ToolHive

ToolHive とは？

ToolHive is 50 free online tools — PDF/image tools, password/hash generators, JSON/YAML/SQL formatters, unit calculators, an IBAN generator, a CSS gradient builder, and more. Everything runs 100% in your browser — nothing you upload or type touches a server. No sign-up, no accounts, no file limits, no watermarks. Built this because I was tired of "free" tools that upload your files or bury the tool under ads. Open it, use it, done. Feedback welcome — actively adding tools based on requests.
