AIFF to OGG Converter

AIFF vs OGG — Which Should You Convert To?

If you are sitting on a folder of AIFF masters, the real question is not "AIFF or OGG" but "which one do I keep and which one do I ship." AIFF is uncompressed Apple PCM: bit-for-bit fidelity, roughly 10 MB per minute, and awkward anywhere outside a studio. OGG is a compressed delivery format that plays in the overwhelming majority of browsers and in every major game engine at roughly a tenth of the size. Short answer: convert to OGG for games, web playback, and open-source pipelines — and keep the AIFF as the master you edit from.

AIFF and OGG Side by Side

When OGG Is the Right Target

• You are building a game. Godot's import documentation lists exactly three audio formats — WAV, Ogg Vorbis, and MP3 — and recommends Ogg Vorbis for music, speech, and long sound effects. Shipping AIFF into an engine just means the engine compresses it for you, usually to Vorbis anyway.
• The audio has to stream on a web page. Vorbis in an Ogg container is a first-class HTML5 audio source in Chrome, Firefox, and Edge, and in Safari from version 18.4.
• You need a royalty-free format. Xiph publishes Vorbis as an open specification with no licensing fee, which is why it became the default compressed format across open-source software.
• Storage or bandwidth is the constraint. A hundred AIFF sound effects that occupy a gigabyte will typically fit in around a hundred megabytes as Vorbis.

When to Keep the AIFF Instead

• It is a master you will edit again. Every lossy encode is one-way. Edit the AIFF, export a fresh OGG whenever you need one.
• You want a smaller file with zero quality loss. That is a lossless-compression job, not a Vorbis job — use AIFF to FLAC, which typically halves the size with every sample intact.
• The file has to open on older Apple hardware without a third-party player. Older iOS, iTunes, and pre-18.4 Safari builds do not handle .ogg reliably; AIFF to MP3 is the safe fallback.
• You are starting a new project with no legacy Ogg constraint. Xiph's own published listening tests show Opus beating libvorbis at both 64 kb/s and 96 kb/s, so AIFF to Opus is worth a look.

Which Codec Goes Inside the Ogg File

How to Convert AIFF to OGG

1. Upload Your AIFF File: Drag and drop your .aiff or .aif file onto the page, or click "+ Add Files" to browse. Queue several files and they all convert with the same settings.
2. Keep Vorbis or Change the Audio Codec: Open Advanced Options. The .ogg output encodes Vorbis by default; the Audio Codec list also offers Opus, FLAC, and Speex.
3. Set Quality Preset, Bitrate, or Size: Under File Compression, choose a Quality Preset (Highest through Lowest), pick a value under Variable Bitrate or Constant Bitrate, type a rate under Custom Bitrate, or cap the result with Specific file size or File Size Percentage. Audio Channel, Audio Sample Rate, and Trim stay on their original values unless you change them.
4. Convert and Download: Click Convert and save your .ogg file, or grab a batch as a ZIP. No sign-up, no watermark.

Frequently Asked Questions

Will I lose audio quality converting AIFF to OGG?

Yes, and it is permanent — AIFF is lossless and Vorbis is lossy. But this is the best case for a lossy encode: the encoder is reading an uncompressed PCM master, so it is one clean generation with no artifacts inherited from an earlier compression. Around 128 kbps most listeners cannot pick the Vorbis file out of a blind comparison on typical music. Keep the AIFF as your archival master and treat the .ogg as the copy you distribute.

What bitrate should I use for OGG Vorbis?

Xiph specifies Vorbis at 16–128 kbps per channel, and the Variable Bitrate list on this page runs 48K to 384K. For stereo music, 128K–192K is the comfortable zone. Short game sound effects and ambience usually hold up at 64K–96K, which matters when you are packing hundreds of them. Above 256K you are mostly buying file size: the source is uncompressed, so there are no inherited artifacts that a higher bitrate could rescue.

Should I pick Vorbis or Opus inside the .ogg file?

Pick Vorbis when something else has to read the file. Godot documents Ogg Vorbis as one of its three supported import formats, and a great deal of game and internet-radio tooling assumes Vorbis when it sees .ogg. Pick Opus when you own the playback side: Xiph's published listening tests put Opus ahead of libvorbis at 64 kb/s and 96 kb/s, so it gives you smaller files at equal quality. If Opus is the goal, AIFF to Opus writes a .opus file that players recognise immediately.

Why won't my OGG play on my iPhone or in the Music app?

Apple was the long-standing gap in Ogg support. Browser-compatibility tracking shows Safari only reaching full Ogg Vorbis support at version 18.4, and older iOS and iTunes releases do not treat .ogg as a native music format at all. On those systems you need a third-party player such as VLC — or you convert to something Apple ingests natively, like AIFF to M4A or AIFF to MP3.

How much smaller will the OGG file be than the AIFF?

We size this from the arithmetic rather than guesswork. A 16-bit / 44.1 kHz stereo AIFF is a fixed 1,411 kbps — about 10 MB per minute — because uncompressed PCM has no content-dependent variation. Vorbis at 128 kbps is roughly 0.9 MB per minute, so a four-minute track goes from about 40 MB to under 4 MB, a reduction of roughly 90%. Choosing 192K instead lands near 1.4 MB per minute. If you need to hit an exact number, Specific file size works backwards from the size you type.

Will my track title, artist, and other tags survive?

Do not count on it. AIFF stores metadata in optional chunks that many tools write inconsistently or skip entirely, whereas Ogg has a proper tagging system in Vorbis comments. The reliable workflow is to convert first and then tag the .ogg in a player or tag editor, especially for a batch destined for a music library. Loop points and instrument chunks that some AIFF files carry are an AIFF-specific feature and do not have a Vorbis equivalent.

Can I convert the OGG back to AIFF later?

You can rebuild the container — OGG to AIF writes an Apple-side PCM file — but it restores the format, not the fidelity. What Vorbis discarded during encoding is gone, and the resulting AIFF will be full-size again while still sounding like the Vorbis file. Round-tripping is only worth doing when a tool refuses to open .ogg at all. For a genuine lossless copy you can edit, keep the original AIFF.

Are my uploaded files kept private?

Files are uploaded over an encrypted connection, converted on our servers, and deleted automatically a few hours after conversion — never shared, never made public, with no sign-up and no watermark. The practical limit on a large batch of AIFF masters is upload time, since uncompressed audio is bulky before it is converted, not a queue or an account tier.
