Will converting OGG to AIFF improve audio quality?

No. OGG Vorbis is a lossy format — audio data was permanently discarded when the file was first encoded. Converting to AIFF does not restore that lost data. The benefit is that no additional quality loss occurs during conversion and the file is stored in an uncompressed container compatible with Apple tools.

What is the best free tool to convert OGG to AIFF?

FFmpeg is the most reliable option: run `ffmpeg -i input.ogg output.aiff` from the command line. For a graphical interface, fre:ac (Free Audio Converter), Audacity, and VLC are popular cross-platform choices. On macOS, Audacity provides a simple drag-and-drop workflow with AIFF export.

How large will the AIFF file be compared to the OGG?

AIFF is uncompressed, so it is typically 5–15x larger than an equivalent OGG file. A 5 MB OGG encoded at 160 kbps might yield a 30–50 MB AIFF file. The inspector on this page estimates the projected size based on your file's sample rate, channel count, and duration.

Is my audio file uploaded to a server?

No. All processing runs inside your browser using the Web Audio API. Your file is read into browser memory only and is never sent to any server. Refreshing the page clears all data.

What audio formats can the inspector read?

Any format your browser can decode natively: OGG Vorbis, MP3, WAV, AAC/M4A, FLAC (in supported browsers), and WebM. The inspector reads the decoded PCM properties — sample rate, duration, and channels — regardless of the source container.

What is the difference between AIFF and WAV?

Both are uncompressed PCM containers of nearly identical quality and file size. AIFF was developed by Apple and is the preferred format in macOS DAWs. WAV was developed by Microsoft and is more universal across Windows and Linux tools. For Apple-ecosystem work, AIFF is the natural choice; for cross-platform work, WAV has broader compatibility.

Does AIFF support metadata tags from the OGG source?

Yes. FFmpeg can transfer Vorbis comment tags (title, artist, album, etc.) to the AIFF ID3 container during conversion. Use `ffmpeg -i input.ogg -map_metadata 0 output.aiff` to ensure metadata is preserved. Verify tags in your target application after conversion.

OGG Vorbis vs. AIFF — What You Need to Know

OGG Vorbis (Lossy)

Discards audio data permanently at encode
Re-encoding to another lossy format degrades quality
Very small file size (3–10 MB typical)
Free, open-source, widely used in games and web

AIFF (Uncompressed)

Zero quality loss — bit-perfect PCM playback
Preferred for Logic Pro, GarageBand, and macOS
5–15x larger than equivalent OGG file
Less universal outside the Apple ecosystem

Copied!

Summary

Inspect your OGG file's metadata in the browser and get the exact FFmpeg command to convert it to AIFF — no upload required.

How it works

Drop any audio file (OGG, WAV, MP3, AAC) onto the inspector panel.
The Web Audio API decodes the file and reads its sample rate, duration, and channel count.
The inspector estimates the uncompressed PCM size and projected AIFF file size at 16-bit and 24-bit.
Copy the generated FFmpeg command or use a desktop GUI to perform the actual conversion.
Verify the output AIFF in your DAW or media player before deleting the source OGG.

Use cases

Import OGG game audio tracks into Logic Pro or GarageBand on macOS.
Archive an OGG music library in AIFF for Apple hardware compatibility.
Check a file's sample rate and channel layout before running a batch conversion.
Estimate the disk space an AIFF archive will require.
Verify audio properties without installing a desktop editor.
Teach yourself the difference between lossy OGG Vorbis and uncompressed AIFF.
Pre-screen files before a mastering or mixing session.
Confirm stereo vs. mono layout before sending tracks to a collaborator.
