About ToolBurrow
ToolBurrow is a collection of small, fast, free tools for everyday file tasks — compressing an image to fit an upload limit, merging PDFs, converting formats — plus daily puzzle hint pages for word-game fans.
The site has one guiding principle: your files stay yours. Every tool runs completely inside your browser. Nothing is uploaded, nothing is stored, and the tools even work offline once the page has loaded. That makes ToolBurrow safe to use with sensitive documents like IDs, contracts and application forms.
The site is free to use and supported by advertising.
