a HTML Entity Encoderとは何ですか
An HTML Entity Encoder converts special characters to HTML entities and vice versa, preventing display issues.
使い方
Paste text to encode special characters as HTML entities, or decode entities back to text.
よくある質問
What is an HTML Entity Encoder?
An HTML Entity Encoder converts special characters into their corresponding HTML entity codes. This ensures that characters like <, >, and & are displayed correctly in web browsers rather than being interpreted as HTML code.
Why should I use this tool?
You should use this tool to prevent cross-site scripting (XSS) attacks and to ensure that user-generated content or code snippets are displayed as plain text rather than executed as HTML or JavaScript.
Which characters are encoded?
The encoder typically converts the five reserved HTML characters: the ampersand (&), double quote ("), single quote ('), less-than sign (<), and greater-than sign (>).
What is the difference between encoding and decoding?
Encoding converts plain text characters into HTML entities (e.g., < becomes <), while decoding reverses the process, converting HTML entities back into their original readable characters.
Can I encode large blocks of code?
Yes, this tool can handle large blocks of text or code. You can paste entire scripts or HTML snippets, and the tool will escape all applicable characters to make them safe for display.
Does this tool change non-ASCII characters?
It depends on the specific implementation. Some encoders only convert reserved HTML characters, while others may also convert accented characters or symbols into their numeric or named entity equivalents.
Is my data secure when using this encoder?
Yes, encoding is performed entirely within your browser. No data is sent to a server, ensuring your sensitive information remains private and secure.
