Step 3 – Reduce images sizes embedded in the PDF

The largest size of your PDF may be due to the images embedded in them. Therefore, reducing the images’ size can significantly reduce the PDF’s size. Here are the steps to reduce image sizes embedded in the PDF:

– Reinsert the edited image into the PDF document. Repeat the process until all images have resized according to your desired size.

– Save and compress your PDF using the method described in step one or two.

Step 4 – Make use of Save As Optimization Feature

Most PDF editors like Adobe Acrobat and Foxit have the opt-in optimization feature that you can use to compress your PDF files. These tools come with different optimization settings, including monochrome, grayscale, or color image compression. Here are the steps to compress a PDF file using Adobe Acrobat’s Save As Optimization Feature:

– Click on File > Save as other > Optimized PDF

– In the Optimization Settings pane, select which settings you would like to apply, or create your custom setting.
