What is URL Encode/Decode?
URL Encode/Decode converts text to percent-encoded format (also called URL encoding) and decodes encoded URLs back to readable text. URL encoding replaces unsafe characters like spaces, ampersands, and non-ASCII characters with %-prefixed hex codes — essential for web development, API work, and SEO. Works entirely offline.
How to use URL Encode/Decode
1
Paste your text or encoded URL
2
Click Encode to percent-encode, or Decode to read the original text
3
Use the result in your URLs, query strings, or API calls
Common use cases
- Encoding query parameters for REST API calls
- Making URLs safe with special characters or Unicode
- Decoding messy URLs from browser address bars or logs
- Preparing URL-friendly slugs from user-generated content
Frequently Asked Questions
What's the difference between encodeURI and encodeURIComponent?
encodeURI preserves URL structure characters (:/?#[]@). encodeURIComponent encodes everything — use it for individual query parameter values. This tool defaults to full encoding for safety.
