AIFF to MP4 FAQs
The main reason is to upload your audio to video-sharing platforms. Websites and social media apps like YouTube, Instagram, and Facebook require a video format for all uploads. This converter wraps your high-quality AIFF audio in a universally supported MP4 container so you can share it on these sites.
Your audio will be converted from the lossless AIFF format to the high-quality, but lossy, AAC format, which is the standard for MP4 files. While AAC provides excellent sound, this is a compression step, meaning the final audio will no longer be a perfect, bit-for-bit copy of your uncompressed original.
The MP4 file that you download will contain a simple black screen that plays for the entire duration of your audio track. Our converter automatically generates this blank video stream because a video component is required to create a valid, playable MP4 file.
No, this is a direct format converter, not a video editor. It is designed to add a blank video track only. To create a video that displays a static image, such as your album cover art, while the audio plays, you would need to use a dedicated video editing application.
The final MP4 file will be significantly smaller than your source AIFF file. This is because the massive file size reduction from compressing the huge, uncompressed AIFF audio track far outweighs the small amount of data that is needed to add the simple black video screen.
