How I Built an After Effects Tool to Copy-Paste Transparent Images Straight From the Web

We have all been trapped in the exact same tedious asset preparation loop.

You are working on a motion graphics layout or a rough storyboard animatic inside After Effects. You find the perfect reference image, texture, or product asset in your web browser. You right-click, save it to a chaotic Downloads folder, locate the file, import it into your AE project bin, drag it into your active composition, and then manually draw a rough pen-tool mask to get rid of the background.

If you want it to look decent, you might even have to do a round-trip export into Photoshop just to run a quick selection tool.

It is a disjointed, frustrating workflow killer. I got completely tired of doing it every single day, so I decided to write an automation tool to bypass it completely.

I call it PasteRemoveBG.

The Workflow: Just Copy and Paste

The entire goal of building this extension was to make asset handling invisible.

Instead of downloading anything, you just right-click and copy any image from Chrome, Safari, or your local Finder window. You jump over to After Effects, open the extension panel, and press Paste (or hit Cmd+V).

The panel automatically reads your machine’s system clipboard data, hands it off to a localized background pipeline to isolate the main subject, strips out the background completely, saves a high-quality PNG asset, and drops it straight into your active composition timeline as a layered element.

No round-trips, no manual masking, and no cluttered desktop folders. You just copy, paste, and keep animating.

Why I Built It to Run 100% Locally

When looking at existing background removal tools, almost all of them rely on cloud-hosted APIs or monthly subscription credits. I didn’t want to deal with network latency, usage caps, or paying a monthly fee just to process quick creative layout frames.

Because of that, I engineered the backend of the tool to process everything completely offline, right on your local hardware:

• Local Inference Pipeline: The panel utilizes a localized ONNX runtime environment directly on your machine.
• Smart Edge-Detection: It combines advanced structural segmentation models like IS-Net and u2net with Depth Anything V2 to handle spatial plane analysis. This means it accurately separates the foreground from the background even when the subject shares nearly identical colors with its surroundings.

• Apple Silicon Optimization: For modern Mac setups running macOS 14+, the script hooks directly into Apple’s native Vision Framework, routing the background extraction passes straight through your Mac’s physical Neural Engine for near-instant execution.

Multiple Modes: Transparency, Fills, and Direct Pasting

While building the core clipboard mechanics, I realized that workflow flexibility matters just as much as background removal. Sometimes you don’t want to isolate a subject — you want to remove a distraction to get a clean background texture, or you just want a blazing fast way to import standard images without touching your file manager.

To handle this, I split the extension layout into three distinct operational modes:

remove,fill and original

1. Remove BG: The core automated segmentation engine to isolate subjects instantly.
2. BG Fill: A content-aware workspace that lets you quickly patch over specific areas to clean up plate layouts.
3. Direct Paste: Bypasses all processing pipelines to instantly drop the raw clipboard image directly onto your active composition timeline as a standard layer.

Reconstructing Moving Context

Taking it a step further, the background engine isn’t just restricted to static images. By processing visual structures natively, it provides a solid foundation for prepping clean plates and layers that seamlessly align with dynamic camera elements or complex tracking fields.

Keeping It Accessible to the Community

I wanted this to be a tool that actually saves time for individual creators and studios alike.

The core version of PasteRemoveBG is completely free ($0). It houses the primary clipboard-to-composition asset extraction workflow along with four distinct local AI models and Depth Anything V2 masking support.

For editors who want the advanced content-aware background reconstruction engine, the custom mask brush tool, and Ultra-HD tiling refinement passes, I put together a premium Pro tier for just a flat, one-time fee of $5.

No ongoing subscription hooks, no hidden data tracking, and no external rendering queues. Just your raw clipboard assets mapped directly to your active timeline boundaries.

If you want to experiment with the workflow loop or try it out in your own After Effects setup, you can grab the package files directly over on my shop storefront:
