URL Encoder
Paste text on the left to get URL-encoded output on the right.
What is URL Encoder?
URL Encoder is a web development tool that converts special characters and spaces in text into URL-safe encoded format using percent-encoding (also known as URL encoding). This process ensures that text can be safely transmitted in URLs without causing parsing errors or security issues.
URL encoding replaces characters that have special meanings in URLs (like spaces, ampersands, question marks) with percent-encoded equivalents. For example, a space becomes %20, and special characters like & become %26. This is essential for web applications, APIs, and any system that passes data through URLs.
This tool is crucial for developers working with web APIs, form submissions, query parameters, and any application that needs to safely transmit data through URLs while maintaining data integrity and preventing injection attacks.
What Problems Does It Solve?
URL Parsing Errors
Prevents URL parsing failures caused by special characters, spaces, and non-ASCII characters in query parameters and paths.
API Integration
Ensures safe data transmission in API requests, query strings, and REST endpoints without breaking URL structure.
Security Protection
Prevents URL injection attacks and ensures user input is safely encoded before being included in URLs.
Cross-Platform Compatibility
Ensures URLs work consistently across different browsers, servers, and platforms that may handle special characters differently.
How to Use URL Encoder
Enter Your Text
Type or paste the text you want to encode into the left panel. This can include spaces, special characters, or any text that needs URL encoding.
Click Run
Click the "Run" button to process your text. The tool will automatically encode special characters using percent-encoding.
Use Encoded Result
Copy the URL-encoded text from the right panel and use it in your URLs, API calls, or web applications safely.
URL Encoding Best Practices:
- • Always encode user input before including it in URLs to prevent injection attacks
- • Use URL encoding for query parameters, form data, and path segments
- • Common encoded characters: space (%20), & (%26), ? (%3F), # (%23), + (%2B)
- • Encode non-ASCII characters (like accented letters) using UTF-8 encoding
- • Test encoded URLs in different browsers to ensure compatibility
- • Consider using libraries like encodeURIComponent() in JavaScript for automatic encoding
