About clkr

clkr.work is a collection of 346 free online tools for everyday work — calculators, PDF and image tools, text utilities, developer helpers and more. Each tool lives on its own short address, like clkr.work/merge-pdf, so you can bookmark exactly what you need.

Our principles are simple:

• Free, with no signup. Every tool works without an account, trial or usage limit.
• Private by design. Tools run in your browser, so your files, text and numbers stay on your device.
• Accurate and tested. Formulas and file handling are checked against independent references before a tool goes live.
• Works everywhere. Built for phones, tablets and desktops, in light and dark mode.

Categories: Developer, Security, Text, Image, PDF, Calculators, Utility, Finance, Audio & Music, SEO, Games. New tools are added every week based on what people search for most.
