Drop your OPUS here
Anywhere on this page works
Turn OPUS files into M4A in this browser tab. Drop the file on the card above, check the output options under it, and download the M4A 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 M4A. 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 apple audio, each on its own page.
OPUS does not have to become M4A. Here is everything else it can be.
