AAC Converter
AAC Converter lets you turn AAC and other common audio files into web-friendly formats like MP3, M4A, WAV, and OGG without guessing which export preset to use in a full audio editor. You upload a track once, choose an output format, adjust bitrate, sample rate, and channel layout, and immediately download a new file that is easier to share, host, or embed. The interface is tuned for spoken-word and everyday listening scenarios where you want to keep speech natural and music clear while avoiding oversized, high-bitrate masters that waste bandwidth. For users who are unsure which settings to pick, the optional AI Assistant can suggest safe defaults based on file length and use-case without exposing any model details in the browser.

M4A Converter
M4A Converter is a focused audio conversion tool for people who regularly work with M4A files and need them in other everyday formats without learning a full audio editor. You upload a single file—typically an M4A track exported from a phone, recorder, or editing app—choose an output such as MP3, M4A, WAV, OGG, or FLAC, and adjust simple controls for bitrate, sample rate, and mono or stereo channels. The backend uses FFmpeg to decode the source and re-encode it into the chosen format while reporting both the original and converted sizes so you can see the impact of your settings. This makes it easy to create small MP3 copies for sharing, lossless WAV or FLAC files for editing and archiving, or compatible M4A versions for mobile players, all from the same interface. When you are unsure which path to take, an optional AI Assistant can recommend a target format and quality based on your goal (sharing, speech, archiving, or compatibility) without exposing any model details in the browser.
