Audio Joiner — Frequently Asked Questions
Everything you need to know about using Audio Joiner.
Which audio formats can I join?
MP3, WAV, OGG, M4A, and FLAC. You can mix formats — output is a single file in your chosen format.
Will my audio quality drop after joining?
If all input files are the same format, files are concatenated directly with no quality loss. Different formats are re-encoded once, which is minimal but not lossless.
Can I rearrange the order of files?
Yes. Drag clips up or down before joining. The output plays them in the order shown.
Is there a file size or count limit?
No hard limit. The practical cap is your device RAM — typically 1–2 GB total audio works on desktop, less on mobile.
Do you upload my audio files?
No. Joining happens entirely in your browser using the Web Audio API. Files never leave your device.
