To properly change PDF size for all your document workflows, you need to have the right tools. There are several tools to change PDF size that you can download, whether you want to change PDF file size or PDF page size. Let's look at how to change the file size, page size or resolution of PDF.

How to Change PDF File Size

The PDF editor will help change PDF resolution and compress images, so the output file is significantly smaller than the original but the overall integrity of the content is maintained.

With this robust tool, you can not only change the size of PDF documents but also do a wide array of other actions, which we'll review in a bit. First, let's see the process to change PDF resolution using this versatile software.

Step 2. Change the File Size of PDF

Use the "Tools" menu option to open the "Compress" page. Here, you'll see a slider that controls the quality and resolution of the output file. If you intend to get the file at the smallest size, choose the highest compression. This will give you the lowest size possible without affecting the overall quality of the content in the PDF.

PDF files do not have a specific resolution, only raster images have a resolution. In a PDF document, text and vector graphics are rendered at the desired resolution of the output device. Therefore, there are no way to change PDF resolution after the PDF file is created.

Step 2: In the Save As PDF dialog box, click on Settings. And in the Preflight dialog, select Save as PDF/X-4 and Click OK.
