About MakeMySounds

MakeMySounds is a free collection of audio tools that run in your browser. We built it because most "free audio tools" online either plaster your screen with ads, force you to upload files to a server you don't control, or cap usage after a few tries.

Our approach is different. Whenever technically possible, your audio files never leave your device. Cutting, merging, fading, reversing, adjusting volume, shifting speed or pitch, removing silence, recording, editing ID3 tags, detecting BPM, and viewing waveforms all happen locally using the Web Audio API and client-side JavaScript. The raw audio data stays in your browser's memory from start to finish.

Some operations genuinely can't run in a browser — format conversion to FLAC, OGG, or AAC, heavy compression at specific bitrates, video-to-audio extraction, and EBU R128 loudness normalization all require server-side processing with ffmpeg. For those tools, we upload your file to our server, process it, return the result, and delete the original immediately. We're upfront about which tools use the server so you always know where your data goes.

Why "free"?

MakeMySounds is ad-supported. Ads appear below the tool interface, never on top of it, and only with your consent. We don't run ads until you opt in via the cookie banner.
