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