HTML Encoder Online - Encode Unprintable HTML Symbols

Encode your HTML replacing any unprintable symbols with character references.

The HTML Encoder is designed to assist in encoding unprintable symbols in HTML code. HTML uses a set of predefined symbols, called entities or character references, to represent special characters, such as angle brackets (< and >), quotation marks ("), ampersands (&), and others. However, there are certain symbols that cannot be directly represented in HTML code because they either have a special meaning or are considered unprintable. Examples include control characters, certain Unicode characters, or characters with specific formatting purposes. When these symbols appear in the HTML code, they need to be encoded using character references to ensure proper rendering in web browsers. The HTML Encoder Online simplifies the encoding process by automatically replacing unprintable symbols with their corresponding character references. By inputting HTML code into the tool, users can generate encoded versions of their code, making it safe for use in web pages.

Example 1: Angle Bracket Encoding

HTML Input:

String Output:

In this example, the angle brackets < and > in the original HTML code are HTML-encoded as &lt; and &gt; respectively. This encoding ensures that the angle brackets are treated as literal characters and not interpreted as HTML tags.

Example 2: Quotation Mark Encoding

HTML Input:

String Output:

Here, the quotation marks " surrounding the text are HTML-encoded as &quot;. This encoding ensures that the quotation marks are displayed correctly in the rendered HTML without causing parsing errors.

Example 3: Ampersand Encoding

HTML Input:

String Output:

In this example, the ampersand & within the URL is HTML-encoded as &amp;. The encoding is necessary because an unencoded ampersand is typically used to introduce character entities in HTML. By encoding the ampersand, the URL remains valid and does not disrupt the HTML structure.
