Is there an official UVR online?
No. Ultimate Vocal Remover is a desktop application. Its GitHub page and website offer installers for Windows 10 and later, macOS builds for Apple Silicon and Intel (Big Sur and above), and manual install steps for Linux. There is no web version from the UVR team.
Sites that call themselves "UVR online" are third parties. Some run open models such as Demucs or MDX-Net on their own servers, which is fine, but they are not made by the UVR developers. Be careful with any site that asks you to download an installer or a browser extension to "unlock" UVR: the real app is free and comes only from the official GitHub releases and website.
What UVR does well
UVR deserves its reputation. It is free and open source under the MIT licence, and it bundles several separation architectures in one app: MDX-Net, Demucs (v3 and v4), VR models and MDX23C. You can pick a model per song, chain models in an ensemble, process files in batch, and export lossless WAV. Because it runs on your own machine, nothing is uploaded anywhere.
If you have a capable computer and want the most control over models, settings and output format, UVR is the better tool. We would rather say that than pretend otherwise.
Why people look for UVR online
The usual reason is hardware. UVR's own guidance is a 64-bit system, and GPU processing needs at least an Nvidia GTX 1060 with 6 GB of memory, with 8 GB recommended. AMD support is limited to a separate DirectML build. Without a suitable GPU, UVR falls back to the CPU, which works but can take several minutes per song. Non-WAV files also need FFmpeg.
- You are on a phone, tablet or Chromebook, where UVR does not run.
- Your laptop has no Nvidia GPU, so CPU processing is slow.
- You are on a work or school computer where you cannot install apps.
- You only need one instrumental today and do not want to set anything up.
UVR desktop vs TuneSplit in the browser
| Ultimate Vocal Remover | TuneSplit | |
|---|---|---|
| Price | Free, open source (MIT) | Free for 3 files a day, then 30 credits per started 5 minutes |
| Install | Desktop app for Windows, macOS, Linux | None, runs in the browser |
| Hardware | 64-bit; Nvidia GPU with 6 GB+ for fast processing | Any device; separation runs on cloud GPUs |
| Models | MDX-Net, Demucs v3/v4, VR, MDX23C, ensembles | Demucs htdemucs |
| Stems | Depends on model, up to 4 with Demucs (6 with some models) | 2 stems or 4 stems: vocals, drums, bass, other |
| Output | WAV, FLAC or MP3, your choice | MP3 |
| Batch | Yes | One file at a time |
| Privacy | Stays on your computer | Private storage, deleted within 24 hours, never used for training |
In short: UVR wins on control, model choice and lossless output. TuneSplit wins on zero setup and working on any device.
Which one should you use?
| Your situation | Better fit |
|---|---|
| Gaming PC or Apple Silicon Mac, many songs to process | UVR desktop |
| You need WAV stems or want to compare models | UVR desktop |
| Phone, Chromebook or locked work laptop | TuneSplit |
| One or two songs and no time to set up | TuneSplit |
| You want files never to leave your machine | UVR desktop |
Getting a clean instrumental, whichever tool you use
- Start from the best source you have. A WAV or a 320 kbps MP3 separates cleaner than a low-bitrate file.
- Studio versions separate better than live recordings, where crowd noise and room reverb blur the line.
- Listen to the instrumental in headphones. Reverb tails and backing vocals are where traces usually stay.
- If a little vocal remains in a chorus, check the vocal stem for the same spot: the issue is usually a wide harmony or a delay effect.
- Use the result for practice or projects you have the rights to. Separating a song does not change who owns it.
Frequently asked questions
Is there an online version of Ultimate Vocal Remover?
No official one. UVR is a desktop app for Windows, macOS and Linux. Websites that offer "UVR online" are run by third parties using open models, not by the UVR team.
What is the best UVR alternative that works online?
TuneSplit runs Demucs htdemucs, one of the architectures included in UVR, on cloud GPUs. You get 3 free files a day, up to 10 minutes each, split into 2 or 4 stems, with MP3 download and no install.
Can I use Ultimate Vocal Remover on my phone?
No, UVR has no mobile app. On a phone you can use a browser tool such as TuneSplit, which works in Safari and Chrome.
Is TuneSplit the same quality as UVR?
TuneSplit uses Demucs htdemucs, so results are similar to choosing that model in UVR. UVR also offers MDX-Net, VR and ensembles, which can beat a single model on some songs. If you have the hardware and time to compare, UVR gives you more options.
Why is UVR so slow on my computer?
Without a supported Nvidia GPU, UVR processes on the CPU, which can take minutes per song. Its guidance is a GTX 1060 with 6 GB as the minimum and 8 GB recommended. A browser tool avoids this by running on cloud GPUs.
Can I get WAV stems?
UVR exports WAV. TuneSplit exports MP3 for uploaded songs, which is fine for practice and most projects. If you need lossless stems for mixing, UVR is the better choice.
Is TuneSplit free?
Yes, 3 files a day, up to 10 minutes each, with no sign-up. After that, each started 5 minutes costs 30 credits. There is no subscription.
Is my upload private?
Files go to private storage, are used only to make your result, and are deleted within 24 hours. They are never used for training. If you want files never to leave your computer, use UVR desktop.
