MacroKit is a free, privacy-first collection of online video and image tools. Split videos into clips by duration, file size, or custom timestamps. Convert between MP4, WebM, MKV, AVI, MOV and 12+ formats. Crop and resize images with precision aspect ratio presets. Extract audio from video in MP3, WAV, FLAC, AAC, or OGG.
What makes MacroKit different: every tool runs entirely in your browser using WebAssembly and FFmpeg WASM. Your files never upload to any server — processing happens locally on your device, ensuring complete privacy. There are no watermarks, no file size limits, no daily quotas, and no account required.
MacroKit works on desktop and mobile browsers, with no software to install.
