Converters & Time

Audio converter

Convert small audio files with lazy-loaded ffmpeg.wasm.

Lazy-load ffmpeg.wasm for small audio conversions.

Choose file

Output format

Audio limit 25MB, video limit 80MB; large files need the future cloud backend.

Formula and method

Heavy libraries lazy-load only after user action; file contents are not sent in analytics.

Example: choose a file or paste content, then download the converted result.

Are files uploaded?

V1 prioritizes local processing; disabled cloud mode is clearly labeled.

Are there size limits?

Yes, to protect mobile performance and browser stability.

Can I cancel?

Use reset/cancel to clear current state.

What if conversion fails?

Try a smaller file or another format; disabled cloud fallback will not pretend success.
