About TeqCave
Free developer tools, built for the community.
What is TeqCave?
TeqCave is a free online toolkit for developers, designers, and power users. We provide 40+ browser-based utilities — from Base64 encoding and PDF processing to code formatters, hash generators, QR code creators, and more. Everything runs client-side where possible, meaning your data never leaves your browser.
Privacy first
Most tools process data entirely in your browser. We don't log or store what you paste or upload.
Fast and free
No paywalls, no credit card required. All 40+ tools are completely free to use, forever.
40+ tools
Base64, PDF, image conversion, formatters, JWT, DNS lookup, SSL checker, QR codes and more — all in one place.
No install needed
Works in every modern browser. No plugins, no downloads, no setup required.
Our mission
We believe developer tools should be accessible to everyone — whether you're a senior engineer at a large company or a student learning to code. TeqCave was built out of frustration with tools that require sign-ups, have usage limits, or charge for basic functionality. Our goal is to keep everything free, fast, and easy to use.
