Frequently asked questions
Which audio formats are supported?
MP3, FLAC, and Ogg files can be converted to M4A.
Is quality preserved when converting FLAC to M4A?
No. Lossless FLAC is re-encoded with AAC, a lossy codec, so the quality may differ. In return, the file size shrinks significantly.
Are album art and tags copied?
No. Only the first audio track is used; album art and original metadata are not copied into the output.
Which devices can play M4A?
Apple devices such as iPhones and Macs, most modern smartphones, and browsers can play M4A.
Is my audio file sent anywhere?
No. Your file never leaves your device. The conversion runs inside your browser and nothing is uploaded.
