Our Base62 Encoder and Decoder is a powerful tool that converts text between regular format and Base62 encoding. It uses numbers (0-9), uppercase letters (A-Z), and lowercase letters (a-z) to create very compact, case-sensitive alphanumeric strings, making it perfect for URL shorteners and unique identifiers.

Base62 encoding is particularly useful when you need to create the shortest possible alphanumeric strings while maintaining case sensitivity. Common applications include URL shortening services, generating compact unique identifiers, and systems where maximum density is important while keeping the output URL-safe.

This tool provides real-time encoding and decoding with instant feedback, error detection for invalid Base62 input, and support for different character encodings. The interface is designed for both quick conversions and handling larger text blocks efficiently.

All processing happens locally in your browser, ensuring your data remains private and secure. No data is ever sent to external servers or stored anywhere. The tool works offline and provides instant results without any external dependencies.
