About All Tools
LivHome's tools are a free collection of browser-based utilities for everyday developer, calculation, text, time, security, and finance tasks. Most run entirely in your browser, so your input stays on your device.
The toolbox groups every utility on the site into seven categories. Developer tools cover JSON formatting, JWT decoding, SQL formatting, regex testing, UI unit conversion, a color picker, and URL encoding. The rest spans text case conversion, math converters (length, percentage, clothing sizes), time tools (converter, world clock dashboard, date and D-day calculators, timezone lookup, unit converter), crypto and security helpers (Base64, hash generator, random token generator), and finance calculators (savings, compound interest, ISA, severance pay, car tax, jeonse-to-monthly rent, and account comparison).
Pick a category that matches the job: reach for the developer tools when working with API payloads, tokens, or queries; the time tools for scheduling across zones or counting days; the crypto tools to encode data or generate hashes and tokens; and the finance calculators for savings, tax, or housing-cost estimates. The search box at the top of the hub lets you jump straight to a tool by name.
Almost every tool processes your data locally in the browser with no upload; the exception is the timezone city search and one JSON schema feature, which fetch external data. Finance results are estimates for reference only and are not professional financial, tax, or legal advice.
