URL Encoder/Decoder

Encode and decode URLs for web development

What Is a URL Encoder?

A URL encoder converts unsafe or special characters into a format that can be safely transmitted over the internet. These characters are replaced with a percent sign (%) followed by two hexadecimal digits, ensuring the URL works properly in browsers and query strings.

Why URL Encoding Is Important

Example:

  • Prevents broken links
  • Ensures correct data transmission
  • Avoids browser and server errors

What Is a URL Decoder?

A URL decoder does the opposite of encoding. It converts percent-encoded characters back into normal, readable text, making URLs easy to understand and debug.
