Merge Audio
Add several audio files, drag them into the order you want, and merge them into a single track. Everything runs in your browser, so your files are never uploaded.
How to merge audio files
- Add the audio files you want to join (drop several at once, or add more after).
- Reorder them with the up/down arrows until the sequence is right.
- Pick MP3 or WAV, click Merge, and download the combined track.
About merging audio
Merging joins audio files one after another into a single continuous track — useful for stitching together voice memos, podcast segments, song parts or sound effects. The order matters, so you can rearrange the list before merging.
Files are decoded with the Web Audio API and joined sample-for-sample, then re-encoded to MP3 or WAV. Mixed sample rates are handled automatically (each file is resampled to a common rate on decode), and mono files are placed across both channels so they sit alongside stereo ones. It all happens locally — nothing is uploaded.
Frequently asked questions
How many files can I merge?
As many as you like — add them in batches, reorder the list, and they’re joined in that order. Very large totals are limited only by your device’s memory.
Can I change the order?
Yes. Each file has up and down arrows so you can arrange the exact sequence before merging.
What formats can I merge?
Any audio your browser can decode — MP3, WAV, M4A, AAC, OGG, FLAC and more — and the merged result downloads as MP3 or WAV.
Are my files uploaded?
No. Merging happens entirely in your browser, so your audio never leaves your device.
