Frequently asked questions
Is XOR Encrypt/Decrypt free to use?
Yes. XOR Encrypt/Decrypt is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does XOR Encrypt/Decrypt upload your file to a server?
No. XOR Encrypt/Decrypt processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a limit on how much input I can use?
XOR Encrypt/Decrypt handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.
Do I need to install anything to use XOR Encrypt/Decrypt?

What happens to your file when I close the tab?
It is discarded. XOR Encrypt/Decrypt keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
