Drop your MP3 here
Anywhere on this page works
Turn MP3 files into OPUS in this browser tab. Drop the file on the card above, check the output options under it, and download the OPUS as soon as it is ready — there is nothing to install.
No account is needed, nothing is watermarked, and the upload is deleted once your download finishes.
Drop the file in, or pull it from Drive, Dropbox, OneDrive or a URL.
Output is already locked to OPUS. Quality, size and metadata options sit under the card.
Download it straight away. Nothing is watermarked and no account is needed.
Every format we can turn into opus audio, each on its own page.
MP3 does not have to become OPUS. Here is everything else it can be.
