Check image resolution (DPI)

The DPI subtab in the Review tab shows the print resolution of each image you select. Aim for 300 DPI. Anything from 150 to 600 DPI passes. To have problems flagged for you, run Preflight. Checking the numbers is a Pro feature.

Check image DPI

1. Select one or more layers with an image fill on the canvas. Images inside a frame or group are included.
2. Click Check DPI. Each row shows its DPI.

On the free plan, Check DPI opens the upgrade screen.

Each row shows an image's DPI. Error means the plugin couldn't read the image, and Mixed means the layer has several image fills (see Inspect images with several fills). Click a layer's icon to scroll the canvas to it.

Know what a good DPI is

Aim for 300 DPI for sharp print. Anything from 150 to 600 DPI is fine. Below 150 DPI an image may look blurry in print, and above 600 DPI it makes the PDF heavier without looking sharper. Turn on Downsampling when you export to bring a very high DPI down.

Fix a low DPI image

Making an image smaller on the canvas raises its DPI, and making it larger lowers it.

1. Replace the image with a larger source, or make it smaller on the canvas.
2. Select it again and click Check DPI.

Inspect images with several fills

A layer with more than one image fill reads Mixed. Open its row to see each fill with its own DPI, with the top fill first.
