What formats does this audio merger support?
You can upload MP3, WAV, M4A, MP4, OGG, FLAC, AAC and most common audio formats. The server merges your files and returns a single track in the output format you choose (for example MP3 or WAV).
Is this MP3 joiner online free?
Yes. You can use the audio merger for free without creating an account. To keep performance stable for everyone, there may be fair daily limits per browser and IP.
Can I change the order after uploading?
Yes. The list shows all files that will be merged. You can use the up and down buttons on each row to move tracks until the order matches the final audio you want.
What does crossfade between tracks do?
When crossfade is enabled, the end of one file gently overlaps with the start of the next for a smoother transition. You can choose a short crossfade time in seconds or leave it disabled for hard cuts.
Are my audio files stored on your servers?
Files are processed only for the time needed to merge them and generate the result. The tool is designed for quick, everyday tasks and does not require registration.
