About the Base85 (ASCII85) Encoder & Decoder

Our Base85 Encoder and Decoder is a powerful tool that converts text between regular format and Base85 encoding. It supports both ASCII85 (used in PDF files) and Z85 (used in ZeroMQ) variants, making it versatile for different use cases. Base85 is more efficient than Base64, producing smaller output for the same input.

ASCII85 encoding is particularly useful in PDF files and PostScript documents, where it includes special features like zero compression and delimiters. Z85, on the other hand, is designed for network protocols and uses a more URL-safe character set. Both variants achieve about 25% better compression than Base64.

This tool provides real-time encoding and decoding with instant feedback, error detection for invalid Base85 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.
