Online Tools (tool.gd) is a free bilingual (Chinese/English) collection of 11153 browser-based tools across 20 categories, including unit converters, calculators, finance, math, developer, image, text and PDF tools.

How it works

Every tool runs locally in your browser. Text you enter and files you choose are not uploaded, and no sign-up is required.

Conversion factors

Unit converter pages state the factor they use (for example “1 ft = 0.3048 m”) and the formula (result = value × factor), with worked examples in the How-to & FAQ section, so results are easy to verify and cite.
