About HTML Encoder/Decoder
Encode or decode HTML entities safely. Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
Encode data for the context where it will appear
HTML entity encoding can prevent special characters such as <, > and & from being interpreted as markup when they are meant to appear as text. Decoding reverses that representation for inspection or transformation.
Context matters. Safe handling in HTML text is not identical to safe handling inside JavaScript, CSS, URLs or attributes. Use the encoding mechanism designed for the destination context.
A realistic example
Encode a literal snippet like <strong> when you want a documentation page to display the tag characters instead of rendering bold text.
When this tool is not the right fit
Do not use generic HTML encoding as a universal defense for every injection context.
What this tool does
HTML Encoder/Decoder converts reserved HTML characters to entities and decodes HTML entities back to text.
Common use cases
- Prepare literal HTML examples
- Inspect encoded content
- Debug text escaping
Limitations
- Encoding is not sanitization for every security context.
- Always use context-appropriate escaping in production applications.
