Tips to compress images in PDF

Select a compression rate: When compressing an image in PDF, you want to preserve the image quality to the greatest extent possible. If you are using PDFelement to do the job, you have three compression options: High, Medium, and Low to balance image quality against image size. Select the "Low" compression option, which helps your PDF images retain much image detail after considerable compression. The High compression option might result in a small loss of image quality for your PDF files.

Customize image resolution: If you want to preserve the quality of your images, you can adjust the image resolution by accessing the compression settings. Simply navigate to compress settings > image resolution, and select a quality ranging from 72dpi to 600dpi.

Reduce PDF file size by removing unnecessary information: PDFelement also provides the option to eliminate unnecessary elements like bookmarks, attachments, metadata, and comments, which can help reduce the size of your PDF image.
