Frequently asked questions
Is String Unescape free to use?
Yes. String Unescape is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does String Unescape upload your file to a server?
No. String Unescape 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?
String Unescape 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 String Unescape?
No installation is needed. String Unescape runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use String Unescape on a phone or tablet?
Yes. The String Unescape interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. String Unescape keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
