Encode or decode URL strings for safe web usage

URL Encoder / Decoder — Safely Encode Special Characters for Web URLs

  1. Paste the URL, query string, or text containing special characters into the input field. Common examples include spaces, ampersands, equal signs, and non-ASCII characters like Chinese, Japanese, or emoji.
  2. Click Encode to convert special characters into percent-encoded format (e.g., space → %20), or click Decode to reverse the process. The tool supports both encoding and decoding in both directions.
  3. Copy the encoded result and use it safely in your URLs, API requests, or web applications. Encoded URLs ensure reliable transmission across all browsers, servers, and network infrastructure.

Frequently Asked Questions

Is the URL Encoder free to use?

Yes, completely free. There are no usage limits, no account requirements, and no hidden fees. Use it as often as you need for development, debugging, or everyday web work.

Are my URLs or data uploaded anywhere?

No. All encoding and decoding is performed locally in your browser using JavaScript. Your data never leaves your device, which is especially important when working with sensitive URLs, API keys, or authentication tokens embedded in query strings.

When should I use URL encoding and what does it actually do?

URL encoding (also called percent-encoding) replaces unsafe or reserved characters with a % followed by two hexadecimal digits. Use it whenever you include special characters in URL query parameters — spaces, &, =, #, +, non-ASCII text, or any character outside the standard ASCII set. Without encoding, these characters can break URLs, cause parsing errors, or lead to security vulnerabilities. Common scenarios: passing user search queries in URLs, constructing REST API endpoints with dynamic parameters, embedding redirect URLs, and handling internationalized domain names or multilingual content.
