Jinsi Inavyofanya Kazi

Stitching audio files together normally means an upload to an ad-heavy site. This merges them with the real FFmpeg engine running in your browser.

  1. 1
    FFmpeg.wasm loads once
    The WebAssembly build of FFmpeg (~30 MB) downloads on first use and is cached afterwards.
  2. 2
    You add and order your files
    Drop in multiple audio files and arrange them with the up/down controls. Nothing is uploaded.
  3. 3
    FFmpeg concatenates them
    The tracks are joined in order — back-to-back, or with a smooth crossfade between each — using FFmpeg's concat/acrossfade filters, all on your CPU.
  4. 4
    Download the merged file
    The result is encoded once to MP3, M4A, or WAV and offered for download.

No upload, no queue, no watermark. Combine podcast segments, voice memos, or music privately — your audio never leaves your device.
