URL Encoder/Decoder

What is URL Encoding?

URL encoding, also known as percent-encoding, is a mechanism to encode information in URLs where certain characters have special meanings or are not allowed. This process converts characters into a format that can be transmitted over the Internet safely.

Quick Reference

Encoding Types

• URL Component: Encodes all special characters except URL structure characters
• Full URI: Preserves URL structure while encoding only unsafe characters
• Custom Percent: Manual percent-encoding for complete control
