PDF Compressor

Advanced users interested in converting images to PDF documents as well as controlling each aspect of this operation can turn to PDF Compressor, a command-line tool that supports a vast range of settings.Installing the console-based application isn't required since you can just run the launcher from the downloaded package. Using the -help command generates a pretty long list of options provided by this utility.

Convert images to PDFs and vice versa

The syntax is img2pdf [options] <Image-file> [<PDF-file>], meaning that it comes down to the source picture file, target PDF, and settings. Batch processing isn't available, so it can operate on one document at once.If you're attempting to convert JBIG2 or JPEG200 files, you can instruct PDF Compressor to apply lossless compression (-lossless). It's also possible to specify the compression method for colored images (0 for no change, 1 for JPEG arithmetic, 2 for JPEG2000 arithmetic) and for black and white photos (0 for no change, 1 for CCITT G4 arithmetic, 2 for JPEG2 arithmetic).

Configure a wide range of settings

The reversal operation is possible so you can turn PDF documents into images with the help of this program. You can set the page range if you don't wish to use all of them (-firstpg, -lastpg), set the DPI (-iswh), color depth manually or automatically(-bitcount, -autobitcount) and DPI resolution (-pidpi).Furthermore, PDF Compressor can create multipage TIFFs (-multipage), rotate pages (-rotate <angle>), open the PDF file right after it's created (-view), set PDF metadata (-producer, -creator, -subject, -author, -keywords), encrypt the file (-encryption), merge two PDFs into a single one (-mergepdf), and so on. Examples are displayed.Operations were carried out fast in our tests while the tool remained light on system resources usage. Too bad that it hasn't received updates for a long time. Otherwise, PDF Compressor offers comprehensive options for those interested in image-to-PDF conversion using the console.
