Online Vocal Remover is a browser-based tool that separates an uploaded audio file into vocal and instrumental tracks. Users can preview both stems before deciding what to download. It accepts MP3, WAV, M4A, and OGG files up to 50 MB. Processing and preview are available before download; downloading requires sign-in. Separation quality depends on the source mix: reverb, backing vocals, dense arrangements, and overlapping frequencies can leave artifacts or affect instruments. I am the developer of the product. Please only process audio you own or have permission to use.
