URL / Base64 Converter

100% Client-Side

URL / Base64 Converter provides essential utilities for encoding, decoding, and converting data strings. Using native JavaScript functions like encodeURIComponent(), decodeURIComponent(), btoa(), and atob(), it transforms strings to standard URL formats or Base64 code formats without server transmission. URL encoding replaces unsafe ASCII characters with percentage notations, while Base64 translates binary or text streams into ASCII text. This tool is vital for web development, API integrations, and developer debug tasks.
