Toolora — Free Browser Tools

41 free tools in one click. JSON, JWT, Regex, PDF, image compressor, QR codes, token counter & more — 100% private, zero uploads.

Toolora is a free collection of 41 developer and productivity tools that run entirely inside your browser — no uploads, no sign-in, no tracking, no nonsense. With this extension, you can launch any Toolora tool in one click from your browser toolbar, or right-click any selected text on any webpage to instantly send it to a Toolora tool. It works everywhere, all the time, without leaving what you're doing. ──────────────────────────────────────── 🔧 WHY TOOLORA? ──────────────────────────────────────── Most online tools upload your files and text to a server. That means your passwords, your PDFs, your code, and your private data pass through someone else's machine. Toolora is different. Every single operation happens locally in your browser using JavaScript and WebAssembly. Your data never leaves your device. There is no server receiving your files. There is no database storing what you typed. This is privacy-first tooling built for people who care about where their data goes. ──────────────────────────────────────── 🛠️ TOOLS INCLUDED ──────────────────────────────────────── DEVELOPER TOOLS • JSON Formatter & Validator — Paste messy JSON, get it formatted, validated, and error-highlighted instantly.

We got tired of: • Pasting sensitive data into random online tools • Waiting for server-side processing when your browser is perfectly capable • Paying for simple utilities that should be free • Tool sites that bury the actual tool under ads and popups So we built the collection we always wanted — fast, private, and always available. If you find a bug or want to request a tool, reach out through toolora.dev. We read every message. ──────────────────────────────────────── 🌐 ALSO AVAILABLE AT TOOLORA.DEV ──────────────────────────────────────── The full Toolora toolkit is available at toolora.dev without installing anything. The extension simply makes it faster to reach tools you use every day, with the added convenience of the right-click menu and keyboard shortcut. All tools on the website work the same way — fully browser-side, no uploads, no sign-in required. ──────────────────────────────────────── Install Toolora. Use every tool, every day, with complete confidence that your data stays on your device.
