Frequently asked questions
Are the tools on clkr.work really free?
Yes. Every tool is free to use with no signup, no account, no trial and no usage limits.
Are my files and text uploaded anywhere?
No. Images, PDFs, text and numbers are processed in your browser and are not uploaded to our servers. The one exception is Speech to Text, which uses your browser's built-in speech recognition — in some browsers (such as Chrome) that sends audio to the browser maker's speech service.
Do the tools work on phones?
Yes. Every tool is designed for mobile, tablet and desktop, and works in any modern browser without installing an app.
How do I find the right tool?
Describe what you want to do in the search box — for example 'make this photo smaller', 'combine PDF files' or 'tune my guitar' — and the best matching tool is shown first. You can also open a toolkit or browse by category: calculators, PDF, image, text, games, music, finance, developer, SEO and more.
