About TopTool
A practical collection of document, media, calculator, and color tools for recurring everyday tasks.
TopTool collects high-frequency utilities that are otherwise scattered across many single-purpose sites: document conversion, PDF work, audio and video changes, calculators, and color helpers.
The site prioritizes a short path from input to result. Tool pages explain whether work happens in the browser, which controls matter, and what the output can and cannot preserve.
