Encoding and Decoding Tools for Base64, URL, HTML, and XML
When payloads arrive escaped, encoded, or embedded in logs, you need direct browser-side utilities that are obvious to use and safe with sensitive text. These tools focus on paste, inspect, transform, and copy workflows.
- Base64 utilities for text and PDF workflows
- Entity conversion for browser, Java, and XML strings
- Clear validation and obvious copy and download actions
