What is it?
0xHEXER is a javascript based Hex-Editor that should work with every browser that supports ECMAScript 6.
For now only the core functionality is working. This means you can load a file, edit its bytes with Hex-Values or ASCII-Chracters and save it.
But be carful! At this point you cannot undo changes or return back after your browser crashes. Everything is Client-Sided.
How to use it?
Just load a file by clicking the big blue upload button on the front page. Alternatively you can drag and drop it somewhere on the front page.
After that you can edit the bytes of the file by changing the value of the Hex-Input or ASCII-Input fields.
When you are finished with editing click the settings button on the top-right corner and choose "Save File". The changed file should now saved - just like a file you download.
