Convert PDF to TIFF

JPedal provides several methods to allow simple conversion of a PDF file or directory of PDF files into TIFF. Java examples use the TiffEncoderOptions classes.

Convert PDF to TIFF from Command Line or another language

java -jar jpedal.jar --convert "inputFileOrDir" "outputDir" tiff

Convert PDF to TIFF in Java with convenience static method

ConvertPagesToImages.
writeAllPagesAsImagesToDir("inputFileOrDir", "output" , "tiff", 1.33f);

Convert PDF to TIFF in Java with control over the image output

ConvertPagesToImages convert = new ConvertPagesToImages("/path/file.pdf");
if (convert.openPDFFile()) {
    try {
        for (int page = 1; page <= convert.getPageCount(); page++) {
            BufferedImage bi = convert.getPageAsImage(page);
            
            File out = new File("/path/to/output/" + page + ".tiff");  
            //setters to control output (example with compression type)
            TiffEncoderOptions options = new TiffEncoderOptions();
            options.setCompressionFormat(TiffCompressionFormat.DEFLATE);
            JDeli.write(bi, options, out); 
        }
    } catch (PdfException | IOException e) {
        e.printStackTrace();
    } 
}
convert.closePDFfile();

Convert PDF to TIFF in Java with a password-protected PDF file

ConvertPagesToImages convert = new ConvertPagesToImages("/path/file.pdf");
convert.setPassword("password"); 
if (convert.openPDFFile()) {
    try {
        for (int page = 1; page <= convert.getPageCount(); page++) {
            BufferedImage bi = convert.getPageAsImage(page);
            File out = new File("/path/to/output/" + page + ".tiff");
            JDeli.write(bi, OutputFormat.TIFF, out);  
        } 
    } catch (PdfException | IOException e) { 
    		e.printStackTrace();
    } 
}
convert.closePDFfile();

If you are looking for upscaling or more complex control over the PDF to TIFF conversion, ConvertPagesToHiResImages class has lots of additional options
