Free Online Audio Tools
5 browser-based audio utilities — record, trim, convert, and synthesize sound with zero uploads and zero installs.
Free online audio tools should not require installing an editor or trusting a website with your recordings. Every tool in this collection processes sound directly in your browser, so voice memos, interviews, and audio files never touch a server.
The Voice Recorder captures clean audio from your microphone with a single click — record a take, preview it instantly, and download the file. It is the fastest way to capture a voice memo, podcast intro, or pronunciation sample without opening an app.
For editing, the Audio Trimmer cuts a precise section out of any MP3, WAV, or OGG file, perfect for making ringtones, trimming silence, or isolating a quote. The Audio to WAV Converter transforms MP3, OGG, M4A, and WebM files into lossless WAV — handy when a DAW, sampler, or transcription workflow demands uncompressed input.
The Text to Speech tool reads any text aloud using your system's voices, with adjustable rate and pitch — useful for proofing your writing by ear or generating quick narration. And the Tone Generator produces sine, square, sawtooth, and triangle test tones at any frequency for testing speakers, headphones, and hearing range.
All five tools are free, need no account, and keep every byte of audio on your device.
