Simply paste your text or URL, choose whether to encode or decode it, and view the converted result immediately.

Why Use a URL Encoder / Decoder?

URLs can only contain certain characters. Spaces and special characters such as &, ?, =, %, and # must often be encoded to ensure they are interpreted correctly by browsers, servers, and web applications.

A URL Encoder / Decoder automatically converts these characters into their encoded equivalents and can also decode encoded URLs back into readable text for easier editing and debugging.

Features

• Encode URL components instantly
• Decode percent-encoded URLs
• Preserve special characters correctly
• Prepare data for query strings and web forms
• Fast browser-based processing
• Simple and easy-to-use interface
• Works on desktop, tablet, and mobile devices
• No downloads or registration required

How To Use the URL Encoder / Decoder

1. Paste a URL or text into the editor.
2. Choose Encode or Decode.
3. Click the appropriate action.
4. View the converted result instantly.
5. Copy the output for use in your application or website.

Encoding Examples

Encode a Search Query

Convert text containing spaces and special characters into a URL-safe format.

Input

hello world

Encoded Output

hello%20world

This is useful when adding search terms to a URL.

Encode URL Parameters

Special characters in query parameters should be encoded correctly.

Input

name=John & Jane

Encoded Output

name%3DJohn%20%26%20Jane

This helps prevent URLs from being interpreted incorrectly.

Decode an Encoded URL

Convert encoded characters back into readable text.

Input

https%3A%2F%2Fexample.com%2Fsearch%3Fq%3Dhello%2520world

Decoded Output

https://example.com/search?q=hello%20world

Decoding makes long URLs easier to inspect and troubleshoot.

Prepare Data for Web Forms

Many websites automatically URL-encode submitted form data.

The tool can help you:

• Verify encoded form values
• Test application inputs
• Troubleshoot submitted data
• Prepare values before sending requests

Work with APIs and Redirects

URL encoding is commonly used when sending parameters through APIs or redirecting users between web pages.

The tool makes it easy to verify that URLs are correctly encoded before they are used.

Common Uses

The URL Encoder / Decoder is useful for:

• Building query strings
• Encoding URL parameters
• Decoding encoded URLs
• API development
• Web development
• Redirect links
• Web forms
• Tracking URLs
• Debugging applications
• Testing website links

Understanding URL Encoding

URL encoding (also called percent encoding) replaces characters that aren't safe to use directly in a URL with a percent sign (%) followed by their hexadecimal value.

For example:

Character | Encoded Value

--------- | -------------

Space | %20

& | %26

? | %3F

= | %3D

| %23

Encoding ensures browsers and servers interpret URLs correctly and helps prevent errors when transmitting data.

Tips for Better Results

• Encode only the parts of a URL that require it, such as query parameters or form values.
• Decode URLs before editing them to improve readability.
• Double-check encoded URLs before using them in applications or websites.
• Keep the original URL if you need to compare the encoded and decoded versions.
• Test links after encoding to ensure they behave as expected.

Frequently Asked Questions

What does the URL Encoder / Decoder do?

It converts text into a URL-safe format and decodes percent-encoded URLs back into readable text.

What is URL encoding?

URL encoding is a standard method of replacing special characters with encoded values so they can be safely transmitted in URLs.

Why do spaces become %20?

Spaces are not valid in URLs, so they are replaced with %20, which represents a space in URL encoding.

Can I encode an entire URL?

Yes. You can encode a full URL or just individual components such as query parameters, depending on your needs.

Can I decode an encoded URL?

Yes. The tool converts encoded URLs back into a readable format, making them easier to inspect and edit.

Is my data stored?

No. Your text and URLs are processed within your browser and are not stored or shared.

Is the URL Encoder / Decoder free?

Yes. You can encode and decode URLs online for free without creating an account or downloading software.
