URL Encode/Decode

What is URL Encoding?

URL encoding (also called percent-encoding) converts special characters into a format that can be safely transmitted in a URL. Characters like spaces, ampersands, and Unicode text are replaced with percent-encoded sequences (e.g., space becomes %20). This tool supports both component encoding and full URL encoding modes.

Common Use Cases

• Building Query Parameters — Encode values before adding them to URL query strings. Special characters like &, =, and + must be encoded to avoid breaking the URL structure.
• Debugging Encoded URLs — Decode percent-encoded URLs to read their original content. Useful when inspecting redirect chains, OAuth callbacks, or tracking parameters in analytics URLs.
• Handling International Characters — Encode non-ASCII characters (accented letters, CJK characters, emoji) for safe inclusion in URLs, form submissions, and HTTP headers.
