About Merge Audio
Merge Audio is a free online audio joiner that stitches several clips into one continuous MP3, right in your browser. Add your files, drag them into the order you want with the up and down arrows, and download a single combined track — no sign-up, no watermark, and no limit on how many files you join. It's built for stitching together things like voice memos, podcast segments, or the parts of a long recording into one clean file.
Because it re-encodes everything, it doubles as an audio-to-audio joiner across formats: drop in a mix of MP3, WAV, M4A and other files and they're joined seamlessly into one MP3, so you don't have to convert anything first. That makes it a handy free alternative to online joiners like Clideo, Flixier or Veed.io when all you need is to combine audio files back-to-back without paywalls or installing freeware. It only joins clips — it won't cut or trim them — so if you searched for a cutter and joiner, use it for the merge step.
Everything happens on your own device. The tool runs an in-browser build of ffmpeg, so your audio is processed locally and never uploaded to a server. The first merge downloads a one-time ~32 MB engine that's cached for instant runs afterward, and after that your files never leave your computer.
Frequently asked questions
- Is it free to use?
- Yes — it's completely free with no sign-up and no watermark. There's no cap on how many files you join or how long the finished track is.
- How do I join audio files together?
- Add the audio files you want to combine, put them in the right sequence with the up and down arrows, then merge. The tool joins them into one MP3 you can download.
- Is my file uploaded to a server?
- No. It runs an in-browser build of ffmpeg, so your file is processed entirely on your own device and never uploaded.
- Do I need to download or install any software?
- No. Unlike downloadable joiner freeware, this runs entirely in your web browser, so there's nothing to install and it works the same on Windows, Mac, ChromeOS or Linux.
- Is this a free alternative to Clideo, Flixier, or Veed.io?
- Yes. If you want a free online audio joiner like Clideo, Flixier or Veed.io but without paywalls, watermarks or accounts, this handles the core job — combining several audio files into one track — for free.
- Can I combine files that are in different formats?
- Yes. Files in different formats — MP3, WAV, M4A and more — are re-encoded and joined into a single MP3, so you can mix formats without converting them first.
- In what order are the files joined?
- Exactly the order shown in the list. Use the up and down arrows to rearrange the clips before you merge them.
- Is there a gap between the clips?
- No. The clips are joined back-to-back in the order you set, so they play as one continuous track with no silence added between them.
- Can I also cut or trim my audio here?
- This tool only joins clips — it doesn't cut or trim them. If you searched for an MP3 cutter and joiner, use this for the merging step and trim your clips beforehand in a separate editor.
- Can I join audio onto a video file?
- No. This is an audio-only joiner: it combines audio clips into a single MP3. It doesn't merge audio onto video or export a video file.
- What format is the merged file?
- The combined track is always exported as a single MP3, no matter which formats you started with.
- Why does the first run take a moment?
- The first time, it downloads a ~32 MB processing engine. That's cached afterwards, so later merges start instantly.
