Almost anything: MP3, WAV, FLAC, OGG, M4A, AAC, Opus, AMR, WMA and more — including iPhone voice memos, WhatsApp notes and the audio track of MP4, MOV, MKV or WebM videos. Every format opens the same way, up to one hour per file. Output is MP3, WAV, FLAC or OGG.
There's no server-side limit since files aren't uploaded, and no watermark either. What there is, is a length ceiling: about an hour per file, the same for every format, because the work happens in your browser's memory. Free refuses a file past the hour. cut.audio Pro splits it into parts in the browser; on Windows, the same Pro lets cut.audio Studio open it whole (up to four hours).
