What we build

Online Protractor is a browser-based angle tool made for photos, screenshots, camera views, and quick visual checks. The goal is simple: keep the measurement in context so the reading stays tied to the actual image.

Why the workflow stays visual

A number on its own is easy to misread or forget. A measured angle sitting on the original image is easier to review, compare, and share with someone else.

Privacy by design

The tool is designed to work inside your browser session, which means you can test layouts, field photos, and study material without building an account-based workflow around them.

Who it helps

Students, designers, engineers, makers, and QA teams all run into moments where a quick angle check is more useful than opening a full CAD or image-editing suite.
