About URL Encoder/Decoder

URL encoding (also called percent-encoding) converts special characters into a format that can be safely transmitted in URLs. Characters like spaces, ampersands, and equals signs are replaced with percent-encoded equivalents (e.g., space becomes %20). This tool uses JavaScript's built-in encodeURIComponent() and encodeURI() functions.

Q: What's the difference between Encode and Encode Full URL?

Encode uses encodeURIComponent() which encodes all special characters including /, ?, and &. Encode Full URL uses encodeURI() which preserves URL structure characters, making it suitable for encoding complete URLs.

Q: When should I use URL encoding?

Use URL encoding when passing user input as query parameters, embedding special characters in URLs, or working with API requests that require percent-encoded values.

Q: Is my data sent to any server?

No. All encoding and decoding happens entirely in your browser using JavaScript. No data is transmitted to any server.
