Free, step-by-step guide. No signup needed — everything runs in your browser.
1

Navigate to the tool. No signup required, nothing to install.
2
Upload your audio files
Drop your MP3, WAV, OGG, or M4A files. Add them in the order you want them joined.

Tips for best results
- Use files with the same sample rate (44.1 or 48 kHz) and bit depth for the cleanest join.
- WAV input → WAV output preserves quality with no re-encoding. MP3 inputs get re-encoded once.
- Mono and stereo files can be mixed — output is stereo by default.
- No fixed file count limit, but very long files (1 GB+) may stall on lower-end mobile.
- For a smooth transition between clips, trim silence from the end of each file first using Audio Trimmer.
