Frequently asked questions
Are my files uploaded?
No. Everything happens in your browser using your own device. Your audio never leaves your computer or phone.
Which formats can I save as?
MP3, WAV, M4A (AAC) or OGG (Opus). MP3 works everywhere; WAV is uncompressed and perfect for editing.
Can I join files with different formats?
Yes. Every file is converted to the same sample rate and channels automatically before joining.
How many files can I join?
As many as your device can handle. Long WAV outputs use more memory than MP3.
