About instant.tw

instant.tw is a toolbox of 3,442 free single-page utility apps — calculators, converters, generators, trackers, and quick lookups — covering 93 categories.

Every tool is built to load fast, work in your browser without signup, and solve one problem completely. A small subset (marked freemium) has an optional paid plan for advanced use — bulk processing, history, custom branding, no ads.

The principles

• Free by default. The vast majority of tools work end-to-end with no signup.
• Fast. Static pages, no spinners, no logged-in dashboard before you can use a tool.
• Private. Tool inputs stay in your browser unless explicitly noted.
• Single-page. One tool per URL, no menus, no nesting.

Funding

instant.tw is funded by display ads (AdSense, Ezoic) on the free pages, and by Pro subscriptions on the freemium tools. Pro subscribers get ads removed across the entire site.
