The real app
From two files to one smooth mix in a minute
This is MixSongs itself, recorded in the browser: songs dropped on the timeline, a crossfade drawn with checkpoints, then exported. No plugins, no installer.
Try it right here
Draw a crossfade, then press play
Drag the white checkpoints to reshape how “Neon Tide” fades out under “Glass Hours”. The waveform follows the curve, so what you see is what you hear. It works the same way in the app, on as many tracks as you like.
Drag a checkpoint, or focus it with Tab and use the arrow keys. Double-click a clip to add a point; Delete removes it.
Why MixSongs
A real multitrack mixer, not another “audio joiner”
Most free tools glue files end to end with a fixed fade. MixSongs gives you a timeline, where you decide exactly how every transition sounds.
-
Volume checkpoints
Click the line to add a point, drag to shape the curve. Fades between points are linear and sample-accurate, and you can edit them while the song plays.
-
Crossfades in one drop
Add a song “in sequence” and MixSongs overlaps it with the previous one and builds the crossfade from checkpoints for you. Then fine-tune it.
-
Split, trim, duplicate
Razor tool (S), drag clip edges to trim, fade handles, copy and paste, snap to grid, beats and bars, loop regions, full undo and redo.
-
Lossless and private
A 32-bit floating-point engine runs on your device. Your songs are never uploaded to mix or export, and the project autosaves in your browser.
-
Export that respects quality
WAV 16, 24 or 32-bit float, FLAC 16 or 24-bit, or MP3 up to 320 kbps. Built-in clip protection, optional normalize and proper dither.
-
AI stems when you need them
Split a song into vocals, drums, bass and music. The four stems land as lanes in your project, each with its own fader and volume curve.
How it works
Three steps to a finished mix
- 01
Drop your songs
Drag MP3, WAV, FLAC, M4A, OGG or AIFF files onto the page. MixSongs reads each file’s real quality: bitrate, sample rate and bit depth.
- 02
Shape the transitions
Place songs at the start, at the cursor or in sequence. Draw volume checkpoints for crossfades, trim, split and loop until it flows.
- 03
Export your mix
Pick a format. MixSongs recommends the best one for your sources, renders offline and downloads the file. It never touches a server.
AI stem separation
Need just the vocals? Split any song into 4 stems.
Mel-Band RoFormer isolates the vocals, then Demucs splits the rest into drums, bass and music, on a cloud GPU in about a minute. Make a karaoke track, an acapella, or a remix-ready set of stems inside the same project.
15 separations for $2.99. One-time, no subscription.

Questions, answered
Is MixSongs really free?
Yes. Mixing, editing, crossfades and export are free with no account and no watermark. They run on your own device, so they cost us nothing. Only AI stem separation, which needs a cloud GPU, is paid: $2.99 for 15 songs.
Are my songs uploaded anywhere?
Not for mixing or exporting: decoding, playback and rendering all happen in your browser. Audio is uploaded only if you choose AI stem separation. It is deleted from our servers as soon as the stems reach your browser, and within one hour at the latest.
What file formats can I use?
You can import MP3, WAV, FLAC, M4A/AAC, OGG/Opus, WebM audio and AIFF. You can export WAV (16, 24 or 32-bit float), FLAC (16 or 24-bit) and MP3 (128 to 320 kbps).
Does it work on my computer?
MixSongs works in current versions of Chrome, Edge, Firefox and Safari on Windows, macOS, Linux and ChromeOS. A desktop or laptop is recommended for precise editing.
Can I mix songs I don’t own?
You are responsible for having the rights to the audio you use. Mixing a song for your own private listening is treated differently from publishing it. Read our Terms and Copyright policy before sharing anything you made.
Your next mix is one drag-and-drop away
