What is everyaudiotool?

A collection of 37 free online audio tools: text to speech, transcription, vocal removal, equalizer, viral effects (nightcore, slowed + reverb, 8D), converter, trimmer, drum machine and more. Everything runs in your browser, nothing to install.

Are the tools free? Do I need an account?

Yes, they're free with no subscription. No sign-up or email needed: open the tool and use it.

Are my files uploaded to a server?

No. Audio is processed on your device with WebAssembly and Web Audio, so your files never leave your computer or phone. The only exception is YouTube to MP3, which asks our server for the video's audio track.

How do I remove vocals from a song for karaoke?

Use the Vocal Remover: upload the song and get the instrumental and vocals separately with an AI model (Demucs) that runs in your browser. To also split drums and bass, use the Stem Splitter.

How do I convert text to speech for free?

With Text to Speech: type your text, pick one of 30 Spanish or English voices, preview it and download the audio as MP3 or WAV.

How do I make a slowed + reverb or nightcore version of a song?

Upload the song to Slowed + Reverb, TikTok Slowed or Nightcore and move the speed and reverb sliders: you hear the effect in real time and download it as MP3 or WAV.

Can I transcribe audio to text or create subtitles?

Yes. Speech to Text transcribes audio in 30+ languages (or detects the language itself) with the Whisper model and lets you download the text or SRT subtitles.

Which audio and video formats are supported?

MP3, WAV, FLAC, M4A (AAC) and OGG for audio, plus MP4, MOV, AVI, MKV and WEBM to extract sound from video with Video to Audio. The converter switches between formats.

Is there a size or length limit?

Up to 100 MB and 10 minutes per file. Since everything runs in your browser, the limit depends on your device's memory; on phones, start with short files.

Does it work on mobile?

Yes, in current Android and iPhone browsers. AI tools (vocal separation, transcription) need more memory and run faster on a computer.

Can I use the audio I create in my projects?

The result is yours, but the rights to the original audio stay with its author: use your own, licensed or permitted recordings. Note that voice cloning uses a non-commercial model license and you should only clone voices with permission.
