Common questions
Does converting to FLAC improve sound?
No. FLAC preserves the decoded audio without further loss, but cannot restore detail removed by an earlier MP3 or AAC encode.
Do my files leave my device?
Files are processed inside this browser. The site downloads its processing software, but your selected files are not sent to a conversion server.
Which files can I use?
MP3, WAV, FLAC, AAC, M4A, OGG, Opus, AIFF and WebM audio files are accepted. The codec inside a file must also be supported.
How large can a file be?
Select up to 100 images per batch, or one audio or video file per job. There is no fixed file-size or processing-time quota. Available memory, browser support and your device determine what can be processed. Large batches offer individual downloads to avoid an additional ZIP copy.
