How these are built
- Client-side only: each tool loads an open-source library (often compiled to WebAssembly) and does the actual work in your browser tab. Nothing you feed into a tool is ever sent to a server.
- Free, ad-supported: a small banner ad on each page pays for hosting. No signup, no account, no paywall, no watermarks.
- No tracking of your files: since your files never leave your device, there is nothing about them to log or sell.
