Reduce PDF file size
Right PDF provides various ways for you to reduce the size of PDF files. You can choose to remove unwanted data from a PDF file or shrink the images the file contains.
Using the slider bar in the Reduce File Size dialog box, you can choose a predefined size/quality ratio.
-
Open a PDF document and choose Advanced > Reduce File Size.

Reduce File Size provides five predefined ratios you can choose from to decide the most ideal outcome. If you choose to go for higher compression, you get smaller file size with less image quality, whereas you can use lower compression for higher image quality.

Level 100 (least compression, highest quality)
-
Level 75

Level 50 (the default ratio, Medium compression, medium quality)
-
Level 25
-
Level 0
