Ultimate Vocal Remover, often called UVR, is a free, open-source desktop app. There is no official online version. You download it, install it, and run the models on your own computer. If you want to remove vocals without installing anything, a browser tool like our Vocal Remover does the same kind of AI separation in the cloud.
This guide explains what UVR is, when installing it makes sense, and how to get the same result in a browser.
UVR is a program for Windows, macOS and Linux. It gives you a window where you pick an input file, pick a model, and press a button. The separation runs on your machine.
The models are the part that does the work. A model is a trained AI network that has learned what a voice sounds like and what music sounds like. UVR lets you download many of them and choose one for each job.
That freedom is why people like it. It is also why it can feel hard at first. You choose the model, the settings and the output format yourself.
Most searches for "ultimate vocal remover online" come from one of these situations:
In these cases a browser tool is simply faster to start. You upload, wait about a minute, and download.
To be fair, UVR wins in some cases:
If those matter to you, install it. It is a good piece of software.
There is no model to pick. The vocal remover uses a BS Roformer model, a modern separation model that handles vocals well. If you want the voice instead of the music, the Acapella Extractor gives you the same two files with the vocal as the main result.
UVR users often run a second model to get drums or bass. In a browser you can do that in one go. Our stem splitter splits a song into six parts: vocals, drums, bass, guitar, piano and everything else. Each part can be split again, for example drums into kick, snare and cymbals.
On our test, a song that ran 4 minutes 44 seconds became six tracks in 56 seconds and cost 5 credits. Each MP3 was about 10.9 MB.
UVR is free. We are not, after the first 5 credits. Most tools cost 1 credit per minute of song, and credit packs start at $7.49 for 100 credits. That is about $0.30 for a 4-minute song. Credits are a one-time purchase and never expire.
So the honest rule is simple. For one or two songs, or when you can't install anything, a browser tool saves time. For hundreds of songs on a strong computer, UVR is hard to beat on price.

No separation is perfect, in UVR or in a browser. Dense mixes, live recordings and songs with lots of reverb leave some bleed. You may hear a faint voice in the instrumental at loud moments. Listen to both files before you use them.
No. UVR is a desktop application you download and install. Browser tools that remove vocals are separate products that run their own models in the cloud.
Yes. It is free and open source. You only pay with your own computer's time and power.
Yes. Upload the song to the Vocal Remover, press the button, and download the Instrumental and Vocals only files. You sign in with Google first, and new accounts get 5 free credits.
It depends on the song and the model. Modern models are close to each other. Try your song and listen with headphones before you decide.
