M4A Compressor
M4A Compressor helps you reduce the size of an M4A audio file by re‑encoding it to AAC in an M4A container with a lower target bitrate. Instead of guessing export presets in a full audio editor, you upload a file, choose a bitrate, and optionally set sample rate and mono/stereo channels to match the content type. For podcasts and voice notes, mono at 64–96 kbps often keeps speech clear while cutting size dramatically. For music, keeping stereo and using higher bitrates (128–256 kbps) usually preserves detail better. The tool runs the actual compression on the backend using FFmpeg so your browser stays responsive for larger files. An optional AI Assistant (triggered only when you click) can suggest safe settings based on whether your audio is speech, podcast, music, or mixed, and whether you care most about smallest file size or highest quality.

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.
