Encoder Options for PDF Files
You may specify tradeoff between quality and size for PDF files by entering the quality value to edit box or using slider. The more quality - the better image looks; the less quality - the smaller image file is.
Quality value must be within range from 0 (worst quality) to 100 (best quality).
Also, you may specify format for a page on which the image is drawn. Choose appropriate in drop down list. There are 3 variants: A4, Letter and Legal.
