UtiliBox
100+ free tools, calculators, PDF utilities & health tools.
Utilibox is a free browser-based hub with 60+ tools: financial calculators (salary, loans, investments, taxes), PDF tools (compress, merge, split — all in-browser, no server upload), health calculators (BMI, ovulation, pregnancy tracking) and general utilities. Everything runs locally — your data never leaves your device.
Hey Product Hunt! 👋
I built Utilibox out of frustration — every time I needed to calculate something simple (net salary, loan payments, ovulation window, PDF compression), I'd end up on bloated sites full of ads, paywalls, or mandatory signups just to get a basic answer.
So I started building tools one by one: first a salary calculator for Brazilian labor law, then PDF utilities that run entirely in the browser (no server uploads), then health calculators, then decision-making tools like TOPSIS and PROMETHEE.
100+ tools later, the core principle is still the same: open the page, get the answer, leave. No account. No tracking. No friction.
A few things I'm proud of:
PDF tools process files locally — your documents never leave your device
Financial calculators cover Brazilian-specific rules (IRRF, INSS, 13th salary, FGTS)
Everything works on mobile without a dedicated app
Would love feedback from the PH community — especially on which tools you'd actually use or what's missing. Happy to answer any questions!
