How to use Audio Merger
Add your audio files
Click the box above or drag MP3, WAV, OGG or M4A files onto it. Add as many as you like — voice notes, clips, songs.
Arrange the order
Use the up and down arrows to put the files in the order you want them in the final audio. Remove any file with the ✕ button.
Merge and download
Press “Merge Audios”. Your files join into one audio file that downloads instantly — one file, in your order, with no gaps.
Example: Example: merge part1.mp3 (30 seconds) and part2.mp3 (45 seconds) and you get one merged.wav with 75 seconds — part 1 first, then part 2, with no gap between them.
About Audio Merger
Merging audio is one of the most common audio jobs: joining voice notes recorded in parts, combining clips into one podcast episode, or putting several song sections into a single file. AudioTools merges your audio right in your browser. There is no upload, no queue and no waiting room — the files are decoded on your own device and joined in the order you set, so a merge takes seconds even on a slow connection, and your recordings stay private.
The order is entirely yours: add the files, move them up or down, remove the ones you do not need, and merge. The result keeps every second of every file, in the order you set, and downloads as a WAV file, which opens in every audio app. Because everything runs locally, the tool works the same on a phone, a tablet or a computer — and it is free, with no account and no sign-up.
Frequently asked questions
How do I merge audio files online?
Add two or more audio files to the box above, arrange them in the order you want with the arrows, and press “Merge Audios”. The combined file downloads immediately.
Is merging audio free?
Yes. Merging audio on AudioTools is 100% free. There is no paid plan, no length limit and no watermark.
Do my audio files get uploaded?
No. The merge happens entirely in your browser. Your files never leave your device and nothing is stored on any server.
How many audio files can I merge at once?
There is no fixed limit. Very long files may take a few seconds to decode on older phones, but ordinary clips merge in seconds.
Will the merged audio keep the original quality?
Yes. The audio is joined at full quality — nothing is re-compressed. The result is a WAV file, which is uncompressed and sounds exactly like the originals.
Can I merge files of different formats?
Yes. MP3, WAV, OGG and M4A files can be mixed in one merge — the tool decodes each one and joins them in your order.
