Frequently asked questions
What characters get encoded into HTML entities?
Reserved and special characters such as < (<), > (>), & (&), and quotation marks are replaced with their named or numeric HTML entities. This lets you display the characters literally on a page instead of having the browser interpret them as markup.
How does encoding help prevent XSS?
By converting characters like < and > into entities, any user-supplied markup or script tags are rendered as visible text rather than executed. Encoding untrusted input before inserting it into a page is a core defense against cross-site scripting (XSS).
Can I convert entities back to normal text?
Yes. The Decode HTML Entities button reverses the process, turning entities such as & and ' back into the original & and ' characters so you can read or reuse the raw text.
What is the Swap button for?
Swap Input/Output moves your current result into the input field, which is convenient for round-tripping content, for example decoding a snippet and then re-encoding the edited version without retyping it.
Is my input sent to a server?
No. Encoding and decoding run entirely in your browser, so your text and any sensitive HTML never leave your device. The tool is free and requires no sign-up.
