About Base64 PDF

Base64 encoding converts binary PDF data into a text string that can be embedded in HTML, JSON, or transmitted over text-based protocols.

Encoding: upload a PDF to convert it into a data:application/pdf;base64,... string ready to use.

Decoding: paste a Base64 PDF string to preview and download the reconstructed file. Works with both raw Base64 and full data URI strings.
