Complete URL Encoding Tutorial & Guide
Master URL encoding, decoding, and analysis with step-by-step examples
URL encoding (percent encoding) converts special characters into a format safe for URLs using percent signs followed by hexadecimal codes.
// Before encoding: hello world & special chars! // After encoding: hello%20world%20%26%20special%20chars%21
Click 'Smart Detect' to automatically identify if your text is encoded or decoded. The AI will provide confidence scores and suggestions.
// Example encoded text: https%3A//example.com/search%3Fq%3Dhello%20world // AI Detection: 95% confidence - URL encoded
Use the Encode/Decode buttons or enable Auto Convert for real-time processing as you type.
// Original text: https://example.com/search?q=hello world // Encoded result: https%3A//example.com/search%3Fq%3Dhello%20world
Use the URL Analyzer to break down URL components and understand the structure of complex URLs.
// Analysis of: https://example.com/path?param=value#section // Protocol: https: // Hostname: example.com // Path: /path // Query: ?param=value // Hash: #section
Upload files or paste multiple URLs for simultaneous processing. Export results in various formats.
// Input file (URLs.txt): https://example.com/page 1 https://example.com/page 2 // Processed output with analysis and encoding
Generate ready-to-use code in your preferred programming language for easy integration into applications.
// JavaScript example:
const encoded = encodeURIComponent('hello world');
console.log(encoded); // Output: hello%20worldFrequently Asked Questions
