Convert Audio Between MP3, WAV, AAC, OGG, and FLAC
Drop any audio file and CipherForces converts it to your target format using FFmpeg compiled to WebAssembly. All processing happens in your browser — your audio never uploads.

Frequently asked questions.
How do I convert audio between MP3, WAV, AAC, OGG, and FLAC?
Open the Audio Converter, drop in your audio file, and pick the output format you want from MP3, WAV, AAC, OGG, or FLAC. The conversion runs in your browser, then you download the new file. There is no signup, and the tool is free to use.
Is my audio file uploaded to a server when I convert it?
No. The Audio Converter runs entirely in your browser using JavaScript and WebAssembly, so your file never leaves your device or uploads to any server. The audio is processed locally on your computer, which keeps private recordings and music files in your hands only.
Can I convert a WAV file to MP3 to make it smaller?
Yes. WAV files are uncompressed and large, so converting to MP3, AAC, or OGG produces a smaller file that is easier to share or store. Choose your target format in the converter, and the file is rebuilt in that format right in your browser.
Does converting audio to a lossless format like FLAC improve the quality?
No. Converting a compressed file such as MP3 to FLAC does not add back detail that was already discarded; it only stores the same sound in a lossless container. FLAC preserves quality when you start from an uncompressed source like WAV or another lossless file.
