Collections
Collections gather the Toolivaro tools that belong to one real-world job into a single page — so a restaurateur, a renovator, or a developer finds every calculator they need in one place.
Restaurant business calculators Pricing, margins, and break-even math for restaurants and cafés — markups, profit margins, processing fees, and discounts in one place. Home renovation estimators Material estimates for painting, tiling, flooring, concrete, and gravel — how much to buy before you start the job. Startup and freelance finance calculators Runway, hourly rates, break-even, and compound growth — the cash math that founders and freelancers live with. Developer text and JSON toolkit Format, minify, validate, convert, and diff JSON and text — plus regex testing and token counting for LLM work. Password, hashing, and security tools Generate strong passwords, hash text with SHA-2, decode JWTs, and encode data — security utilities that run entirely in your browser. Time, date, and scheduling tools Timezone conversions, cron expressions, date differences, and meeting planning — the calendar math that schedules everything else. Format and conversion tools Convert between data sizes, number bases, color formats, and image types — quick conversions for developers and designers.
