About ToolMink
ToolMink is a small, focused set of free online file converter & pdf tools — built around one idea: you should always know where your file is processed.
- 100% Free
- Most Tools Run in Your Browser
- No Signup, No Watermark
Our approach
Most ToolMink tools run entirely in your browser, which keeps your files on your device and keeps those tools fast. A few tasks — PDF to Word, OCR and Word to PDF — genuinely need a server-grade document engine, so those tools upload your file to our server, and only after you confirm it on the page. Every tool is labeled by where it processes your file before you pick one.
Most tools process files in your browser. Online processing tools send files to our server only when you start.
