Merge Audio — Frequently Asked Questions
How many audio files can I merge at once?
There is no hard limit. You can merge as many files as you need. However, merging many large files may be slower depending on your device's memory and processing power.
Can I merge files in different audio formats?
Yes! You can mix different formats — for example, an MP3 and a WAV file. All files are automatically converted and concatenated into a single MP3 output.
Can I change the order of the audio files?
Files are merged in the order they appear in the file list. Add them in the order you want them to play in the final output.
Is there a gap between the merged audio files?
No. The audio files are concatenated seamlessly with no gaps or silence between them. The transition is instant and smooth.
What is the output format?
The merged audio is exported as an MP3 file for maximum compatibility across all devices, platforms, and media players.
Is my audio uploaded to a server?
No. All processing happens locally in your browser using WebAssembly. Your files never leave your device.
