Everything happens 100% locally in your browser, so your files never leave your device. No upload delays, no privacy worries, and no storage limits. Just quick, accurate conversions for documents, images, spreadsheets, and presentations.

Purpose

We built CyberBrox because every free converter I tried either had popups, slowed me down with uploads, or made me sign up just to download my file. It felt like a waste of time and a privacy risk.

Modern browsers support powerful code via WebAssembly (WASM), so I created CyberBrox as a lightweight, private, and always-free converter that runs entirely in your browser no installs, no data mining, just straight-up conversion.
