URL Encode/Decode Tool
This URL Encode/Decode tool helps you convert text to URL-encoded format and vice versa. URL encoding replaces unsafe ASCII characters with a “%” followed by two hexadecimal digits, ensuring URLs are properly formatted for web transmission.
How to use: Enter your text in the input box, select the operation you want to perform, and click the corresponding button. The tool also parses URLs into their components for better understanding of URL structure.

About URL Encoding
URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. URL encoding is used when placing text in a query string to convert characters that are not allowed in URLs to a format that is.
Why URL Encoding is Necessary
- Special characters: URLs can only contain a specific set of ASCII characters. URL encoding ensures all characters can be transmitted safely.
- Reserved characters: Some characters have special meanings in URLs (like ? and &) and must be encoded when used as part of the data.
- Non-ASCII characters: Characters outside the ASCII set (like accented letters or symbols) need to be encoded for proper transmission.
encodeURI vs. encodeURIComponent
JavaScript provides two different functions for URL encoding:
- encodeURI(): Encodes a complete URI, but does not encode characters that have special meaning in a URL (like /, ?, :, @, &, =, +, $, and #).
- encodeURIComponent(): Encodes all characters that could have special meaning, making it suitable for encoding parts of a URL like query parameters.
This tool provides both options, allowing you to choose the appropriate encoding method for your specific needs.
URL Encode/Decode Tool | Encode URLs Online
Encode and decode URLs instantly. Our free URL encoder/decoder handles special characters, spaces, and non-ASCII text for web development and SEO.
Introduction
Ever encountered a URL filled with strange % symbols and numbers? Or tried to share a link that broke because it contained spaces or special characters? URLs have strict rules about which characters they can contain. A URL encode/decode tool solves these problems by properly formatting web addresses. This guide will explain URL encoding and show how our free tool ensures your links work correctly every time.
What is a URL Encode/Decode Tool?
A URL encode/decode tool converts text into a URL-safe format and vice versa. Encoding replaces unsafe characters with % followed by hexadecimal codes, while decoding reverses this process.
Our versatile tool handles:
- URL encoding (percent-encoding)
- URL decoding (reverting to original text)
- Full URLs or individual components
- Multiple character sets and languages
- Batch processing of multiple strings
Why URL Encoding is Essential
Proper URL encoding prevents errors and ensures reliable web functionality across all platforms.
1. Web Development
Web applications use encoded URLs to safely transmit data in query strings and form submissions.
2. SEO and Link Building
Properly encoded URLs improve search engine crawling and prevent broken links in your content.
3. API Development
APIs require encoded parameters to handle special characters and non-English text correctly.
4. Data Transmission
Encoding ensures special characters don’t interfere with HTTP protocol during data transfer.
Common Characters That Require Encoding
Some characters always need encoding in URLs because they have special meanings.
Reserved Characters
- & (ampersand) – separates parameters
- = (equals) – assigns values
- ? (question mark) – starts query string(hash) – indicates page fragment
- Unsafe Characters
- Spaces – become %20 or +
- < > (angle brackets) – can break HTML
- ” (quotes) – cause parsing issues
- % (percent) – already used in encoding

URL Encoding Best Practices
Follow these guidelines for proper URL handling in your projects.
Encode Complete Components
Encode each URL component (path, query parameters) separately rather than the entire URL at once.
Use UTF-8 Encoding
Always specify UTF-8 character encoding to properly handle international characters.
Encode Spaces as %20
While + is accepted for spaces, %20 is the standard and more reliable across systems.
Test Encoded URLs
Always verify encoded URLs work correctly in browsers before deployment.
Conclusion
URL encoding is a fundamental web technology that ensures links work reliably across all platforms and browsers. A reliable URL encode/decode tool eliminates the guesswork from handling special characters, spaces, and international text in web addresses. Whether you’re a developer building applications, a marketer creating shareable links, or a user troubleshooting broken URLs, proper encoding ensures your web addresses work as intended.
