Encoding Tools

Encoding tools handle the transformation of data between different formats for safe storage, transmission, and processing. Base64 encoding is ubiquitous in web development — used in data URIs, API payloads, email attachments, JWT tokens, and inline images. Our Base64 Encoder/Decoder handles both encoding and decoding, supporting UTF-8 character sets for international text. URL encoding (percent-encoding) is essential for constructing valid URLs with special characters, query parameters, and path segments. Our URL Encoder/Decoder ensures your URLs are properly formatted according to RFC 3986. These encoding tools are indispensable when working with web APIs, constructing HTTP requests, handling binary data in text contexts, and debugging encoding issues. All encoding and decoding happens client-side, so you can safely process sensitive data like API keys or credentials without any data leaving your browser.
