Privacy-first browser tools. Files stay on your device. Works on every platform with a modern browser.
Every tool runs in your browser. Convert an image, edit a PDF, 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.
Loft Tools is a Progressive Web App. If you have a modern browser, it works — Windows, macOS, Linux, ChromeOS, iPadOS, Android. No install required. No app store. No OS-specific build. The same 76 tools open the same way on every device.
Add it to your home screen and it acts like a native app, including offline use after the first visit.
I'm Khine Zaw, a solo developer. I built Loft Tools because I wanted a library of everyday utilities that just worked — clean interface, instant results, no signup, no tracking, no uploading my files to someone else's server.
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 76+ tools costs real money. No investors, no acquisition pressure, no quiet enshittification 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.
