URL Encode/Decode
Encode and decode URLs for safe transmission. Perfect for handling special characters in URLs and APIs.
URL Encode/Decode
Complete Guide to URL Encoding and Decoding
URL encoding is a fundamental web development technique that ensures URLs can be safely transmitted over the internet. When URLs contain special characters, spaces, or non-ASCII characters, they must be encoded to prevent parsing errors and ensure consistent behavior across different systems, browsers, and servers. Our URL encoder/decoder makes this process simple and error-free.
How to Use the URL Encode/Decode Tool
- 1
Enter URL or Text
Paste your URL, query parameters, or any text containing special characters that need to be encoded for safe URL transmission.
- 2
Choose Encode or Decode
Select whether to encode special characters into percent-encoded format (%20, %3A) or decode existing percent-encoded characters back to readable text.
- 3
Copy URL-Safe Result
Get properly encoded or decoded text that's safe for use in URLs, API calls, form submissions, and web applications.
When to Use URL Encoding
Web Development & APIs
Prepare URLs and query parameters for HTTP requests, API calls, and web service integration by properly encoding special characters.
Examples:
- • REST API query parameters
- • Form data submission
- • AJAX request URLs
- • Webhook URL construction
SEO & Marketing
Create clean, shareable URLs for marketing campaigns, tracking parameters, and SEO-friendly links with proper encoding.
Examples:
- • Campaign tracking URLs
- • Social media sharing links
- • Email marketing URLs
- • Analytics parameter encoding
Data Processing & Integration
Handle URL encoding/decoding in data pipelines, web scraping, and system integration where URLs contain dynamic content.
Examples:
- • Web scraping URL construction
- • Database URL storage
- • Configuration file URLs
- • Automated report links

How URL Encode/Decode Tool Works
This tool implements RFC 3986 compliant URL encoding (percent encoding) which converts characters to their hexadecimal representation preceded by a percent sign. The process ensures that URLs containing special characters can be safely transmitted over HTTP protocols without breaking URL parsing or causing server errors.
Compatible Platforms
- HTTP and HTTPS protocols
- REST APIs and web services
- Form submissions and query parameters
- Web browsers and HTTP clients
- Server-side applications (PHP, Python, Node.js)
- Database URL storage and retrieval
Keep in Mind
- • Does not validate URL structure or syntax
- • Cannot fix malformed URLs beyond encoding
- • Encoding entire URLs may break URL structure
- • International domain names require separate handling

URL Encode/Decode Tool - Frequently Asked Questions
What is URL encoding and why is it necessary?
URL encoding (percent encoding) converts special characters in URLs to a format that can be safely transmitted over the internet. Characters like spaces, ampersands, and non-ASCII characters are converted to percent-encoded format (like %20 for space) to prevent URL parsing errors.
Which characters need to be URL encoded?
Reserved characters like space ( ), ampersand (&), question mark (?), plus (+), percent (%), and hash (#) need encoding. Also, non-ASCII characters, control characters, and unsafe characters should be encoded for universal compatibility.
What's the difference between URL encoding and HTML encoding?
URL encoding converts characters to percent-encoded format for safe URL transmission (%20, %3A), while HTML encoding converts characters to HTML entities for safe display in web pages (<, &). They serve different purposes in web development.
Can I encode entire URLs or just query parameters?
You can encode any text, but be careful with complete URLs. Typically, you encode query parameter values and path segments individually, not the entire URL structure (protocol, domain, etc.), as this would break the URL format.
