URLs can only contain certain characters safely. Our URL encoder converts special characters into percent-encoded format, ensuring your URLs work reliably across all browsers, APIs, and systems without breaking due to spaces, ampersands, or other problematic characters.
🔄 Encode & decode - Bidirectional URL encoding and decoding
⚡ Instant conversion - Real-time encoding as you type
🌐 RFC compliant - Follows RFC 3986 URL encoding standards
📋 Quick copy - One-click copying of encoded URLs
🎯 Query parameter safe - Properly encode URL parameters and values
🔍 Debugging friendly - Decode URLs to understand their content
Encode Query Parameters Only
Only encode the parameter values, not the entire URL structure. Encoding 'https://' breaks URLs. Correct: https://example.com?name=John%20Doe. Incorrect: https%3A%2F%2Fexample.com.
Space Encoding Options
Spaces can be encoded as %20 or + in query strings. Use %20 for maximum compatibility. The + encoding is technically valid but can cause issues in some systems and should be avoided.
API Testing
When testing APIs with special characters in requests, encode parameter values properly to avoid 400 Bad Request errors. Ampersands, equals signs, and spaces commonly cause API issues when unencoded.
Decode for Debugging
Decode encoded URLs from logs, analytics, or browser DevTools to understand actual query parameters. This is essential when debugging issues with search queries, filters, or complex API calls.
Avoid Double Encoding
Check if data is already encoded before encoding again. Double-encoding turns %20 into %2520, breaking URLs. Always decode first, then encode, or verify encoding state before processing.
Base64 Encoder / Decoder
Encode or decode data using the Base64 scheme.
JWT Decoder
Decode and inspect JSON Web Tokens.
Data Format Converter
Convert between JSON, YAML, and XML formats with real-time validation.
JSON to Code Converter
Convert JSON objects into TypeScript interfaces, Zod schemas, or Python dataclasses.
