How it works

Complete the job in three clear steps

  1. Add a video or audio file and choose a compatible output format.
  2. Start the local conversion and keep this tab open while it runs.
  3. Download the converted result after the browser finishes encoding it.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Questions

About this tool

Are there practical file-size limits?

Yes. Browser memory varies by device, so short and moderate-size files work best. Large or long videos may need a desktop converter.

Does Lucaden receive the media?

No. The selected file stays in browser memory. An FFmpeg WebAssembly runtime is downloaded separately when conversion starts.
