An audio joiner that keeps your files private
Merging voice notes, podcast segments, or music clips usually means uploading everything to a website and waiting. This tool does the joining directly in your browser using the Web Audio API — your files are never sent anywhere, and there's no queue to wait behind.
Add your files in any order, use the arrows to arrange them exactly how you want, optionally add a short gap between clips, and export the result as MP3 or WAV.

Voice memos

Frequently asked questions
Is this audio joiner free?+
Yes — join as many files as you want, with no sign-up and no limits.
Are my files uploaded to a server?+
No. Every file is decoded and joined locally in your browser and never leaves your device.
Can I join files that are in different formats?+
Yes — you can mix formats like MP3 and WAV in the same batch. They're automatically matched to the same sample rate and channel layout before joining.
Can I reorder the clips after adding them?+
Yes — use the up and down arrows next to each file in the list to set the exact order before joining.
Why only MP3 and WAV as export formats?+
These have reliable, lightweight browser-based encoders. Other formats need heavier encoders that behave inconsistently across browsers, so we focused on getting these two right.
