Convert Audio & Video to AIFF Online — Free AIFF Converter
Use this free online AIFF converter to transform audio and video files from a wide range of formats into the high-quality AIFF format — no software installation or account required.
What is AIFF?
AIFF (Audio Interchange File Format) is an uncompressed audio container developed by Apple in 1988, based on the IFF standard originally created by Electronic Arts. Like WAV, it stores raw PCM audio data, which means files retain every detail of the original recording without any lossy compression. AIFF files typically use the .aiff or .aif file extension and support standard bit depths of 16-bit and 24-bit at sample rates up to 192 kHz.
A compressed variant, AIFF-C (also known as AIFC), exists but is far less common; the plain AIFF format remains the standard choice when lossless quality is the priority.
Why convert to AIFF?
AIFF is widely used in professional audio production, particularly on macOS and in Apple-ecosystem software. Common reasons to convert a file to AIFF include:
- Professional editing: Digital audio workstations such as Logic Pro and GarageBand natively read and write AIFF, making it the natural exchange format in Apple-centric workflows.
- Lossless archiving: Because AIFF stores uncompressed PCM data, no audio quality is lost compared to formats like MP3 or AAC.
- Broad hardware compatibility: Many hardware samplers, mixers, and CD authoring tools accept AIFF as a standard input format.
- Mastering and post-production: Studios often require lossless deliverables; AIFF fulfils that requirement alongside WAV.
Supported input formats
The converter accepts a broad range of audio and video source files, including common formats such as MP3, AAC, OGG, FLAC, WAV, WMA, M4A, OPUS, RA, MP2, and many video containers (MP4, AVI, MOV, MKV, and more). You can upload a file from your device or supply a direct remote URL for conversion.
Frequently asked questions
Is this AIFF converter free to use?
Yes, the tool is completely free. You can convert files to AIFF without creating an account or paying any fee.
What is the difference between AIFF and WAV?
Both formats store uncompressed PCM audio and deliver identical audio quality. AIFF was developed by Apple and is the preferred lossless format on macOS, while WAV was developed by Microsoft and is more common on Windows. Either format is an excellent choice for lossless audio work.
Can I convert video files to AIFF?
Yes. The converter can extract the audio track from video files such as MP4, AVI, MOV, and MKV and save it as an AIFF file.
What happens to my file after conversion?
Uploaded and converted files are processed on the server and then deleted automatically. They are not stored permanently or shared with third parties.
Do I need to install any software?
No installation is needed. The conversion runs entirely in the cloud; you only need a web browser to upload your file and download the result.
