Free, privacy-first online tools
This is a growing collection of fast, dependable utilities for developers, designers, marketers and writers — image resizing, compression and conversion, JSON formatting, Base64 and JWT decoding, hashing, UUID and password generation, word counting, case and slug conversion, color palettes, QR codes, favicons, redirect rules and meta-tag previews. Each one does a single job well and loads instantly.
Why use them?
Unlike most “free online tools,” these run entirely in your browser. There is no upload step, no queue and no server round-trip, so even sensitive data — API tokens, customer files, internal text — never leaves your device. There is nothing to install and no account to create: open a tool, use it, close the tab. Each tool page also explains the format or task in depth, so you can learn the “why” as well as get the job done.
