How do I convert MP3 to AIFF using this tool?

Upload your MP3 file, choose AIFF as the output format, and click 'Convert'. The tool decodes the MP3's lossy audio data and writes it as an uncompressed PCM stream into an AIFF file. For batch conversion, select multiple MP3 files and download the resulting AIFFs as a ZIP archive. Files are processed in your browser, and you can adjust sample rate and bit depth before conversion.

Why should I convert MP3 to AIFF if it increases file size?

AIFF is an uncompressed audio format (PCM) that is natively supported by professional digital audio workstations (DAWs) like Apple Logic Pro, Pro Tools, and many hardware samplers. Converting MP3 to AIFF ensures compatibility with these tools without on-the-fly decoding, which reduces CPU load and avoids playback glitches. It also provides a stable container for further editing, since the audio is stored as raw samples rather than a compressed stream. Keep in mind that AIFF files are larger, but the conversion prevents additional quality loss during editing.

Does converting MP3 to AIFF improve audio quality?

No, AIFF cannot restore audio lost by MP3's lossy compression. The conversion decodes the MP3 into a pulse-code modulation (PCM) stream, which is what AIFF stores. The output will have the same sample rate and channel configuration as the original MP3, and the bit depth is typically set to 16-bit, matching CD quality. If the MP3 was encoded at a lower bitrate, the AIFF file will simply contain the decoded data without any enhancement. This is a lossless transcode from the lossy source; it's ideal for editing, not for recovering quality.
