Create a PDF of any standard by having full control over the document's image and compression options.

Color Categories

1. Color — The Color pane allows you to configure options for creating PDF documents containing color images which may be sampled for CMYK or RGB values.
• Downsampling — Configures the method used to downsample the image. Refer to the Downsampling Methods section of this guide for further details.
• Downsampling Threshold — Determines the maximum image resolution allowed before downsampling is performed.
• Convert CMYK to RGB for On-Screen Viewing — Tick this checkbox to convert images from the CMYK color-model (used for printing) to the RGB color-model (used for on-screen display).
2. Grayscale — The Grayscale pane provides configuration options for creating PDF documents which contain grayscale images. In a grayscale image, each pixel is usually stored as a byte (8 bits), which means each pixel may have a value from 0 to 255.
• Downsampling — Configures the method used to downsample the image. Refer to the Downsampling Methods section of this guide for further details.
• Downsampling Threshold — Determines the maximum image resolution allowed before downsampling is performed.
3. Mono — The Monochrome pane provides configuration options to output PDF documents which contain mono images. In a monochrome image, each pixel is usually stored as one bit, which means each pixel may have a value from 0 to 1. Monochrome images are commonly smaller in file-size than their grayscale counterparts.
• Downsampling — Configures the method used to downsample the image. Refer to the Downsampling Methods section for further details.
• Downsampling Threshold — Determines the maximum image resolution allowed before downsampling is performed.
• Compression — Configures the compression filter for monochrome images.
• CCIT (International Coordinating Committee for Telephony and Fax Encoding) — A lossless compression method that uses standard fax compression and only applies to 'black & white' images.
• Flate Encode — Uses the ZIP compression method to reduce the image size without affecting quality.
• Run Length Encode — Particularly effective on files that contain many long runs of the same bit, value, or character. This method is primarily used on binary files.
