You can reduce the size of a PDF file by compressing bitmaps. Bitmap compression is available for JPEG and LZW bitmaps. Bitmaps using JPEG compression have a changeable quality scale ranging from 2 (high) to 255 (low). The higher the image quality, the larger the file size.
To compress bitmaps with LZW
1 Click File, Publish To PDF.
2 Click the Objects tab.
3 Choose LZW from the Compression Type list box.
To compress bitmaps with JPEG
1 Follow steps 1 and 2 from the previous procedure.
2 Choose JPEG from the Compression Type list box.
3 Type a number between 2 and 255 in the Quality Factor box.
• You can also specify the JPEG compression quality by moving the Quality Factor slider.
