It depends on the formats involved. If both MPEG and AAC use lossless compression, no quality is lost.

How long does it take to convert MPEG to AAC?+
Most conversions complete in seconds. Larger files (like high-resolution video) may take a bit longer depending on your computer's hardware. Since Filoshi runs locally, there is no upload or download wait time, which is significantly faster than online converters.
