How to use this tool
- Drop in two or more audio files.
- Reorder them with the up/down arrows if needed.
- Choose an output format and click Merge Audio.
Frequently asked questions
- Can I merge files in different formats?
- Yes — each file is decoded individually, so you can mix MP3, WAV, M4A, OGG, and other formats your browser supports as input, then export the combined result as any one output format.
- How do I control the order?
- Files are merged in the order they appear in the list — use the up/down arrows next to each file to reorder them before merging.
- Is there a gap or crossfade between files?
- No — files are joined directly end to end with no gap and no crossfade. Each file plays in full before the next one starts.
- Is my audio uploaded anywhere?
- No — every file is decoded and re-combined entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — merged in this tab | Yes, uploaded to process |
| Mix input formats freely | Yes | Varies — some tools require matching formats |
| Account required | Never | Often, past a certain usage level |
