Analyse and edit binary files wherever you want, on any operating system and without installing any software. All you need is a modern web browser (Mozilla Firefox 52+, Google Chrome 57+, Opera 44+, Apple Safari 10.1+, Microsoft Edge 20+).

The complete file processing is done by your browser and HTML5 functionality. does not send any data to the webserver. 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. has been tested on files as large as 150 GiB.

If you have any wishes for future releases, feel free to send me an email.
