PNG (Portable Network Graphic) is the file format that offers lossless compression algorithm for raster images. It supports 24-bit images and offers unique transparency options – binary transparency, alpha transparency, and alpha channel. PNG format was originally designed to replace GIF, but PNG provides a much higher color depth than GIF and can be true color. The PNG images are suitable for the web, though some web browsers do not support the PNG images, in which case PNG should be converted into another graphic format like PDF. PDF is a wrapper, or container, for multiple possible types of graphic content. It can work for both bitmapped and vector images. The biggest advantage of the PDF format is that it is widely used in printing industry. It can contain multiple types of bitmapped image content at varying resolutions as well as vector art that gets printed at the resolution of the imaging hardware. So if your artwork contains any high-contrast imagery it is advisable to convert PNG images to PDF.
Converting PNG images to PDF ImageConverter Plus takes into account the individual features of each of the two image formats. One can take control of the color depth (from 1 monochrome up to 24 bit true color), compression algorithm (LZW, flate, fax) as well as a multipage layout if applicable. When converting PNG images to PDF one should bear in mind though that the converted bitmapped images in comparison to vector images will not scale up well. Vector images are more appropriate for scaling. PDF format will be able to store all the image data protecting it from being altered and keeping it device-independent.
Receive a fax and introduce some changes there
Most of us are used to a regular facsimile type – a text printed out or an image on a piece of paper. Still, lots of companies have to receive a huge number of facsimiles that have to be saved digitally, e-mailed, published on the web, added to the web catalogue and be suitable for digital editing. The main problem we face here is that fax machines usually save facsimiles in quite rare fax-type formats. More than that, some of these image formats are proprietary of a certain fax equipment which makes them different from other ones. This situation reminds the RAW format disadvantages. To make processing facsimiles more convenient you can convert them into a different image format, i.e. PDF or JPEG. As well as with the RAW files developers of ImageConverter Plus keep expanding the list of supported formats used for facsimiles. For instance, you can easily convert any number of image files saved in FXM, FXR, FXS, FXD, DEF, G3, G4 into a more suitable image format.
Convert multiple PNG images into a single PDF file via command-line of ImageConverter Plus as shown in the example below. To make things more convenient you can specify the name for the output PDF file right there in the command-line.
