Paste text, pick a target context (JSON, JS, HTML, SQL, regex or shell) and choose escape or unescape. The tool applies that context's escaping rules to your string.
Escaping neutralizes characters that have special meaning in a context — like quotes or backslashes — preventing broken syntax and injection bugs.
It backslash-escapes metacharacters such as . * + ? ( ) so the string matches literally instead of as a pattern.
No — always use parameterized queries. Escaping helps for display and testing but prepared statements are the real defense.
