Reducing the size of PDF files
You can compress bitmap images to reduce the size of a PDF file. Options for bitmap image compression include JPEG, LZW, and ZIP. Bitmap images that use JPEG compression have a quality scale ranging from 2 (high quality, less compression) to 255 (lower quality, more compression). The higher the image quality, the larger the file size.
Downsampling color, grayscale, or monochrome bitmap images also reduces file size.
