Understanding URL Encoding
URL encoding converts characters into a format that can be transmitted over the internet. Special characters like spaces, symbols, and non-ASCII characters are replaced with a percent sign (%) followed by two hexadecimal digits representing the character's ASCII code. This ensures that URLs remain valid and can be safely processed by web servers and browsers.
Privacy & Security
Your privacy is our top priority. This URL encoder/decoder operates entirely on your device using client-side processing, which means your URLs and text never leave your browser or get sent to any servers. All encoding and decoding happens locally on your computer, ensuring your data remains completely private and secure. No registration or personal information is required to use this tool.

What Is URL Encoding?
URL encoding is like translating special characters into a language that web browsers understand. Characters like spaces, symbols, and international letters can break URLs, so encoding converts them into safe formats like %20 for spaces. This ensures your URLs work correctly across all websites and applications.
Common URL Characters
- Spaces: Converted to %20 in URLs
- Symbols: Characters like & and = become %26 and %3D
- International Letters: Special encoding for accented characters
- Special Characters: Characters like #, ?, and / get encoded
- Unicode: Support for all international characters
