About MiniUtil

Small tools that finish the task

MiniUtil is a focused collection of converters, calculators, generators, and developer utilities. The goal is simple: make common one-off tasks quick without forcing an account or hiding the useful part behind a form.

What makes a tool worth publishing

A MiniUtil tool should perform the task it describes, explain important limits, work on common screen sizes, and avoid sending inputs elsewhere when the browser can do the work locally. Tools that cannot honestly provide a dependable browser-based result are replaced with practical guidance or kept out of search results until they work.

Privacy by default

Most tools process text, numbers, and files in your browser. A small number of tools need an external request to retrieve public information; those exceptions are documented in the privacy policy.

Accuracy and corrections

Calculations and conversions are checked against their stated formulas, while file and developer tools are tested with representative inputs and failure cases. Results can still be affected by browser behavior, unusual files, ambiguous standards, or mistakes. The methodology page explains the review approach and limitations.
