URL Encoder / Decoder

URL encoding (also called percent encoding) converts characters that are not allowed in URLs into a format that can be safely transmitted over the Internet. Special characters are replaced with a "%" followed by two hexadecimal digits representing the character's ASCII value.

Characters that need encoding include spaces, non-ASCII characters, and reserved characters like &, ?, #, =, and many others used for URL structure.

// Original URL:
https://prettifycode.com/search?q=json%20beautifier

// URL Encoded:
https%3A%2F%2Fprettifycode.com%2Fsearch%3Fq%3Djson%20beautifier

// Special characters encoded:
Space ( ) → %20
& → %26
? → %3F
# → %23
= → %3D

URL encoding ensures that URLs work correctly across all browsers and systems, preventing broken links and parsing errors.

A URL Encoder Tool automatically converts text into URL-safe format and vice versa. It handles the complex encoding rules so you don't have to manually convert each character.

Using a URL encoder tool helps you:

• Create safe URLs with special characters and spaces
• Decode encoded URLs back to readable format
• Handle international characters and emojis in URLs
• Process multiple URLs or text lines at once
• Ensure compatibility across all browsers and systems

Whether you're building web applications, APIs, or just need to share URLs with special characters, an encoder tool saves time and prevents errors.

• Paste or type your text or URLs into the input area above
• Click "Encode" to convert special characters to URL-safe format
• Click "Decode" to convert encoded URLs back to readable text
• Enable "Process each line separately" for batch processing multiple URLs
• Copy or download the processed URLs for your projects
• Optionally, save your URL sessions locally or load previously saved data

Use "Process each line separately" when working with multiple URLs or when encoding lists of search terms. This processes each line individually, perfect for batch operations.

Always encode URLs that contain user input or special characters before using them in APIs or web applications to prevent security issues and parsing errors.
