URL Percent-Encoding Tool

Encode special characters in URLs for safe transmission, or decode percent-encoded strings back to readable text. Choose between Component mode (encodes everything) and Full URI mode (preserves URL structure).

About this tool

URL encoding (percent-encoding) replaces unsafe characters with % followed by two hex digits. Component mode encodes all special characters, while URI mode preserves characters like :, /, and ? that are valid in URLs.
