# ExamFo

> Free browser-based image and calculator tools for Indian students and exam applicants. Every tool runs entirely client-side in JavaScript: no file is uploaded, no account is needed, and nothing is stored on a server.

ExamFo solves two recurring problems for people filling Indian exam and government forms: getting a photo or signature to an exact file size and dimension, and doing the arithmetic that admission and eligibility rules require. All processing happens in the visitor's own browser, which means the tools work on a weak connection, impose no server-side file size cap, and never see the user's ID photo. There is no signup, no watermark and no paywall on anything.
