About
Base64-encoded PDFs show up everywhere: API responses, email attachments, database blobs, data URIs in HTML. Paste one here to verify it is a real PDF (starts with %PDF), preview it inline, and download it as a file. The reverse direction turns any PDF into Base64 for embedding or transport.
Decoding and encoding happen entirely in your browser - confidential documents never leave your device.
