Hexy

An online file hex-viewer with support for various binary files

Technologies: web, Typescript, React, HTML, vite

Programmers need from time to time to view binary files. There are many hex-viewers out there, but they mostly show raw data.

What is really useful for programmers is to interpret this data, to know that first 12 bytes are the header of the file, the next 4 represent the width and height in case the data is an image, and so on, endless possibilities.

That’s exactly what Hexy does.
