About
one299.com is a small, independent collection of free online utilities built to do one job well: solve everyday technical tasks instantly, in your browser, without sign-ups, paywalls, or clutter.
What we offer
Our tools cover the small jobs developers, writers, students, and everyday computer users run into all the time — generating a strong password, encoding and decoding Base64 or URL components, producing placeholder text, previewing Markdown, and converting times across zones. Every tool is designed to be fast, distraction-free, and usable on any device, from a desktop browser to a phone.
Privacy by design
Wherever possible, our tools run entirely in your browser. When a tool encodes text, generates a password, or converts a value, that data is processed on your own device and is not transmitted to or stored on our servers. We believe a utility you use dozens of times a day should never ask for an account or quietly collect your inputs.
How the project is funded
one299.com is free to use and supported by unobtrusive advertising. Ads let us cover hosting costs and keep building new tools without charging visitors or hiding features behind a subscription. We work to keep advertising relevant and out of the way of the actual tools.
Who builds it
one299.com is run by a single independent developer who builds and maintains every tool on the site. If you have found a bug, have an idea for a new tool, or simply want to get in touch, the Contact page tells you how to reach us — feedback genuinely shapes what we build next.
