This page is part of the HexEd.it User Manual.
Analyse and edit binary files wherever you want, on any operating system, whether on a desktop or smartphone, and without installing any software. All you need is a modern web browser (Mozilla Firefox 53+, Google Chrome 58+, Opera 44+, Apple Safari 11.3+, Microsoft Edge 20+).
The complete file processing is done by your browser and HTML5 functionality. HexEd.it does not upload your data to the server.
HexEd.it has a small memory footprint - it does not keep your files in memory. This makes it possible to handle very large files even on low-RAM machines. HexEd.it has been tested on files as large as 150 GiB.
