Frequently asked questions
Can I join MP3 files without losing quality?
The files are joined and saved again as one MP3 at high quality (192 kbps or more), which sounds the same as the originals. Choose WAV if you need a lossless result.
Can I join files of different formats?
Yes. You can mix MP3, WAV, M4A, OGG, FLAC and even the sound from MP4 videos. Everything is converted to the format you choose.
What does “Even out the volume” do?
It makes every file about equally loud, so a quiet recording doesn't get lost next to a loud one. It's useful for joining voice notes, lessons or songs from different sources.
Are my files uploaded?
No. Your audio is joined in your browser and never leaves your device.
