About CrispToolHub

What is CrispToolHub?

CrispToolHub is a growing collection of free online tools that run entirely in your browser. Rather than scattering your work across a dozen ad-heavy single-purpose sites, we bring the everyday essentials — financial calculators, international tax and currency tools, a calibrated ruler, and a real compass — into one fast, clean, privacy-first hub. There is nothing to install and no account to create: open a tab and start.

Our philosophy

We build every tool around three commitments. Everything is private by default — the numbers and measurements you enter are processed locally and never uploaded or stored on a server. Everything is browser-based, so it works the same on a phone, tablet, or laptop with no download or plugin. And everything is account-free and genuinely free: no sign-up, no email, no paywall, no usage limit. The site is supported by unobtrusive advertising, which is what keeps the tools open to everyone.

Our tools

• Financial calculators — mortgage and loan payments with amortization, compound interest, SIP, SWP, inflation, ROI, salary-to-hourly, US 2025 and India 2025-26 tax, break-even, and net worth.
• International calculators — UK income tax for 2025-26, UAE and EU VAT, a Zakat calculator, a twelve-currency converter, and an international salary comparison.
• Online ruler — a true-to-life, calibrated scale in inches, centimeters, and millimeters on any screen.
• Online compass — a live heading from your phone's magnetometer, with a manual dial on laptops.

What's coming

We're just getting started. On the roadmap are a PDF toolkit for compressing, merging and converting files, an AI background remover, an AI resume and cover-letter builder, and a lightweight video editor. Each will follow the same principles as everything we've built so far — free, private, and instantly usable with no sign-up.
