Cut Your Media In Your Browser
ZeroCutLab offers free tools that trim your audio and video files directly on your device, without ever sending them to a server. Your files always stay under your control.

Open ToolWhat Is ZeroCutLab?
ZeroCutLab is a collection of media editing tools that run entirely in your browser, with no server-side upload required. Use Audio Cutter to trim MP3, WAV, OGG and AAC files, Audio Merger to combine several audio files into one, Video Cutter to trim MP4, WebM and MOV videos in seconds, GIF Maker to turn a video clip into an animated GIF, or Image Cropper to crop and resize photos. Every tool uses Web Audio API, WebAssembly (FFmpeg), or the Canvas API to process everything directly on your device.
Why Serverless?
Traditional online media tools upload your file to a server, process it, and send it back — this creates privacy risk and long waiting times for large files. With ZeroCutLab, your file never leaves your device: your private, corporate, or personal content stays safe, and processing speed depends on your own device's power rather than your internet connection. Because there's no server cost, the tools can be offered completely free.
