HTML Entity Encode: Escape Text for HTML Online Tool
HTML Entity Encode converts text into HTML entities so reserved characters such as &, <, >, double quotes, and apostrophes can be represented safely in HTML. Choose named, decimal, or hex entities, then select whether to escape only reserved characters, all non-ASCII characters, or every non-alphanumeric character. The broader modes are useful for mixed-content text and other encoding needs.
HTML Entity Encode is an HTML entity encoder online that converts text into entity references. Use it to represent reserved HTML characters in a form that can be included in HTML, or choose a broader escaping mode when your text contains other characters you want to encode. You can select named, decimal, or hex entities for the output.
The conversion options let you control which characters are escaped. Choose reserved characters only, including &, <, >, double quotes, and apostrophes, for the focused mode. For mixed-content text, you can escape every non-ASCII character, or choose to escape every non-alphanumeric character. These settings make it possible to encode text as HTML entities according to the needs of your workflow.
HTML uses markup characters to structure content, while ordinary text may contain those same characters as data. HTML entities provide a way to represent characters within HTML rather than treating them as markup. Converting text to HTML entities can help when you need to preserve reserved characters or move content through a channel that carries HTML entities. Named entities use names, while decimal and hex entities use numeric representations.
The conversion runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. There is no signup, and once the page has loaded, the tool works offline.
This free HTML entity conversion tool is useful for developers, DevOps engineers, and anyone handling text that needs HTML escaping. Use it to encode reserved characters, prepare mixed-content text, or work with an HTML Entity value shared by someone else.
Step 1: Type or paste the text you want to encode. You can start with plain text that includes reserved HTML characters or other characters you want to represent as entities.
Step 2: Choose the HTML Entity options for the output style. The available entity styles are named, decimal, and hex.
Step 3: Select which characters to escape. You can encode only reserved characters, all non-ASCII characters, or every non-alphanumeric character.
Step 4: Review the encoded result. Check that the selected character rules match what you need for your text.
Step 5: Copy the encoded value for use in your HTML or other workflow.
Use case: Escape reserved characters before placing text in HTML. Encoding characters such as &, <, >, double quotes, and apostrophes helps represent them safely in HTML.
Use case: Prepare mixed-content text that includes non-ASCII characters. Choose the non-ASCII escaping mode when you want those characters represented as entities too.
Use case: Encode every non-alphanumeric character when a workflow needs a broader character-escaping rule than reserved characters alone.
Use case: Move text through a channel that only carries HTML entities. Convert the text to entities before sending it through that channel.
Use case: Recover the original text from an HTML Entity value someone sent you. Paste the entity input into the tool to process it.
Use case: Round-trip a value to check whether the encoding preserves the text you need. Comparing the original and processed value can help identify unexpected changes.
