Choose the right graphics format

InDesign can import a wide range of graphics file formats. Consult with the service providers who will help you produce your document to clarify which formats to use. You can then plan your document around those formats and the options that best apply to your project.

The following table summarizes what graphics formats would work best for the kind of document you’re designing.

About vector graphics

Vector graphics (sometimes called vector shapes or vector objects) are made up of lines and curves defined by mathematical objects called vectors, which describe an image according to its geometric characteristics.

You can freely move or modify vector graphics without losing detail or clarity, because they are resolution-independent—they maintain crisp edges when resized, printed to a PostScript printer, saved in a PDF file, or imported into a vector-based graphics application. As a result, vector graphics are the best choice for artwork, such as logos, that will be used at various sizes and in various output media.

The vector objects you create using the drawing and shape tools in Adobe Creative Suite are examples of vector graphics. You can use the Copy and Paste commands to duplicate vector graphics betweenCreative Suite components.

About bitmap images

Bitmap images—technically called raster images—use a rectangular grid of picture elements (pixels) to represent images. Each pixel is assigned a specific location and color value. When working with bitmap images, you edit pixels rather than objects or shapes. Bitmap images are the most common electronic medium for continuous-tone images, such as photographs or digital paintings, because they can more efficiently represent subtle gradations of shades and color.

Bitmap images are resolution-dependent—that is, they contain a fixed number of pixels. As a result, they can lose detail and appear jagged if they are scaled to high magnifications on‑screen or if they are printed at a lower resolution than they were created for.

Bitmap images sometimes require large amounts of storage space, and often need to be compressed to keep file sizes down when used in certain Creative Suite components. For instance, you compress an image file in its original application before you import it into a layout.


In Adobe Illustrator, you can create bitmap effects in your artwork using effects and graphic styles.

Image resolution guidelines for final output

Bitmap images contain a fixed number of pixels, usually measured in pixels per inch (ppi). An image with a high resolution contains more, and therefore smaller, pixels than an image of the same printed dimensions with a low resolution. For example, a 1‑inch‑by‑1‑inch image with a resolution of 72 ppi contains a total of 5184 pixels (72 pixels wide x 72 pixels high = 5184). The same 1‑inch‑by‑1‑inch image with a resolution of 300 ppi would contain a total of 90,000 pixels.

For imported bitmap images, image resolution is determined by the source file. For bitmap effects, you can specify a custom resolution. To determine the image resolution to use, consider the medium of final distribution for the image. The following guidelines can help you determine your requirements for image resolution:

Commercial printing

Commercial printing requires 150 to 300 ppi (or more) images, depending on the press (dpi) and screen frequency (lpi) you’re using; always consult your prepress service provider before making production decisions. Because commercial printing requires large, high-resolution images, which take more time to display while you’re working with them, you may want to use low-resolution versions for layout and then replace them with high-resolution versions at print time.

In Illustrator and InDesign, you can work with low resolution versions by using the Links panel. In InDesign you can choose either Typical or Fast Display from the View > Display Performance menu; in Illustrator you can choose View > Outline. Alternatively, if your service provider supports Open Prepress Interface (OPI), they may provide low-resolution images to you.

Desktop printing

Desktop printing usually requires images within the range of 72 ppi (for photographs printed on a 300 ppi printer) to 150 ppi (for photographs printed on devices up to 1000 ppi). For line art (1‑bit images), make sure that the resolution of your graphics matches the resolution of the printer.

Web publishing

Because online publishing generally requires images with pixel dimensions that fit the intended monitor, the images are usually less than 500 pixels wide and 400 pixels tall, to leave room for browser window controls or such layout elements as captions. Creating an original image at screen resolution—96 ppi for Windows–based images, and 72 ppi for Mac OS–based images—lets you see the image as it will likely appear when viewed from a typical web browser. When you’re publishing online, the only times you’re likely to need resolutions above those ranges are when you want viewers to be able to zoom in for more detail in a PDF document, or when you’re producing a document for printing on demand.
