guitar Pro 4 or a compatible current Guitar Pro version. Verify tempo, repeats, muted and soloed tracks, instrument assignments, and the sections you want rendered.
2. Choose File → Export → MIDI and save the result as song.mid. MIDI stores the score’s performance events, not the final audio.
3. Open song.mid in a MIDI-capable renderer such as MuseScore or TiMidity++. In MuseScore, assign suitable instruments or soundfonts, then choose File → Export and export a WAV file such as song.wav. MuseScore can also export OGG in versions that provide that option.
4. For a consistent command-line conversion, encode the WAV with FFmpeg:

ffmpeg -i song.wav -c:a libvorbis -q:a 5 song.ogg

The Vorbis quality scale uses larger values for higher quality and larger files; -q:a 5 is a practical general-purpose setting. Use -q:a 7 or higher for less compression, or replace it with a fixed bitrate such as -b:a 128k when a receiving system requires one. Keep the WAV until the OGG has been checked.

Quality and compatibility limits

The synthesizer and soundfont determine the audible result. MIDI export does not preserve Guitar Pro’s original playback engine, samples, amplifier tone, or every notation-specific articulation. Bends, slides, harmonics, effects, drum mappings, dynamics, and repeats can sound different or be omitted, so inspect the rendered audio before sharing it.

OGG Vorbis is supported by many desktop players, browsers, and Linux applications, but some phones, car stereos, editing programs, and hardware players require MP3 or WAV. If compatibility is more important than file size, export WAV or encode that WAV directly to the format required by the destination. Re-encoding OGG to another lossy format causes another generation of quality loss.
