ABOUT WEB TOOLS

Small web tools can remove a lot of repetitive work.

Installing software just to convert one file, reduce an image, or calculate a date difference is often unnecessary. TOOLBOX is designed for quick, repeatable tasks that can be handled directly in the browser.

Convenience is only useful when the result is understandable. Each tool is paired with usage notes, cautions, FAQs, and practical guidance on processing methods, units, rounding, and other factors that can affect the outcome.
