Reduce PDF file size

You can compress bitmap images, text, and line art 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.

You can also reduce the size of a PDF file by downsampling color, grayscale, or monochrome bitmap images.

To set the bitmap compression in a PDF file

1 .	Click File Publish to PDF.

The JP2 (JPEG 2000) option is available only for Adobe Acrobat 6.0, Adobe Acrobat 8.0, and Adobe Acrobat 9.0

If you choose JPEG compression, you can specify the compression quality by moving the JPEG quality slider.

To compress text and line art in a PDF file

To downsample bitmap images in a PDF file

Downsampling color, grayscale, or monochrome bitmap images is effective only when the resolution of the bitmap image is higher than the resolution specified in the Downsampling area.
