NTN Tools curates focused utilities for people who need to get work done without navigating aggressive ads, sign-up forms, or bloated interfaces. Every calculator, converter, and generator is reviewed monthly to keep instructions current and results accurate.
Every tool documents the formulas, data sources, and rounding rules we use so you can trust the numbers.
Tasks run entirely in your browser. We do not gate features behind sign-ups or store your inputs on our servers.
Each product ships with usage guides, worked examples, and plain-language explanations for beginners.
Actively maintained products with changelog entries, roadmap visibility, and in-app guidance.

Cycle tracker that plots fertile windows, ovulation forecasts, and pregnancy test reminders.
Batch convert and compress PNG, JPG, WebP, SVG, and ICO files without uploading them to a server.

We treat every release like production software, even when it is a single-purpose calculator. Each tool ships with automated tests, manual QA checklists, and monitoring so regressions are caught before users notice.
Support is managed in-house. When you flag a bug or request a feature through our support portal, it reaches the product team that owns the tool. This keeps response times short and ensures the fix includes documentation updates.
Data privacy matters. Converters and calculators run entirely in the browser whenever possible. If a cloud service is required, we describe how data is handled and give you the option to delete it immediately.
Practical guides created by the same team that builds the tools. Use them to train teammates or to double-check your own process.
