Frequently asked questions
Can I merge files in different formats?+
Yes. You can mix MP3, WAV, OGG, and other supported formats. The tool decodes each file and re-encodes the merged result into your chosen output format.
Is there a limit on how many files I can merge?+
There is no hard limit. You can add as many files as your device memory allows. Most browsers handle dozens of typical-length tracks without issues.
Can I add silence between tracks?+
Yes. You can insert a gap of configurable duration between any two tracks, or use crossfade to blend the end of one track into the start of the next.
Are my files uploaded anywhere?+
No. All merging runs entirely in your browser using WebAssembly. Your audio files never leave your device.
What output formats are available?+
You can export the merged result as MP3, WAV, OGG, or AAC. Choose the format that best fits your needs before downloading.
