This free online tool lets you volume MP3 audio files quickly and easily, without installing any software.
What audio formats are supported?
+
We support MP3 and many other audio formats. You can also convert between different formats.
Is there a file size limit for MP3 files?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Will this affect the quality of my MP3 file?
+
Our tool is designed to maintain the best possible quality while volumeing your MP3 files.
Can I volume multiple MP3 files at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Is the Volume MP3 tool free to use?
+
Yes, our Volume MP3 tool is completely free for basic usage. No registration required.
Does it work on mobile endpoints
+
Yes, our converter is fully responsive and works on smartphones and tablets. You can convert files on iOS, Android, and any other mobile platform with a modern browser.
Which browsers are covered
+
Our converter works with all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. We recommend keeping your browser updated for the best operation.
Are my files kept private and confidential
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
What if my fetch doesn't start
+
If your fetch doesn't start hands-free, try clicking the download button again. Make sure pop-ups are not blocked, and check your browser's download folder. You can also right-click the download link and check 'Save As'.
Will the standard be preserved
+
It depends on the formats. A lossless target such as PNG, WAV or FLAC keeps what the source holds; a lossy target such as JPG, MP3 or MP4 is usually re-encoded, which trades some detail for a smaller file.
Do I need to create an login
+
No account is required for basic usage. You can process files immediately. Creating a free account gives you access to your conversion history and additional features.
