About OhMyTools
A free, bilingual collection of browser tools that respect your privacy.
What is OhMyTools?
OhMyTools is a free collection of 251 online tools — calculators, converters, formatters and developer utilities — available in English and Chinese.
Every tool runs directly in your browser. All processing happens client-side, so the data you type into a tool stays on your device and is never sent to a server.
Why we built it
Most online tools are buried under ads, sign-ups and clutter. OhMyTools keeps things simple: open a tool, get the answer, move on. No installation, no account, no waiting.
