Core capabilities
- Free Audio & Voice Tools, Right in Your Browser: Private by design: Every tool processes your audio entirely in your browser. Your files are never uploaded to a server and never leave your device — nothing is stored or sent anywhere.
- Most Popular Audio & Voice Tools: Completely free: No subscriptions, no file limits, no watermarks, and no required sign-up. The site is supported by minimal ads so every tool stays free to use without limits.
- AI Text to Speech: A complete toolkit, including AI & voice: 35+ tools in one place — AI and voice tools (text-to-speech, vocal remover, voice changer, stem splitter, speech-to-text), creator effects (sped up, slowed + reverb, nightcore, bass boost, 8D audio), and editing and conversion (volume booster, audio converter, trimmer, metadata editor).
- Volume Booster: Nothing to install: All tools run in any modern web browser — no downloads, plugins, or apps. Open the page, upload your file, and process it instantly.
- Voice Changer: Works on any device: Use SoundTools on Windows, Mac, Linux, iPhone, Android, or Chromebook — anything with a modern browser, on desktop or mobile.
