Format description
AAC files are audio files using Advanced Audio Coding compression. AAC is a lossy format, meaning the audio quality remains almost the same as the original source. The slight loss leads to the audio files taking up less space, which makes them ideal for music streaming or when bandwidth is limited. AAC is superior to MP3 for handling frequencies above 16 kHz. The encoding efficiency for transient and stationary signals is also better when compared to MP3.Common questions about converting to AAC

Is converting to AAC safe with MConverter?
For cloud-based conversions, MConverter encrypts your files using the latest technologies, such as TLS 1.3 and HSTS. They are transmitted securely to our cloud service provider’s EU-based data center, which holds internationally recognized ISO 27001 and SOC 2 certifications. There, each conversion is processed in a separate, isolated environment. This technique further reduces the risk of a malicious file impacting other conversions.
Four hours after the conversion is complete, your files are automatically deleted from MConverter’s systems. You can also permanently delete your files immediately after finishing the conversion with the trash icon.
When converting on-device, your files never leave your device. MConverter processes them locally. Note: on-device conversions are not yet available for some hardware-intensive formats.
For both cloud and on-device conversions, your files are never scanned or shared with third parties for marketing purposes.
