Base64 to PDF: frequently asked questions
How do I convert Base64 to PDF?
Paste the Base64 string and press Convert to PDF. Preview the document and download it.
Can I paste a data URI?
Yes. Strings starting with data:application/pdf;base64, work, as do strings with line breaks or URL-safe characters.
Why does it say the result is not a PDF?
The Base64 decoded correctly but the data is not a PDF file. It may be an image or other file; try the Base64 to Image tool.
