Joining interviews or meetings? Get them as text instead.
Transcribe to textA free MP3 joiner that runs entirely in your browser. Drop your MP3s, set the order, download one file.
Drag two or more MP3 files into the upload area, or click to browse. Files with different bitrates join fine — the output is re-encoded uniformly.
The join runs top to bottom. Reorder with the arrows until the sequence is right, and remove anything that doesn't belong.
One click merges everything into a single MP3 on your device — nothing gets uploaded — and the download is ready in seconds.
One MP3 is easier to play, share, and upload than a dozen.
Track-per-file albums and chaptered audiobooks become one continuous MP3 for any player.
Recordings captured in bursts merge into a single memo you can share in one message.
Combine intro, ad spot, and interview MP3s into an episode without an audio editor.
Stitch tracks into one long mix file — no gaps added between segments.
No problem — every input is decoded first, so 128 kbps and 320 kbps files join into one clean 192 kbps MP3.
After joining, SlayScribe can transcribe the whole MP3 into accurate, timestamped text.
MP3 plays everywhere, which is exactly why it's the format people collect in parts — and why joining it should be effortless. This tool decodes your MP3s on your device, concatenates them back to back, and re-encodes one uniform file. Your audio never touches a server.
Yes — no account, no watermarks, no limits. Everything runs in your browser.
No. Inputs are fully decoded before joining, so mixed bitrates and sample rates come out as one uniform 192 kbps MP3.

Any number under 1 GB combined — the in-browser memory ceiling.
No. The whole join happens locally on your device.
