How to Import Illustrator Files into After Effects

Importing layered vector artwork from Adobe Illustrator into Adobe After Effects is a fundamental workflow for motion designers. This guide explains how to properly prepare your Illustrator (.ai) file, import it as an editable composition, preserve vector sharpness, and convert artwork into native shape layers for advanced animation.

1. Prepare the Illustrator File

Before bringing your artwork into After Effects, it must be structured properly:

  • Organize Top-Level Layers: After Effects only recognizes top-level layers as individual assets. Sub-layers, groups, and clipped masks within a single layer will be flattened into one layer. Open the Layers panel in Illustrator, select your main layer, click the panel menu (three lines), and choose Release to Layers (Sequence). Drag those layers out so they are all top-level layers.
  • Name Your Layers: Descriptive names assigned in Illustrator carry over directly to After Effects, making navigation much simpler.
  • Set the Color Mode to RGB: Go to File > Document Color Mode > RGB Color. After Effects works natively in RGB; importing CMYK assets can lead to color shifts.
  • Save the File: Save the file as a standard .ai file with Create PDF Compatible File checked in the Illustrator Options dialog.

2. Import into After Effects

  1. Open After Effects and go to File > Import > File... (or press Ctrl+I on Windows, Cmd+I on macOS).
  2. Select your prepared .ai file.
  3. At the bottom of the import window, find the Import As dropdown menu.
  4. Choose Composition - Retain Layer Sizes.
    • Composition - Retain Layer Sizes creates a composition matching your Illustrator artboard and sizes each layer's bounding box to the artwork itself, placing anchor points at the center of each individual element.
    • Do not select Footage, as this will merge your layers into a single flat image.
  5. Click Import.

3. Maintain Vector Sharpness

When you open the newly created composition, your artwork is treated as vector footage, but scaling it up may cause pixelation by default.

To prevent pixelation:

  • Locate the Continuously Rasterize switch (indicated by a small sun icon) in the timeline panel.
  • Check this box for every imported Illustrator layer. This forces After Effects to recalculate the vector paths at any scale or camera depth, ensuring perfectly crisp edges.

4. Convert to Native Shape Layers (Optional)

If you need to animate individual vector paths, use shape layer animators (such as Trim Paths or Repeater), or apply layer-specific modifiers:

  1. Select the Illustrator layers in your timeline.
  2. Right-click and select Create > Create Shapes from Vector Layer.
  3. After Effects will generate native Shape Layers with full path data and automatically hide the original Illustrator layers.
