A solo project. 72+ tools, free for personal use. Zero friction.
The web is full of "free online tool" sites. Most of them are barely disguised ad farms — five popups before you can use a calculator, a tracking pixel for every key you press, and a paywall to download the result. The actual utility is buried.
Loft Tools is the exact opposite. The interface is built so the tool itself is the point: load the page, get the answer, and move on. No accounts. No tracking. No friction.
Every tool runs in your browser. Format text, convert an image, hash a string — your device does the work, and the file you opened never gets uploaded anywhere. There's no server holding your data because nothing was ever sent to one.
Aggregate, cookieless analytics tell me which tools people use so I know what to keep building. Nothing in those numbers identifies you.
I'm Khine Zaw, a solo developer. I didn't build Loft Tools as a technical experiment; I built it out of pure frustration.
I was sick of the current state of utility software on the web. On one end, paid tools have become increasingly greedy — locking basic functionality behind expensive, recurring subscriptions, and often still underdelivering after you hand over your money. On the other end, the "free" alternatives have become actively hostile. They are unusable minefields of disguised download buttons, intrusive pop-ups, and aggressive trackers that follow you across the internet.
I wanted a library of everyday tools that just worked. I wanted a clean interface, instant results, and no behavioral tracking. That meant building it myself.
If a tool you need doesn't exist yet, tell me what you're looking for. The roadmap is shaped largely by what people actually need to get their work done.
Hosting hundreds of tools costs real money — but no investors, no acquisition pressure, no ruining the experience to pay the bills. Two things keep the lights on:
Sponsorships. Direct support from people and companies who use the tools and want them to keep being good.
Ads. Eventually you'll see some, but they play by rules: small, clearly marked, never animated, never the chase-you-around-the-web kind. No behavioral profiles. No selling your visit to a data broker.
That's the whole model.
