Frequently Asked Questions

What does string escaping mean?
String escaping converts special characters such as quotes, line breaks, tabs, and angle brackets into sequences that can be safely represented in a specific format.
Is JSON escaping the same as HTML escaping?
No. JSON escaping is designed for JSON string values, while HTML escaping is designed for displaying text inside HTML. Use the option that matches your target context.
Can this prevent XSS attacks?
HTML escaping can reduce risk when displaying text, but XSS prevention requires context-aware escaping, validation, and secure application design. Treat this as a utility, not a security audit.
Is my text uploaded?
No. Escape and unescape operations run locally in your browser after the page loads. Your text is not uploaded.
When should I use JSON escaping?
Use JSON escaping when text needs to become a JSON string value. It protects quotes, backslashes, line breaks, tabs, and other characters that would otherwise break the JSON string.
Why does escaping differ between formats?
Each format has its own syntax. A character that breaks HTML may be harmless in JSON, while a JSON backslash escape may not mean anything inside plain HTML.
