Frequently asked questions

Is this audio joiner free?

Yes. You can merge audio files for free, without signup, installed software, or a watermark on the joined file.

Which audio formats can I combine?

Upload MP3, WAV, M4A, AAC, OGG, or FLAC files. The combined upload must fit the 1 GB upload limit.

Will merging reduce audio quality?

When files are technically compatible and you keep the source format, Convertr uses stream-copy concat. Mixed formats, format changes, or crossfade use ffmpeg re-encoding.

Can I change the order before merging?

Yes. Add multiple clips, move them up or down, then join them in that exact order.
