Merge audio files online
Join several audio files into one, right in your browser, without uploading anything. Pick MP3, WAV, OGG, M4A or FLAC files — or video files, whose audio tracks are merged and whose pictures are dropped — arrange them in the order you want, and save the joined recording in the format you choose. The tool is built for short clips: merging happens on your device, so long recordings can take a while.

Merging audio, simply explained
The tool reads each file on your device and joins them end to end, in the order shown, into one continuous recording — always a fresh encode, never a copy of the old sound into a new container, so files recorded at different sample rates or channel counts still join cleanly. No silence is added between the parts: each part starts where the previous one ends. Only the first audio track of each file is kept: a video file merges from its audio track alone, its picture dropped, and a file with no audio track is refused. MP3 plays almost everywhere and its bitrate is yours to pick; WAV is uncompressed and larger; OGG carries Opus sound and accepts mono sound only; M4A carries AAC sound; FLAC is lossless and compressed, so it keeps every detail without the size of a WAV. Everything runs on your device, which keeps your files private but means speed depends on your device — short clips finish quickly, while long recordings can take a very long time, so this tool is best for short clips.
Private by design.
