Frequently Asked Questions

How do I know if my Base64 string is a PDF? expand_more
A Base64-encoded PDF typically starts with 'JVBERi0' which is the Base64 encoding of the PDF magic bytes '%PDF-'. The tool will show an error if the decoded data is not a valid PDF.
Should I include the 'data:application/pdf;base64,' prefix? expand_more
No. Paste only the raw Base64 string without the data URI prefix. The tool handles both formats automatically.
