ZIP compression can be lossless or lossy, depending on the Quality setting. ZIP compression works well on images with large areas of single colors or repeating patterns, and for black-and-white images that contain repeating patterns. Use Automatic (JPEG2000) for superior compression. Use Automatic (JPEG) if you need the greatest compatibility. For most files, this option produces satisfactory results. The Automatic option automatically sets the best possible compression and quality for the artwork contained in the file. Subsampling significantly reduces the conversion time compared with downsampling, but results in images that are less smooth and continuous.Ĭompression (Compression): Determines the type of compression used.

Subsampling chooses a pixel in the center of the sample area and replaces the entire area with that pixel color.

Bicubic is the slowest but most precise method, resulting in the smoothest gradations.

Bicubic Downsampling uses a weighted average to determine pixel color, which usually yields better results than the simple averaging method of downsampling.

Average Downsampling averages the pixels in a sample area and replaces the entire area with the average pixel color at the specified resolution.

The interpolation method you choose determines how pixels are deleted:

Illustrator downsamples all images with resolution above this threshold. Then, enter a resolution in the For Images Above box. To downsample color, grayscale, or monochrome images, choose an interpolation method, enter the desired resolution (in pixels per inch). Deselect the option to disable all downsampling options.ĭownsampling refers to decreasing the number of pixels in an image.

If you plan to print the PDF file at high resolution, then don't use downsampling. Each section provides the following options for compressing and resampling color, grayscale, or monochrome images.Ĭompression (Downsampling): If you plan to use the PDF file on the web, then use downsampling to allow for higher compression. The Compression area of the Adobe PDF Options dialog box contains three sections. Depending on the settings you choose, compression and downsampling can significantly reduce the size of a PDF file with little or no loss of detail and precision. Better learn it earlier than later.When you save an Illustrator file as a PDF file, you can compress text and line art, and compress and downsample bitmap images. You’ll hear your boss saying “I need this size for this, this size for that”, normal. Honestly, resizing is a daily work routine for every graphic designer. Some materials are horizontal and others are vertical, some are bigger, some are smaller. When I worked for an exhibition organizer, I had to resize the same design for different print materials like posters, brochures, banners, and event T-shirts. The solution is to resize the artboard area, make it smaller. Saving the logo as png or pdf when you want to print it on something is a must and certainly, you don’t want a large area of the empty background. For example, a logo is designed for use in many different presentations, on a business card, company website, T-shirt, souvenirs, etc. Adobe Illustrator is all about artboards! You can’t create a design without an artboard and often you’ll have to resize it for different purposes.
