Decoding Base64 PDF Streams
APIs (like Stripe invoices, DocuSign webhooks, and AWS Lambda reports) often return generated PDF files as Base64 strings inside JSON payloads. This tool lets you inspect and download the physical PDF document without writing backend scripts.
Frequently Asked Questions
How do I convert a Base64 string to a PDF file?
Paste your Base64 encoded PDF string into the input area. The tool decodes the binary PDF stream and embeds it inside an interactive PDF viewer with a one-click 'Download .pdf File' button.
How do I know if a Base64 string is a PDF document?
Standard PDF documents in Base64 begin with 'JVBERi0x' (which corresponds to the '%PDF-1.' magic byte ASCII file header).
Is it safe to decode sensitive financial or legal PDF documents?
Yes, 100% private. All decoding runs in your browser's local sandbox memory. No invoices, tax records, or contracts are uploaded to external servers.
How do I embed a Base64 PDF in an HTML iframe?
Use '<iframe src="data:application/pdf;base64,..." width="100%" height="600px"></iframe>'.
Can I decode multi-page PDF documents?
Yes! Multi-page documents are fully rendered by the native browser PDF reader.
What should I do if my Base64 PDF fails to render?
Ensure your string includes the complete payload without truncated characters, and strip any accidental whitespace or non-Base64 characters.
