How to use it

Choose an unencrypted PDF up to 750 KB. Copy the resulting string or download it as a text file. Use Base64 to PDF to reverse the conversion.

A worked example

Every three source bytes typically become four Base64 characters. A 750,000-byte PDF produces 1,000,000 characters, excluding any optional data-URL prefix.

What to know

The output is standard padded Base64, without a data-URL prefix. Encoding increases file size and provides no privacy or encryption. The document itself is not compressed or rewritten.
