Merondis
Free calculators, converters & PDF tools — no signup
Merondis is a free, no-signup collection of 75+ online tools — calculators for finance and health, unit converters, PDF tools, developer utilities, and more. Everything runs in your browser, nothing is uploaded to a server, and there's no account required. Built as a side project to be the tool site I wished existed: fast, clean, and genuinely free.
Hey Product Hunt! 👋
I'm a database engineer by day, and I built Merondis on the side because I kept getting frustrated with calculator sites that feel cluttered, ad-heavy, or slow. I wanted something clean, fast, and genuinely free, no account walls, no upsells.
It's grown into 75+ tools across finance, health, PDF editing, developer utilities, and color tools, plus a small blog explaining the math/logic behind some of the trickier calculators (like EMI and compound interest).
Everything runs client-side in your browser, your PDFs, text, and numbers never touch a server, which was a deliberate choice for privacy and speed.
Would love your feedback, especially on what tools you'd want to see next. Thanks for checking it out!
