Guide updated:
Merge several audio or MP3 files into one track online.
Practical instructions with desktop and phone screenshots, short demonstrations and answers to common questions.
Before you start
Keep the original file and use the small public demonstration file linked below. Check the supported formats and limits in the service before choosing your own file.
Try with a demonstration file — audio.mp3
These small files were created for this guide and contain no personal data.
Step-by-step instructions
- Open the tool using the button next to the video. Keep the default mode unless the next step specifies a different one.
- Choose the demonstration file. Wait until its name or preview appears, then review the available settings.
- Choose the options required for your task. Open the question marks for explanations; the values used in the demonstration are examples.
- To perform the full operation, press the main processing button. If the service asks you to sign in or confirm a price, check the current terms before continuing.
- Wait for a successful result, inspect it and save the output before leaving the page. A settings demonstration is not a completed processing result.
On a computer
Use the file picker or drag the demonstration file into the upload area. Wait until the source is ready, then review the options and main action.
On a phone
Choose the demonstration file from Files or your gallery. Wait for the file to finish loading and scroll to the settings. Keep the tab open while working.
In Safari on iPhone, open the sharing menu and choose Save to Files if the result opens in a new tab. In Android Chrome, check Downloads. Keep this tab open until processing finishes.
For a better result
Merge several audio or MP3 files into one track online. Wait for a successful result, inspect it and save the output before leaving the page. A settings demonstration is not a completed processing result.

Questions and troubleshooting
Does this demonstration use my real data?
No. The recording uses public example values created for the guide. The service operates on the input you enter in your own browser.
What should I check before relying on the result?
Merge several audio or MP3 files into one track online. Wait for a successful result, inspect it and save the output before leaving the page. A settings demonstration is not a completed processing result.
If you see a message that the service is overloaded, wait and try again later. A failed attempt does not mean that your source file has changed.
