Add your OGG file
Drop one or more .ogg files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
OGG to AIFF

Re-encoding .ogg audio as .aiff changes how the sound is compressed and which players will accept it. An .ogg file almost always means Vorbis-compressed audio in the Ogg container, the free-software world's answer to MP3. The .ogg extension originally covered any Xiph media; audio kept the name when video moved to .ogv, and game developers and Wikipedia still lean on it heavily.
An .aiff file is Apple's Audio Interchange File Format, storing uncompressed PCM audio much as WAV does on Windows. Mac-based studios have exchanged .aiff masters for decades, and Logic Pro sessions and sample libraries remain full of them. For this route the practical draw is bit-perfect audio identical in fidelity to WAV and loop and marker metadata that samplers actually read — balanced against as bulky as any uncompressed format, which is worth knowing before you commit a large batch.
Why convert OGG to AIFF?
The practical trigger for this conversion is usually a mismatch: with .ogg, apple's Music app and iOS offer no native playback. Switching to .aiff buys you bit-perfect audio identical in fidelity to WAV, which is why it is the better fit for delivering masters from macOS-based studios. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
OGG vs AIFF at a glance
| Aspect | Ogg audio (.ogg) | Audio Interchange File (.aiff) |
|---|---|---|
| Format type | Lossy — discards detail it judges invisible to shrink files | Lossless — every pixel or sample is preserved exactly |
| How it stores data | vorbis is an MDCT-based lossy codec tuned through a quality scale (-q) rather than fixed bitrates | classic AIFF stores big-endian PCM, the opposite byte order from WAV, in COMM and SSND chunks |
| Strongest at | shipping game audio assets without codec royalties | delivering masters from macOS-based studios |
| Weak spot | apple's Music app and iOS offer no native playback | as bulky as any uncompressed format |
| Metadata | vorbis comments, the flexible key=value system shared with FLAC and Opus, plus METADATA_BLOCK_PICTURE for embedded cover art | nAME, AUTH, and ANNO chunks provide basic text, marker and instrument chunks store loop data, and an ID3 chunk is a common unofficial extension used by iTunes |
Pick AIFF as the output
Select .aiff in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if AIFF is selectable, the route is real and validated.
Convert on your device
Press Convert. The transcode runs on an FFmpeg engine compiled to WebAssembly, so the audio never leaves your device.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid AIFF file. Outputs keep the original filename with the .aiff extension.
OGG to AIFF questions, answered
Will converting OGG to AIFF lose quality?
No new loss is introduced — since ogg is lossy-oriented and aiff is lossless-oriented, everything the .ogg file still contains is carried over exactly. What was already discarded by the original lossy encode cannot be recovered, though; converting to .aiff does not "restore" quality.
Is it private to convert OGG files here?
Yes — the .ogg file is processed inside your browser tab and never uploaded. The transcode runs on an FFmpeg engine compiled to WebAssembly, so the audio never leaves your device. Close the tab and the file is gone from memory.
Where will the AIFF file work?
macOS and all serious audio software open .aiff without hesitation, and Windows editors generally support it even though WAV is their default. Browsers offer partial support at best, and the format's size makes it a poor web choice regardless.
Will the AIFF file be bigger or smaller than my OGG?
Larger, sometimes much larger. A lossless .aiff must store every pixel or sample the decoder produced, without the perceptual shortcuts .ogg used. Use this route for editing headroom, not for saving space.
What happens to the metadata in my OGG file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, vorbis comments, the flexible key=value system shared with FLAC and Opus, plus METADATA_BLOCK_PICTURE for embedded cover art; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert AIFF back to OGG?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .ogg → .aiff → .ogg is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
