Add 2 to 5 MP3, WAV, M4A, AAC, OGG, FLAC, or WebM files.
Drag files to set their playback order in the merged MP3.
Matching MP3 files merge quickly. Other formats are converted locally and may take longer.

Use this free online audio joiner to combine multiple MP3 and audio files into one continuous track. Add between two and five files, drag them into playback order, and download one merged MP3. It works well for combining songs, podcast sections, interview recordings, voice memos, audiobook chapters, and separate music or narration clips.
The audio merger supports MP3, WAV, M4A, AAC, OGG, FLAC, and WebM audio. Processing happens locally with FFmpeg WebAssembly, so your recordings are not uploaded to a server, stored in the cloud, or added to a processing queue.
Choose your files or drop them onto the page. Review each filename, format, duration, and size, then drag the rows into the sequence you want. The merged track plays each complete file from beginning to end in that exact order.
When all inputs are compatible MP3 files, the tool first attempts a fast merge without re-encoding. Mixed formats or MP3 files with different codec settings are converted to a consistent 192 kbps, 44.1 kHz stereo MP3 before being joined.
This is an end-to-end audio joiner: it places one file after another. It does not overlap tracks, mix background music under speech, trim individual files, add crossfades, insert silence, or normalize loudness. If source files have noticeably different volume levels, those differences remain audible in the merged result.
Long uncompressed WAV or FLAC recordings and mixed-format projects take more memory and processing time than matching MP3 files. For very large multi-hour projects, a desktop audio editor is more reliable than browser-based processing.
Add two to five MP3 files, drag the file rows into playback order, and select Merge Audio Files. Preview the combined track and download the resulting MP3 when processing finishes.
Yes. You can mix MP3, WAV, M4A, AAC, OGG, FLAC, and WebM audio. Mixed formats are converted to matching MP3 settings before they are joined, so they take longer than compatible MP3 inputs.
Compatible MP3 streams can be joined without re-encoding. Other files are encoded as 192 kbps MP3, which provides good listening quality but is a lossy conversion. Converting a lossless WAV or FLAC source to MP3 reduces its data size and is not lossless.
No. This tool joins files end to end in the selected order. It does not overlap tracks, add crossfades, insert gaps, or normalize volume.
Short and medium projects work best. Multi-hour, high-resolution WAV or FLAC files can use substantial browser memory and take a long time to encode. For very large audiobook or recording projects, use a desktop audio editor.
No. File inspection, conversion, merging, preview generation, and download creation all happen locally in your browser. Your files never leave your device.
