About AudioTools

AudioTools is a collection of nine free audio tools that work entirely in your web browser. It was made by Anees Ur Rehman for everyone who needs a quick audio job done — cutting a voice note, converting a file to another format, changing a voice, hearing text read aloud, speeding up a lecture, making a quiet recording louder, joining clips into one file, making a ringtone, or recording a voice — without paying for software, installing anything, or uploading private recordings to a server.

Every tool on this site runs on your own device. When you choose a file, it is read by your browser and processed locally with the Web Audio API. Nothing is uploaded to any server, nothing is stored, and nothing is shared with anyone. That is why the tools are fast even on a slow connection, and why they are safe for private recordings.

AudioTools is free forever. There is no account, no sign-up, no trial and no watermark on the files you make. The site is supported by advertising (Google AdSense) — the ads keep the tools free, and you can choose personalised or non-personalised ads with the cookie banner at the bottom of the page.

What you can do here

Audio Cutter trims any audio file to the exact seconds you want. Audio Converter changes MP3, WAV, OGG or M4A files to WAV or WebM. Voice Changer makes a voice higher, lower, faster or slower, with echo and robot effects. Text to Speech reads any text aloud in your device's voices. Audio Speed Changer speeds up or slows down any audio from 0.5× to 2×. Volume Booster makes quiet recordings louder, or normalises them to full volume. Audio Merger joins several audio files into one. Ringtone Maker cuts any audio into a ringtone with fade in and out. Audio Recorder records your voice with your microphone and downloads it.

What this site is not

AudioTools is a tools site, not a music site. There are no songs to download or stream here, and no MP3 export — MP3 encoding is not possible in a browser, and this site never claims otherwise. The tools work on your own recordings and audio files.
