Frequently Asked Questions

What is URL Encoder Decoder?

A URL encoder decoder is a free online tool that converts text to URL-safe percent encoding and decodes percent-encoded strings back to plain text.

How do I use this URL Encoder Decoder?

Select Encode or Decode mode, type or paste your text in the input area, and the result appears instantly in the output area.

Is this URL Encoder Decoder free?

Yes, this tool is completely free to use with no signup required.

How to Use This Tool

Select mode: Encode turns plain text into percent-encoded URL-safe text; Decode reverses it.
Paste your text or URL into the input field — the conversion runs as you type.
Click "Copy Result" to put the encoded or decoded output on your clipboard. Use the swap button to reverse direction.

Common Use Cases

Building query strings: Safely embed user input, search terms, or special characters (spaces, &, =, /) into URL parameters.
Debugging API requests: Decode the URL parameters from a webhook payload, OAuth callback, or browser address bar to see the original values.
Sharing links with special characters: Encode URLs containing non-ASCII characters (e.g. Chinese, emoji) before pasting them into chat, email, or QR codes.

Frequently Asked Questions

What's the difference between encodeURI and encodeURIComponent?

This tool uses encodeURIComponent, which escapes every reserved URL character (including /, ?, &, =). Use it when encoding a value inside a query string. encodeURI leaves those reserved characters alone — use it only when encoding a whole URL.

Why is a space sometimes %20 and sometimes +?

%20 is the URL-path encoding; + is used in application/x-www-form-urlencoded query strings. This tool decodes both, but always encodes to %20 for maximum compatibility.

Will it handle non-ASCII characters like 中文 or emoji?

Yes. Characters are encoded using UTF-8 byte sequences, the standard for modern URLs. So 中 becomes %E4%B8%AD and round-trips back cleanly on decode.
