Frequently Asked Questions
How do I escape JSON?
Paste your JSON into the box above and the escaped result appears instantly below. It runs entirely in your browser with nothing to upload, so you can copy or download the output right away. There is no button to press — the result updates as you type or paste.
What does escaping JSON do?
Escaping JSON replaces characters that have special meaning — like < > & and quotes — with safe equivalents, so the text can be embedded inside code, an attribute or a string without breaking it or causing injection. It is a key step when inserting user content into JSON.
Is this JSON escape tool free and private?
Yes. It is completely free with no signup, and it is private because everything happens locally in your browser — nothing is uploaded to a server. That makes it safe for sensitive snippets, and it keeps working even offline once the page has loaded.
Does it change anything besides the special characters?
No. Only the characters that need escape are touched; all your other text, spacing and line breaks are left exactly as they are. That means you can escape and reverse it again and get back precisely what you started with.
Is there a size limit?
There is no fixed limit because nothing is uploaded — the only constraint is your device’s memory, so large blocks of text process instantly. It works the same on desktop and mobile.
Does it work on every browser?
Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install, and works offline once loaded. Copy or download the result on any device.
