Audio Merger
Combine multiple audio tracks into one seamless file in seconds. Upload as many clips as you need, reorder them by drag-and-drop, and export as a single MP3 or WAV. Perfect for creating DJ mixes, podcast intros, or stitching together song parts. You can mix and match file formats freely — the tool automatically normalizes everything into one consistent output so you don't have to convert files individually first. This makes it a natural fit for podcasters who record intro, main content, and outro segments separately, or for anyone assembling a mixtape from multiple source files. Playback order updates live in the list as you drag, so you can preview the flow before committing to the final export, and the whole process happens on-device without uploading anything.

FAQ
How many files can I merge?+
As many as your browser memory allows! Usually, 10–20 files work perfectly.
Can I merge different formats?+
Yes. Whether it's MP3, WAV, M4A, OGG, or FLAC, we'll automatically unify the format for you.
Can I change the order of the files?+
Yes. Just drag and drop the files in the list to rearrange them however you like.
Is there a total length limit?+
There's no strict length limit, but keep in mind that too many large files can consume significant browser memory.
Can I add silence between clips?+
Not in the current version. We merge files back-to-back. Silence insertion is on the roadmap!
Is this good for merging podcast episodes?+
Definitely. It's perfect for stitching your Intro, Main Content, and Outro together.
The volumes of the merged files are inconsistent.+
Use our Volume Booster's LUFS normalization on each file first to match their loudness before merging.
Will merging MP3s cause quality loss?+
Since MP3 is a lossy format, there is a tiny amount of re-encoding loss. For pristine quality, export as WAV.
How long does it take to merge?+
It's super fast! Usually just a few seconds for 10 typical MP3 files.
What happens if I leave the page during merging?+
The process will stop. Please keep the tab open until the merge is complete.
