Compress Video Locally Without Internet Upload

Compress videos locally in browser without server upload. Complete privacy and security of your files.

Privacy is important, especially when working with personal or work video materials. Many online services upload your videos to their servers for processing, which creates risks of data leakage. VideoTools.online works differently - all calculations are performed locally in your browser using WebAssembly technology and ffmpeg.wasm. Videos never leave your device, ensuring maximum security and privacy. At the same time, you get the full functionality of professional video compression programs.
