Best free mashup makers in 2026
The short answer
To join two songs into one mix in your browser for free, use the SongUp AI Mashup Creator: upload both songs, see each one’s BPM, and and the tool stretches the second song to the first one’s tempo (key unchanged) and lines up the beats before a smooth crossfade, with a free account and unlimited WAV downloads. To put the vocals of one song over the beat of another, use SongUp AI Blend, which splits both songs into stems and matches their tempo and beats too. For fully automatic mashups from song links, try RaveDJ. For live DJ-style mixing, the free desktop apps Mixxx (DJ software) and Audacity give you full manual control.

#1 · Best for a quick two-song mashup or transition in the browser
SongUp AI Mashup Creator
Upload two songs and the tool finds each one’s tempo (BPM), stretches the second to match the first without changing its key, lines up the beats at the transition and joins them with an equal-power crossfade. Choose where the fade starts and how long it lasts, then download a WAV.

- Your songs are never uploaded
- Simple enough for a first mashup
Not so good

- Two songs at a time
#2 · Best for vocals from one song over the beat of another
SongUp AI Blend
Splits both songs into stems in your browser, then lets you choose which parts to keep from each, such as the drums and bass of one under the vocals of the other. Export the blend as WAV, or every stem as a ZIP for your DAW.

SongUp AI makes two of the tools on this list. They are first for quick, free, tempo-matched mashups in the browser; for live DJ mixing with a controller, Mixxx is the better tool.
