Frequently asked questions
Is my BIN file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open a BIN file without installing software?
Drop the .bin, .dat file on this page. It opens straight away in the Hex Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my BIN file doesn't open?
Binary files always open in the hex view, so you can inspect the first bytes and search for text or signatures that reveal the real format.
