Sy sammen til én MP3
Om dette værktøj
Join two or more audio files end-to-end into a single continuous track. Useful for stitching together podcast segments, voice notes recorded on a phone, music takes, lecture recordings split across multiple files, or audiobook chapters that should play as one file.
The merge runs entirely in your browser using FFmpeg-WebAssembly. All inputs are decoded and concatenated, then re-encoded once to MP3 at 192 kbps so the result plays in every player without codec surprises. Drag-and-drop to reorder before exporting and you've got a finished file in a minute.

Ofte stillede spørgsmål
No. Mix MP3, WAV, M4A and FLAC freely - everything is decoded to PCM internally and re-encoded once to MP3 for the merged output.
MP3 at 192 kbps is the safest format for universal playback (every browser, phone, car stereo and podcast app supports it). If you need a lossless merge, ZIP the originals and edit them in Audacity.
Not yet - the next version will let you set a gap in seconds between each clip. For now, prepend or append silence in the trim tool first.
Practically, the limit is your device's memory. Phones handle ~50 short clips comfortably; desktops can do hundreds.
