Opus recordings arrive from chat apps and web calls, but a Mac editing session wants AIFF, not a streaming codec. This free opus to aiff converter decodes an Opus file and rewrites it as an uncompressed AIFF, so voice notes and call recordings can be trimmed and mixed in Logic Pro, GarageBand or another Mac editor. Everything runs in your browser, so your file is never uploaded and no signup is needed. The honest limits: the AIFF output is 16-bit PCM, Opus compression detail does not come back, and if your browser cannot decode Opus at all, the tool shows a plain error instead of a broken file.
How to use this opus to aiff converter
From a chat-codec recording to a Mac-ready AIFF.
Choose a .opus or .ogg Opus file, a voice note or a call recording.
Decoding and AIFF writing happen on your own device, so nothing is uploaded.
Save the uncompressed file and import it into your Mac editor.
Why this opus to aiff converter fits Mac editing
Opus is built for sending. AIFF is built for the Mac timeline.
Voice notes and call recordings become ordinary AIFF clips that sit alongside Mac-recorded material.
Once uncompressed, trims, fades and mixes no longer stack another compression round onto Opus audio.
The decoded sample rate and channel layout are carried into the 16-bit PCM AIFF.
Personal voice recordings are converted on your own device and never uploaded.
OPUS to AIFF Converter FAQs
Short, direct answers to the questions readers ask most.
For Mac workflows. Both are uncompressed, but AIFF is the format macOS editors prefer, so it slots into Logic Pro and GarageBand sessions most naturally.
No. Opus compression already discarded detail, and that detail cannot be recovered. The AIFF preserves what the Opus file still contains.
You get a plain error, not a broken file. Opus decoding works in current Chrome and Firefox; try one of those if your browser fails.
Yes, much larger. Opus is highly compressed for sending, while AIFF stores every sample uncompressed for editing.
Yes. It runs entirely in your browser, with no account, no signup and nothing uploaded.
