Frequently asked questions
Will converting MP3 to WAV restore lost quality?
No. WAV stores the decoded sound without another lossy encoding step, but frequencies and detail discarded when the MP3 was made cannot be reconstructed.
Where are my files processed?
These tools upload files for server processing. Files expire after 24 hours and are then scheduled for cleanup. Continue Editing remembers files in this browser tab until refresh. Processing does not use your credits.
Which formats and limits apply?
Audio input: MP3, WAV, FLAC, M4A, AAC and OGG. Video to MP3 accepts MP4, MOV, MKV and WebM with an audio track. Guests: 25 MB; signed-in users: 100 MB. Up to 10 minutes, mono or stereo. Audio outputs are MP3, WAV, FLAC, M4A and OGG; extraction and compression export MP3. OGG uses Opus at 48 kHz; other outputs use 44.1 kHz and does not preserve tags or artwork.
Expect a larger output file
PCM WAV does not use MP3's lossy compression, so output can grow substantially. A larger WAV is a compatibility choice, not proof of better source quality. Check your destination's WAV requirements before exporting.
