About This Launch
LessMB compresses images, videos, PDFs, and ZIP files directly in the browser. Processing uses WebAssembly and WebCodecs locally, so files are not uploaded to a compression server. It is free to use and requires no account.
Why I Built This
LessMB is built around a simple idea: file compression should be fast and private without asking people to upload personal files or create an account. It brings image, video, PDF, and ZIP compression together in one free browser-based tool.
