-
Upload your OPUS audio file from your device or cloud storage
-
Choose AIFF as the output file format
-
Click the convert button to start the conversion process
-
Download the converted AIFF audio file for professional use
-
Import the AIFF file into your digital audio workstation or editing software

Archive consumer audio originally in OPUS to lossless AIFF format for long-term storage
-
Exchange high-fidelity multichannel audio between digital audio workstations using AIFF
Tips & Best Practices
-
Remember that converting from lossy OPUS to AIFF preserves decoded audio but does not restore original quality
-
Be prepared for significantly larger AIFF files due to uncompressed data
-
Resample OPUS audio if higher sample rates are needed before conversion
-
Check metadata after conversion as some OPUS tags may be lost or incomplete in AIFF
Limitations
-
AIFF files produced are much larger than original OPUS due to uncompressed audio format
-
Conversion does not recover audio quality lost from OPUS lossy compression
-
OPUS internal sampling rate capped at 48 kHz limits audio fidelity for high-res projects
-
Metadata support varies and may not fully transfer between OPUS and AIFF formats
Frequently Asked Questions
-
Why convert OPUS files to AIFF format?
-
Converting OPUS to AIFF allows for uncompressed audio preserving full fidelity, which is ideal for professional editing, mastering, and archival purposes.
-
Will converting from OPUS to AIFF improve the audio quality?
-
No, since OPUS is a lossy format, converting to AIFF preserves the decoded audio without restoring original pre-compression quality.
-
Are AIFF files larger than OPUS files?
-
Yes, AIFF stores uncompressed PCM audio which results in much larger file sizes compared to the compressed OPUS format.
