How many MP3 files can I merge at once?

There is no hard limit on the number of files you can merge. Each individual file can be up to 30 MB.

Will the quality of my MP3s be affected?

The merged file is re-encoded at 192kbps so all tracks come together consistently, even if your original files had different bitrates. This means a small amount of quality change compared to the originals.

Does the order I upload files in matter?

Yes. Files are combined in the exact order shown in the file list. Use the arrow buttons to rearrange them before merging.

What happens if one of my files is corrupted?

The whole request fails with a clear error rather than silently producing a merged file that's missing a track — every file is checked individually before merging starts.

How it works

1
Upload your MP3 files
Drag and drop your MP3 files into the upload area, or click to browse. You can add up to 30 MB per file.
2
Arrange the order
Use the arrow buttons to move files up or down until your desired order is set. Remove any file you no longer need.
3
Merge
Click Merge Audio. All files are combined on our servers in the order you specified.
4
Download the merged MP3
Your merged track is ready to download as a single file named merged.mp3.

Features

Reorder before merging
Use the move up/down buttons to arrange your files in exactly the right order before merging.
Merge any number of files
Combine two or more MP3 files in a single operation — no limit on file count.
Consistent output quality
Re-encoded at 192kbps regardless of each input's original bitrate, for a consistent result.
Catches bad files before merging
Each file is validated individually first — ffmpeg's concat step would otherwise silently drop a corrupted file from the output instead of erroring.
