Base64 is a binary-to-text encoding scheme that represents binary data (like PDF files) in an ASCII string format. This is incredibly useful for transmitting documents over channels that only reliably support text.

Why Use Base64 for PDFs?

• API Data Transfer: It allows you to embed a full PDF document within a single text field in a JSON or XML payload, which is essential for many web service integrations.
• Embedding in Web Pages: You can embed a PDF directly into an HTML `<iframe>` or `<a>` tag's 'href' attribute as a data URI, enabling users to view or download a file without a separate server request.

How It Works

The PDF to Base64 converter takes a PDF file, reads its binary data, and encodes it into a Base64 data URI string. The Base64 to PDF converter reverses this process: it takes a Base64 data URI, decodes it back into its original binary data, and provides it as a downloadable PDF file. All processing is done securely in your browser.
