URL Encoder / Decoder
Encode URLs for safe web transmission or decode encoded URLs back to readable text. Support for multiple character sets, newline separators, and live processing mode. Perfect for web developers, API integration, and URL manipulation.
How to Use the URL Encoder

Select "Encode URL" mode, enter your text, and get the URL-encoded version with proper percent encoding.
2. URL Decoding
Select "Decode URL" mode, paste an encoded URL, and get the original readable text back.
3. Character Sets
Choose from UTF-8, ASCII, ISO-8859-1, or Windows-1252 encoding for different compatibility needs.
4. Live Mode
Toggle live processing for real-time encoding/decoding or manual processing for batch operations.

Technical Information
URL encoding (also called percent encoding) is a method to encode special characters in URLs. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
This tool supports RFC 3986 URL encoding standards and handles various character sets for maximum compatibility across different systems and browsers.
The encoding process ensures that URLs remain valid and can be safely transmitted across the internet without character conflicts.
