PDF File Encoding to Base64

See more Base64 Examples

Demonstrates how to encode a PDF file to base64, and then decode. C#

bool success = false;

Chilkat.BinData pdfData = new Chilkat.BinData();

success = pdfData.LoadFile("qa_data/helloWorld.pdf");
if (success != true) {
    Debug.WriteLine("failed to load PDF file.");
    return;
}

// Encode the PDF to base64
// Note: to produce base64 on multiple lines (as it would appear in the MIME of an email),
// pass the string "base64_mime" instead of "base64".
string b64 = pdfData.GetEncoded("base64");
Debug.WriteLine(b64);

// Decode from base64 PDF.
Chilkat.BinData pdfData2 = new Chilkat.BinData();
pdfData2.AppendEncoded(b64,"base64");
success = pdfData2.WriteFile("qa_output/helloWorld2.pdf");
if (success != true) {
    Debug.WriteLine("failed to write PDF file.");
    return;
}
