The Media category at TaimurTools collects five audio and video tools. Four of them run entirely in your browser, without uploading your file anywhere. Vocal Remover splits a song into instrumental and isolated vocal tracks using the Web Audio API. Video Trimmer cuts to exact timestamps without re-encoding when possible, preserving original quality. Video to GIF converts a clip into an animated GIF with adjustable framerate, dimensions, and loop count. Video Converter transcodes between MP4, WebM, MOV, and other common formats. All four use FFmpeg.wasm for video processing, which means everything happens in your browser thanks to WebAssembly — no server roundtrip, no privacy compromise.
The trade-off for browser-only processing is speed: FFmpeg.wasm runs single-threaded by default, so encoding is roughly 0.3× to 1× real-time depending on your device and the codec. A 5-minute video typically takes 5–15 minutes to convert. For users who need server-side speed there are dozens of paid alternatives, but for one-off conversions where keeping the file private matters more than processing time, these tools cover most everyday needs. Below you will find every tool with a one-line description, then a deep-dive section for Vocal Remover.
Vocal Remover — Karaoke Maker Online
The Vocal Remover at TaimurTools splits any song into two tracks — an instrumental (no vocals) and an isolated vocal — using browser-based audio processing. You drop in an MP3 or WAV file, click Process, and after 10–30 seconds you can download both tracks separately. The tool runs entirely on your device using the Web Audio API and a JavaScript MP3 encoder; the audio file never gets uploaded to any server. This makes it suitable for songs you don't want to put on someone else's cloud, including unreleased recordings, voice memos, or copyright-sensitive material.
The separation algorithm uses a frequency-domain technique that exploits the typical mixing pattern in stereo music: vocals are usually centered (equal in both left and right channels), while instruments are often panned to specific positions. The tool computes the difference between channels to remove what's centered (the vocal) and the sum to extract it. This works extremely well on most pop and rock recordings (90%+ vocal removal) and less well on mono recordings, live recordings with heavy reverb, or songs where the vocal is not center-panned.
How to use Vocal Remover
- Open the Vocal Remover toolClick below — lamejs (the MP3 encoder) loads in the background.
- Drop your audio fileMP3, WAV, M4A, OGG accepted. Songs of any length work; processing time scales with length (typically 1× the song length).
- Click ProcessThe tool reads the audio, splits the channels, and renders two output tracks — instrumental and vocal — in your browser.
- Preview each trackTwo waveform players appear. Listen to verify the separation quality before downloading.
- Download instrumental + vocalEach track downloads as a separate MP3. WAV is also available for higher quality (larger file).
Why use this tool

Frequently asked
How clean is the vocal removal?
Quality varies by source. Modern stereo pop and rock with center-panned vocals: 90–95% vocal removal, instrumental sounds great. Older mono recordings, live concerts, or songs with heavy vocal reverb: 60–70% removal, you can still faintly hear the vocal.
Why does the instrumental sound slightly different?
The frequency-domain technique slightly alters the stereo image of the remaining instruments because we mathematically subtract the center channel. Some bass and snare drums (often center-panned in mixes) may also be reduced. This is unavoidable with this technique; commercial AI-based separation tools do this better but typically require an upload to their servers.
Can it handle a 5-minute song?
Yes. Processing time is roughly 1× the song length — so a 5-minute song processes in about 5 minutes on a fast laptop, longer on mobile.
Will the audio file be uploaded anywhere?
No. The Web Audio API processes everything locally in your browser. Verify in DevTools' Network tab that no upload requests are made.
What about copyrighted music?
Vocal removal of copyrighted material is generally fair use for personal karaoke or practice purposes in most jurisdictions, but you cannot redistribute or commercialize the resulting tracks without the original copyright holder's permission. The tool processes whatever you give it; the legal responsibility for what you do with it is yours.
Frequently asked — Media tools
Are these media tools really free?
Yes. All five media tools are free with no signup, no daily limit, and no watermark on the output. Four of them run entirely in your browser — there is no server-side encoding or rendering. The AI AV-Script Extractor is the exception: it sends your file to a free AI transcription API.
Does my video or audio file get uploaded?
No, with one exception. Vocal Remover, Video Trimmer, Video to GIF, and Video Converter use the Web Audio API and FFmpeg.wasm to process media locally, so the file binary never leaves your browser — verify in DevTools' Network tab. The AI AV-Script Extractor is the exception: transcription cannot run client-side, so it sends your file to a free AI transcription API.
What input formats are supported?
Video tools accept MP4, MOV, WebM, AVI, MKV, and most common formats handled by FFmpeg. Vocal Remover accepts MP3, WAV, M4A, OGG. Output is MP4 or WebM for video, GIF for the GIF tool, and MP3 or WAV for vocal remover.
Why is processing slow on long videos?
FFmpeg.wasm runs in a single browser thread by design, so encoding speed is roughly 0.3× to 1× real-time depending on your device. A 5-minute video typically takes 5–15 minutes to convert. For faster results, trim before converting.
Which browsers are supported?
Chrome 90+, Edge 90+, and Firefox 88+ on desktop work best. Safari 14+ works for the audio tool but has slower video processing because of WASM SIMD limitations. Mobile browsers can run all five tools but expect longer processing times.
