What is URL Encoding?
URL encoding (percent-encoding) converts characters into a format safe for use in URLs. Reserved and special characters—like spaces, &, =, and ?—are replaced with % followed by their two-digit hexadecimal value. This prevents URLs from breaking when they contain special characters.
How it works
- Encode: Converts text to URL-safe format using percent-encoding (e.g., space → %20, & → %26).
- Decode: Converts percent-encoded strings back to the original text.
- Use case: Essential for building query strings, passing parameters in APIs, and creating valid URLs.
Frequently Asked Questions
What is URL encoding?
URL encoding (percent-encoding) converts special characters into a format safe for use in URLs. Characters are replaced with % followed by their hexadecimal value (e.g., space becomes %20).
Is my data sent to a server?
No. All encoding and decoding happens locally in your browser. Your data is never sent to any server, ensuring complete privacy and security.
When should I use URL encoding?
Use URL encoding when building query strings, passing parameters in URLs, or including special characters (spaces, &, =, etc.) in URLs. Unencoded special characters can break URLs or be misinterpreted.
What's the difference between encodeURI and encodeURIComponent?
encodeURIComponent encodes more characters (including :, /, ?, &, =) and is used for encoding query parameter values. encodeURI preserves URL structure and is used for encoding full URLs. This tool uses encodeURIComponent for maximum compatibility.
Is this URL encoder free?
Yes, this tool is completely free to use with no sign-up or limits.
