The URL Encoder / Decoder handles the conversion between readable text and percent-encoded URL strings. This is essential when working with query parameters, API endpoints, or any URL that contains special characters like spaces, ampersands, or non-ASCII characters.

Proper Unicode handling

The tool uses JavaScript’s native encodeURIComponent() and decodeURIComponent() functions, which properly handle UTF-8 characters — an important detail that simpler implementations often get wrong. This means you can safely encode emoji, CJK characters, Arabic text, and any other Unicode content.

When you need this

Every developer working with APIs encounters percent-encoded URLs. A query parameter like q=hello world becomes q=hello%20world. Debugging API calls, constructing URLs by hand, or inspecting webhook payloads all require reliable encoding and decoding. This tool handles it instantly.
