How many files can I merge at once?

There is no hard limit on the number of files. However, very large merges may be constrained by your device's available memory.

Do all files need to be the same format?

No. You can mix MP3, WAV, OGG, AAC, and other browser-supported formats. They are all decoded to raw PCM before merging.

The tool automatically normalises all tracks to a common sample rate before joining them, so the output plays back correctly.

The merged file is always exported as an uncompressed WAV (PCM 16-bit), which is compatible with all audio software.

No. All merging happens entirely in your browser using the Web Audio API. Your files never leave your device.

Join multiple audio files in any order. Output is a single lossless WAV file.

Your audio never leaves your browser. All processing uses the Web Audio API locally.
