🔒 Your Privacy is Guaranteed

Video Compressor uses WebAssembly (WASM) to run entirely in your browser. Open your browser's Network tab while using this tool — you'll see zero requests carrying your file data. Unlike iLovePDF and Smallpdf which upload your files to cloud servers, Dumkera processes everything locally on your device. Your data never leaves your machine. We are GDPR-compliant by design.
