Does converting AAC to OGG lose quality?
Yes. Both AAC and OGG are lossy formats. Transcoding between two lossy formats causes some quality loss. Higher bitrates in the output minimize audible degradation.
Is OGG better than AAC?
At equivalent bitrates, they are comparable in quality. AAC has wider hardware support while OGG is patent-free and preferred in open-source contexts.
Are my files uploaded to a server?
No. All conversion happens in your browser using the Web Audio API. Your files never leave your device.
Can I convert M4A files with this tool?
Yes. M4A is an AAC audio file in an MP4 container. This tool handles M4A files the same as AAC files.
Which devices support OGG?
OGG is supported by modern web browsers, Android devices, Linux systems, and many desktop media players. It has limited support on Apple devices and some older hardware.
Can I convert multiple files at once?
This tool converts one file at a time. Process each file separately for batch conversion needs.
