Text Encoding & Decoding API

What it does

Text Encoding Tools converts text between common web-safe formats. Send plain text and choose an action, and you get the transformed string back in a structured response.

Use the URL encoder to encode or decode text, with an optional component flag for URL component handling. Use the HTML entity converter to encode or decode HTML entities. Use the binary and ASCII converter to transform text to and from binary or hex, with optional separator support when encoding or decoding binary and hex strings.

Each endpoint returns the performed action and the converted result, along with the tool name that produced it. That makes it straightforward to plug into validation flows, content pipelines, or internal utilities that need deterministic text transformations.

Text Encoding Tools fits frontend sanitisation, query-string building, template rendering, and low-level debugging where you need to inspect or normalize encoded data without guessing how it was transformed.

About this endpoint

What it does

Encodes text so it can be safely used in a URL, or decodes an encoded URL back to readable text, chosen with action. By default (component: true) reserved characters such as / ? & = are encoded too, which is what you need for a single query parameter value. Set component to false to encode a full URL while keeping its structure.

Request Body

Parameter	Type	Mandatory	Description
text	String	Yes	The input string to encode or decode.
action	ENUM	Yes	Operation to perform: `encode` or `decode`.
component	Boolean	No	When `true` (default), also encodes `/ ? & =` and other reserved characters. Set `false` to encode a full URL while keeping its structure.

Response

A successful call returns a JSON object with these fields:

Parameter	Type	Description
tool	String	Name of the tool that produced the response.
action	String	The action that was performed (echoes the request).
result	String	The URL-encoded or decoded text.

text	String	Yes	The text to convert.
action	ENUM	Yes	Conversion mode. Allowed values: `encode`, `decode`.

Response

A successful call returns a JSON object with these fields:

action	String	The action that was performed (echoes the request).
result	String	The text with HTML entities encoded or decoded.
