Free Online Tools is a small collection of browser-based utilities — a developer toolbox (JSON, Base64, regex, diff, and more), a generator hub (QR codes, passwords, UUIDs, color palettes), and an image & PDF toolbox (resize, compress, convert, merge, split).
Every tool on this site runs entirely as JavaScript inside your own browser tab. Nothing you type, paste, or upload is ever sent to a server for processing — the tools work exactly the same whether you're online or not, aside from the initial page load. That's a deliberate choice: it makes the tools faster than server-based alternatives for typical inputs, and it means you can safely use them with sensitive text, images, or documents.
The site is built and maintained by an independent developer and is supported by display advertising, which is what keeps it free to use with no account, sign-up, or usage limits. See the Privacy Policy for details on how advertising cookies work here, or the Contact page if you have feedback, a bug report, or a tool you'd like to see added.
