Bit Depth Converter Online
Convert audio bit depth with the options that are genuinely implemented, including dither only if the encoder path applies it.
Supported formats: WAV AIFF MP3 16-bit 24-bit 32-bit Float
What this tool actually does
Four capabilities backed by the code, not by the sales deck.
Applies triangular TPDF dither only when quantising to 16-bit WAV, from the toggle in the view.
Encodes WAV, AIFF and MP3 through LAME CBR, while FLAC, AAC and OGG stay disabled because this build ships no encoder for them.
Decodes with AudioContext.decodeAudioData, encodes in local JavaScript and hands the file back as a download: no network request in the conversion path.
Real-world use cases
What people actually solve with this converter before they play live.
Prepare tracks before a DJ set.
Fix or process files without opening a full DAW.
Keep the workflow focused on the specific task instead of a general-purpose editor.
