Upload a file, drag the start and end markers on the waveform (or type the time in seconds) and click "Build & download". The MP3 or WAV is built right in your browser and downloads instantly — no sign-up, no software.
Can I join several pieces into one track?
Yes. Add several files — each becomes a clip in the list. Reorder, duplicate and trim each one; on build all pieces are joined into a single file in order.
Is it free and private? Are files uploaded?
Fully free, no limits, no watermarks. Nothing is uploaded — trimming and joining run locally in your browser, the audio never leaves your device.
Which formats are supported?
Input: mp3, wav, m4a, ogg (flac in some browsers). Output: MP3 (128, 192 or 320 kbps) or 16-bit WAV. Fade-in and fade-out included.
