Private by design
Files stay with you.
The actual file processing happens in your browser. A small number of advanced tools may load a browser helper library, but OutMonkey does not upload your file to do the job.

A quick check makes a better result.
OutMonkey is built to be simple enough for someone doing this once and useful enough for someone who does it every day.
What this tool is for
Button / link / icon contrast
Check small interface elements against a surface. The aim is a useful result without making you learn a full piece of software first.
Good to know
Use the number, then use your eyes.
A passing contrast result is useful, but also look at the real text size, weight, background and surrounding colours. Readability is the goal, not just the score.
If the result is for someone else, open it once as they would see it. That simple check catches a surprising number of tiny mistakes.
In plain English
You do not need to be an expert.
You do not need to be a designer to use these checks. If text feels faint or difficult to read, choose a clearer combination even when the numbers are technically acceptable.
Use contrast checks as a floor for readability, not the whole accessibility story.
