Base64 to PDF Converter

Decoding Base64 Strings into Printable PDF Documents

Enterprise REST APIs, billing systems, and document generation workflows frequently transmit invoices, shipping labels, and contracts encoded as Base64 PDF strings. Verifying these documents without writing custom decode scripts can be time-consuming.

This tool decodes the raw Base64 payload back into native PDF binary data, embeds an interactive in-browser preview, and provides a direct download button so you can verify document layout, pagination, and text.

How to Use

1. Paste your Base64 PDF string (with or without `data:application/pdf;base64,` prefix) into the input box.
2. The tool strips whitespace and validates the standard `%PDF-` header magic bytes.
3. Inspect the rendered PDF document directly in the interactive viewer panel.
4. Click "Download PDF" to save the file to your hard drive.

Key Features & Capabilities

• Automatic stripping of Data URI headers, spaces, and linebreaks.
