Why we like it

Auto Crop earns its place in the toolfarm library as a native After Effects utility focused on one job: cropping compositions to their content with pixel-perfect accuracy based on the alpha channel of every layer.

What is Auto Crop?

Auto Crop is a native After Effects plugin that automatically resizes a composition to match the size of its content. You can crop at the current frame, or have it analyze the entire composition and crop without cutting off any animation. With Auto Crop 3, you can also crop the current comp without it needing to be a pre-comp.

The plugin bases its crops on the alpha channel of every layer in a composition, catching even a single partially visible pixel and including it in the crop dimensions. If a composition contains animation, Auto Crop can examine the full duration to find the smallest possible size without losing detail. When a composition is used across multiple other comps, every instance is adjusted so the new size doesn't affect any visuals. If you move layers outside the composition bounds, you can expand the composition and crop it at the same time.

Rebuilt from the ground up as a native plugin, Auto Crop offers faster speeds, even when cropping several layers at once. Customization options include a layer menu with keyboard shortcuts, an optional script UI panel, and a preferences screen. It runs on After Effects from CS6 through 2025.

Who is Auto Crop best for?

Auto Crop is best for after Effects artists who need to crop compositions down to the size of their content, whether at a single frame or across an animated sequence.

How much does Auto Crop cost?

Auto Crop is completely free to download and use.

Frequently asked questions

Which After Effects versions does Auto Crop support?

Auto Crop is compatible with a wide range of After Effects releases, from CS6 through CC and up to the 2025 version. The full list covers CS6, CC, CC 2014, CC 2015, CC 2015.3, CC 2017, CC 2018, CC 2019, and 2020 through 2025. If you're running one of these supported versions, you can install the plugin and use it to crop compositions to the size of their content. For the latest compatibility details, check the developer's page.

Does Auto Crop require the composition to be a pre-comp?

Auto Crop no longer requires the composition to be a pre-comp. With Auto Crop 3, you can crop the current comp directly, without it needing to be nested inside another composition first. You can still crop compositions that are used across multiple other comps, and every instance is adjusted so the new size doesn't affect any visuals. The plugin can also crop at the current frame or analyze the entire composition to avoid cutting off animation.

Does Auto Crop work with compositions used in multiple other comps?

Auto Crop handles compositions that are used across multiple other compositions without a problem. After cropping, every instance of the composition is adjusted so that the new size doesn't affect any visuals. The plugin bases its crops on the alpha channel of every layer, including even a single partially visible pixel, and it can examine an entire composition's duration to find the smallest possible size without cutting off any animation details.

Is Auto Crop free to use?

Auto Crop is listed here as free. For current licensing terms and any details specific to your setup, check BatchFrame Software's page. The plugin has been rebuilt from the ground up as a native After Effects plugin, and it runs on releases from CS6 through the 2025 version, so most recent installations should be able to run it. Once installed, you can use it to crop compositions to the size of their content at the current frame or across an entire animation.
