Depending on the options you choose, you can significantly alter the document's file size. These options require special attention to optimize file size and performance. When you save an Illustrator document as an AI file, consider using the following Illustrator options to optimize file size.
The Fonts option specifies when to embed the entire font not just the characters used based on how many of the font's characters are used in the document. Embedding fonts increases file size because the file contains more fonts glyphs than the document uses. The increase can be significant if, for example, you embed a font that contains 1, characters in a document that uses only 10 of those characters. Consider using the default settings to control file size.
If you choose this option, then the file size increases because you're saving two formats within the Illustrator file. Note: Because Illustrator CS includes all linked files by default, file size increases by the size of the linked files. Therefore, a file with little artwork and large linked files could significantly increase in size. When you save an Illustrator document as a PDF file, consider using the following Illustrator options to optimize file size. Choose this option if you want to be able to reopen and edit the PDF file in Illustrator.
However, this option counteracts aggressive compression and downsampling and increases the file size. The Optimize for Fast Web View option minimizes file size, facilitates page-at-a-time downloading, and replaces repeated images with pointers to the first occurrences of those images. Even if the PDF file isn't going to be viewed on the web, it's still a good idea to use the Optimize for Fast Web View option to reduce file size.
It allows users of Adobe Acrobat 6. For example, if you plan to publish a document in multiple languages, you can place the text for each language in a different layer. Your printer or prepress service provider can then show and hide the layers in Acrobat 6. Note: This option is available only when Compatibility is set to Acrobat 6. When you save an Illustrator file as a PDF file, you can compress text and line art, and compress and downsample bitmap images.
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.
Each section provides the following options for compressing and resampling color, grayscale, or monochrome images. Compression Downsampling : If you plan to use the PDF file on the web, then use downsampling to allow for higher compression. If you plan to print the PDF file at high resolution, then don't use downsampling. Deselect the option to disable all downsampling options.
Downsampling refers to decreasing the number of pixels in an image. To downsample color, grayscale, or monochrome images, choose an interpolation method, enter the desired resolution in pixels per inch. Then, enter a resolution in the For Images Above box. Illustrator downsamples all images with resolution above this threshold. Compression Compression : Determines the type of compression used. The Automatic option automatically sets the best possible compression and quality for the artwork contained in the file.
For most files, this option produces satisfactory results. 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.
ZIP compression can be lossless or lossy, depending on the Quality setting. JPEG compression is suitable for grayscale or color images. JPEG compression is lossy, which means that it removes image data and can reduce image quality. However, it attempts to reduce file size with a minimal loss of information. JPEG is the new international standard for the compression and packaging of image data.
It also provides additional advantages, such as progressive display. CCITT Consultative Committee on International Telegraphy and Telephony compression is appropriate for black-and-white images and any images scanned with an image depth of 1 bit. Group 4 is a general-purpose method that produces good compression for most monochrome images. Group 3, used by most fax machines, compresses monochrome bitmaps one row at a time. Run Length compression produces the best results for images that contain large areas of solid black or white.
Compression Image Quality : Determines the amount of compression that is applied. The available options depend on the compression method. That is, data is not removed to reduce file size, so image quality is not affected. Using 4-bit ZIP compression with 8-bit data can affect the quality, however, because data is lost. This option determines the size of the tiles for progressive display. This option results in no loss of detail or quality. Fonts option: The Subset Embedded Fonts When Percent Of Characters Used Is Less Than [x] option specifies when to embed the entire font as opposed to just the characters used in the document based on how many of the font's characters are used in the document.
For example, if a font contains 1, characters but the document only uses 10 of those characters, you could decide that embedding the font isn't worth the extra file size.

The interpolation method you choose determines how pixels are deleted: Average Downsampling averages the pixels in a sample area and replaces the entire area with the average pixel color at the specified resolution. Bicubic Downsampling uses a weighted average to determine pixel color, which usually yields better results than the simple averaging method of downsampling.
Bicubic is the slowest but most precise method, resulting in the smoothest gradations. Subsampling chooses a pixel in the center of the sample area and replaces the entire area with that pixel color. Subsampling significantly reduces the conversion time compared with downsampling, but results in images that are less smooth and continuous. Additional information. Sign in to your account.
