Fast, secure MP2 to AIFF conversion. No registration required.
Starting point: MP2 is an audio format with specific trade-offs between file size, bitrate flexibility, and device support. Natural next step, a AIFF. Need a AIFF version of a MP2 recording for a podcast host, audio book platform or DAW that refuses the original container? Drop the file above and our encoder produces a clean AIFF you can drag straight into the destination tool. Metadata such as title, artist and cover art travels with the audio. A quick refresher — MP2 is an audio format with specific trade-offs between file size, bitrate flexibility, and device support. By contrast, AIFF is Apple's uncompressed Audio Interchange File Format, the macOS equivalent of WAV.
MPEG Layer 2 Audio
Source formatMP2 (MPEG-1 Audio Layer II) is an audio compression standard that preceded MP3. It remains the standard audio format for digital radio broadcasting (DAB) and digital television (DVB) due to its lower encoding delay and better error resilience.
AIFF Audio
Target formatAIFF is Apple's uncompressed audio format, equivalent to WAV in the macOS ecosystem. It stores CD-quality PCM audio and is widely used in professional audio production on Apple hardware.
Why convert MP2 to AIFF
MPEG Layer 2 Audio is great in its own niche, but AIFF Audio is either more universally playable or better suited to the device you are targeting. Converting lets you ship the audio without asking listeners to install a codec. The loss in quality between the two is negligible at sensible bitrates.
HOW TO CONVERT
MP2 → AIFF
Upload the MP2
Drop or select your MP2 file. The upload is encrypted and the file is queued for conversion.
Transcode via FFmpeg
FFmpeg decodes the MP2 stream to PCM internally, then re-encodes as AIFF at the bitrate you select.
Download the AIFF
The AIFF is delivered as a direct download; metadata and cover art transfer automatically where possible.
Common Use Cases
Share across platforms
Send AIFF files to anyone without worrying about whether they have the right software for MP2.
Embed in documents
Drop AIFF output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
AIFF often produces smaller files than MP2 for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
MP2 vs AIFF — Strengths and limitations
What each format does best, and where it falls short.
MP2 Strengths
- Robust against transmission errors — designed for broadcast.
- Lower CPU demand than MP3 — mattered for 1990s receivers.
- Universal playback via every audio player.
- ~30 years of broadcast field experience.
Limitations
- Worse compression than MP3 at the same quality.
- Largely obsolete for new content.
- Patent licensing never fully cleared (though most expired by 2017).
AIFF Strengths
- Lossless and uncompressed — bit-exact audio reproduction.
- Native to macOS and all Apple Pro Audio apps.
- Simple structure — trivially parsed by audio libraries.
- Supports up to 32-bit float, 192 kHz, and multi-channel audio.
- Rich metadata via named chunks (annotations, markers, MIDI).
Limitations
- Enormous file sizes — 10 MB per minute at CD quality.
- No built-in compression — use FLAC for lossless with smaller files.
- Big-endian byte order confuses tools written on little-endian hardware.

- Full album (CD, 10 tracks) 450 MB
Quality & Compatibility
Lossy-to-lossy transcoding (most cross-format audio jobs) loses a tiny amount of quality on each pass — usually inaudible at our default VBR ~190 kbps for music or 96 kbps for speech. Lossy-to-lossless conversions freeze the existing quality but cannot improve it; lossless-to-lossy is only as good as the target bitrate you choose.
Tips for Best Results
- Pick 128 kbps for podcasts and voice, 192–256 kbps for music, 320 kbps only if the audio will be edited further downstream.
- Keep the MP2 master alongside the AIFF — re-encoding a lossy format twice accumulates audible artefacts.
- For mono voice content, convert to mono AIFF explicitly to halve file size without any quality loss.
Frequently Asked Questions
Lossy-to-lossy conversions (most combinations) re-compress the audio, which technically introduces some loss. At a 192 kbps or higher target it is inaudible on normal equipment. Lossy-to-lossless conversions freeze the existing quality but cannot improve it; lossless-to-lossy transcodes are only as good as the target bitrate you choose.
For voice content (podcasts, audiobooks, lectures) 128 kbps is indistinguishable from higher bitrates. For music, 192-256 kbps covers most listening; 320 kbps is the ceiling for AIFF and the right choice for audio you plan to edit further. Above that, prefer a lossless target instead.
Yes. Title, artist, album, year and cover art travel from the MP2 container to the AIFF container automatically where both formats support them. If a tag field has no AIFF equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
