How it works
How to use the Audio Merger tool
- 1
Add audio files
Two or more files, in any supported format.
- 2
Set the order
Drag files into order and choose a gap between them.
- 3
Merge
Download one combined MP3.
Mix formats freely
Files with different formats, sample rates and channel counts are normalised to 44.1 kHz stereo before joining, so a WAV voice memo and an MP3 song merge seamlessly.
Limitations
We’d rather be upfront about what this tool can’t do yet:
- Output is MP3 at 192 kbps.
- Total input up to 300 MB per file.
FAQ
Frequently asked questions
Are my files uploaded?
No. Everything runs inside your browser on your own device, so your files are never sent to FreeToolsDaily or anyone else.
Why does the first conversion take longer?
The first time, your browser downloads the FFmpeg engine (about 30 MB). It’s cached afterwards, so later conversions start almost instantly.
Can I add a pause between tracks?
Yes — choose 1 or 2 seconds of silence.
