An audio converter in your right-click menu

Select a recording or a whole album, hold Shift, right-click and pick Audio. Flecto converts the files on your PC and saves them next to the originals. Voice notes and interviews never leave your computer.

Free to try. 10 conversions a week, no account needed.

What it converts

Flecto reads MP3, WAV, FLAC, M4A, AAC, OGG, OPUS, WMA, AIFF, ALAC and APE, and the soundtrack of any video it can open. It writes MP3, WAV, FLAC, AAC, OGG and OPUS.

When the audio is already in the format you pick, Flecto copies it without re-encoding. Audio work uses FFmpeg, which Flecto offers to download once; after that it works offline.
