Free Audio Tools
in Your Browser
Professional-grade audio editing without uploading a single file. Every operation runs locally using the Web Audio API — fast, private, and free forever.
Free Online Audio Editor — No Upload, No Server
AudioTools.space is a free suite of online audio tools built for creators, podcasters, educators, and developers who need fast, private audio editing without installing desktop software. Every tool on this site runs entirely in your browser using the Web Audio API, which means your files never leave your device, processing is instant, and there is no file size limit imposed by a server.
Whether you need to trim a podcast clip, merge several voice recordings, convert an MP3 to WAV for a video project, or clean up a lecture recording by removing silence — you can do it all here, for free, in seconds.
What You Can Do with AudioTools.space
- Trim audio files online — remove unwanted intros, outros, and long pauses with visual waveform control.
- Merge audio tracks — join podcast segments, music loops, or interview clips into one seamless file.
- Convert WAV, MP3, and OGG — change formats for publishing, archiving, or cross-platform compatibility.
- Normalize audio volume — create consistent loudness across clips with peak or RMS normalization.
- Remove silence automatically — clean up spoken recordings and podcasts by cutting dead air.
