Frequently asked questions
How do I escape string online?
Paste your text into the HTML Entity Encoder and press Ctrl/Cmd+Enter. The tool escapes &, <, >, double quotes, and apostrophes as HTML entities (&, <, >, ", ') and displays the result as plain text in your browser.
How do I escape HTML special characters online?

What is an HTML entity encoder and why use it?
An HTML entity encoder converts special characters to safe entity representations for display. Use it when embedding user-supplied text, code snippets, or markup examples into templates, CMS fields, or documentation. It ensures your content displays as text, not as executable markup.
What characters does the HTML Entity Encoder escape?
The tool encodes five core HTML special characters: & becomes &, < becomes <, > becomes >, " becomes ", and ' becomes '. These are the characters most likely to break HTML markup or be misinterpreted by parsers.
Can I escape HTML online for free without an account?
Yes. HTML Entity Encoder is free with no account required. Processing stays entirely on your device. Your input is never uploaded to DevToolMate servers and is cleared when you close the tab.
Is encoding the same as sanitization?
No. Encoding converts special characters to safe entity representations for display. Sanitization removes or filters potentially malicious tags and attributes. Use encoding when you want to show markup as text; use a full HTML filter if you need to strip untrusted code.
How do I unescape HTML entities back to characters?
Use the HTML Entity Decoder tool. It reverses the encoding process, converting &, <, >, ", and ' back to their original characters. This is useful for roundtrip verification or inspecting encoded snippets.
