Select your OPUS file
Click the upload area or drag your OPUS file straight onto it. You can drop several at once if you need to convert them all.
Check the target is MP3
The output format is already set to MP3. If you added several files and want a different format for each, switch to the "A format for each file" option.
Press Convert
Conversion runs without leaving your computer, so it starts instantly and never depends on your internet speed or on a queue at some server.

Hit Download and save your new MP3 file. If you converted several, you can grab them all together in a ZIP.

Frequently asked questions
Is converting OPUS to MP3 free?
Yes, entirely. No accounts, no daily file limit and no watermarks on the result. The site is funded by the ads on the page.
Are my files uploaded to a server?
No. The OPUS to MP3 conversion runs without uploading anything, without leaving your computer. The file never travels across the internet, so nobody can see it and there is no copy left to delete afterwards.
Is quality lost in the conversion?
MP3 uses lossy compression, so technically yes. We default to a high quality setting so the difference is not visible to the naked eye, in exchange for a much lighter file.
Can I convert several files at once?
Yes. Drop in as many as you like and they will be converted one after another. When they finish you can download them individually or all together in a ZIP.
Does it work on a phone?
Yes, on Android and iPhone, with no app to install. Just open this page in your phone browser.
