What This Tool Does

Encode: Uses encodeURIComponent so spaces and reserved characters become percent-encoded (e.g. %20, %26)—ideal for query values and path segments.

Decode: Normalizes + to spaces, then decodeURIComponent. Invalid sequences show an error toast instead of breaking the page.

What This Tool Does

Encode: Uses encodeURIComponent for URL component-style encoding.

Decode: Normalizes plus signs to spaces, then uses decodeURIComponent for decoding.

Workflow: Paste, encode or decode, copy the result, and clear when finished.

What is URL Encoding?

URL encoding converts characters into URL-safe sequences. It is especially important for query parameters and URL components that contain spaces, symbols, Unicode characters, or reserved URL punctuation.

Why URL Encoding is Needed

Some characters have special meaning in URLs. For example, & separates query parameters, = connects keys and values, and spaces are not written literally in many URL contexts. Encoding prevents those characters from being misread.

How to Encode or Decode

  1. Paste text, a URL component, or an encoded value into the input editor.
  2. Click Encode to percent-encode it with encodeURIComponent.
  3. Click Decode to decode percent sequences; plus signs are treated as spaces first.
  4. Copy the result from the output editor.

Full URL, URL Component, and Query Parameter

This tool is best understood as a URL component encoder. Encoding an entire URL may encode structural characters such as :, /, ?, and &. For query values, that is usually correct; for a full URL, encode only the parts that need escaping.

Common Use Cases

  • Preparing query parameter values for API testing.
  • Debugging redirects and callback URLs.
  • Decoding copied URLs to inspect readable values.
  • Avoiding broken links caused by spaces or reserved characters.

Avoid Double Encoding

Double encoding happens when text that already contains encoded sequences is encoded again. For example, %20 can become %2520. If a decoded URL looks strange, check whether it has been encoded more than once.

Privacy and Processing

Encoding and decoding run in the browser using JavaScript. The tool does not submit the input to a Laravel processing endpoint.

URL Encoder & Decoder FAQ

What is URL encoding?

URL encoding converts characters into URL-safe sequences so reserved, unsafe, or non-ASCII text can be used in a web address.

What is percent encoding?

Percent encoding represents a character using a percent sign followed by hexadecimal digits, such as %20 for a space.

How do I decode a URL?

Paste the encoded text into the input area and click Decode to convert percent-encoded sequences back into readable text when valid.

Why are spaces represented differently?

In percent encoding a space is often %20. In form-style query strings, plus signs can also represent spaces, and this decoder normalizes plus signs to spaces before decoding.

What is URL component encoding?

URL component encoding is for individual pieces such as query values or path segments. It encodes characters that would otherwise have structural meaning in a full URL.

What is double encoding?

Double encoding happens when already encoded text is encoded again, turning values such as %20 into %2520 and causing confusing URLs.
