Common questions about audio tools
Audio editing made simple. Record voice notes, trim clips, merge tracks, convert formats, and boost volume—all in your browser with real-time processing and zero uploads.
Audio tools are browser-based utilities for recording, editing, and converting audio files. They handle common tasks like trimming silence, merging multiple tracks, converting between formats (MP3, WAV, OGG), boosting volume, and recording directly from your microphone.
Using the Web Audio API and modern audio codecs, our tools process audio files entirely client-side. Recordings stay in your browser's memory until you download them, conversions happen using WebAssembly for speed, and editing uses audio processing graphs for precise control.
Audio files can be large and personal. Our tools keep everything local—voice memos, podcast recordings, music tracks never upload anywhere. No account required, no file size limits (within browser capabilities), and completely free forever.
