The software can scale these images down to target a particular resolution for display or print. ![]() For example, a photograph taken by a digital camera might contain five million or more pixels, but most of this detail will not be visible unless 'zoom' controls are used. Images are often inserted into PDF files at much larger sizes than necessary. For this type of file NXPowerLite ignores the text and focuses on resizing and choosing the best format for the embedded images. PDF files generated from an electronic source - such as a Word document, a computer generated report, or spreadsheet data - will usually be formed of a combination of text and images. By reducing the resolution of these images and choosing an efficient image encoding these files can be dramatically reduced. So even documents that appear to be just text can often be entirely images. Scanners often capture document pages as high resolution images without compression. NXPowerLite is able to reduce the size of both types of PDF by resizing images, adjusting image formats and quality levels while removing background or hidden data that isn't needed for normal use of the file. It does not store any personal data.PDF files are most often scanned physical documents or documents that have been created entirely digitally often referred to as 'native' or 'born digital' PDFs.

It works great for the PDF files that are entirely made of images. Finally, clicking on the Compress button in the toolbar does the job.įree Compress PDF is a nice little tool to make PDF files smaller in file size. It depends entirely on the users how much they want to compress the images. If you reduce the quality too much, then the images won’t look so good. In the compression options, you can choose the quality of images (which is set to be 25% by default). If you have a folder containing a number of PDF files, then you can add the folder itself. If a PDF file is password protected, then you have to add that password to access the PDF file. All you have to do is click on the Add Files button to add a number of PDF files that you want to compress. The user interface of Free Compress PDF is extremely easy to follow. In addition, it can also remove some of the comments and other metadata from the PDF. The method mentioned above (compressing JPEG images) is also used by Free Compress PDF. ![]() This tool intends to reduce the size of any PDF file using a number of methods. This is the method used by a freeware tool called Free Compress PDF. When we reduce a JPEG image’s quality, its file size is also reduced. ![]() PDF file stores the images in the JPEG format and we can decrease the overall PDF filesize by reducing the quality of the JPEG images used. When we create a PDF file containing images, its size increases manifold because of all the images. Microsoft Windows itself comes with a PDF printer which adds the ability to save any file into the PDF file format. But now we can create PDF files using a number of different PDF editors as well as virtual PDF printers. In the past, it was not easy to create a new PDF file without using Adobe’s expensive software. PDF files are everywhere as they can be viewed as easily as they can be created on any platform.
