Enhance your email signature by adding social media icons. Discover step-by-step instructions to turn every email into a powerful marketing tool.

Ever use an Instagram filter and think, I could make something better than this? Well, you can. Creating your own custom Instagram AR (augmented reality) filter is more accessible than you might imagine, and it’s a powerful way to engage your audience, express your creativity, and build your brand. This guide will walk you through the entire process, from downloading the right software to submitting your first filter for the world to use.
Before we get into the "how," let's quickly cover the "why." Custom AR filters aren't just a fun gimmick, they're a legitimate marketing and branding tool. When someone uses your filter in their Story, your filter's name (and a link to your profile) appears at the top. It’s like a viral, interactive business card.
The main tool for creating Instagram and Facebook filters is Spark AR Studio. It's a powerful - and completely free - software platform developed by Meta. It works on both Mac and Windows.
While you can do a lot with just the software, you might also want some creative assets. These can be simple 2D images or more complex 3D models.
For this tutorial, we’ll start simple and focus on a 2D graphic, which is the perfect entry point for any beginner.
First things first, head over to the Spark AR Studio official website and download the software. The installation is straightforward - just follow the on-screen prompts like you would with any other application.
Once installed, an essential companion app is the Spark AR Player, available for both iOS and Android. This app allows you to test your filters on your own phone in real-time, which is far more effective than just using the simulation on your computer.
Opening Spark AR for the first time can feel a little intimidating, but the layout is surprisingly logical. Let’s break down the main sections you’ll be working with:
The Viewport: This is the large central window where you see a live preview of your filter. By default, it shows a pre-recorded video of a person talking, but you can change this to use your computer’s webcam for a live feed of yourself.
The Scene Panel (Top Left): This is a list of all the objects that make up your AR effect. Think of it like layers in a graphic design program. Every element you add, from a face tracker to a 3D object, will appear here.
The Assets Panel (Bottom Left): This is your media library for the project. It’s where you’ll import your textures (images), materials (which define how an object looks), and any 3D models you might use.
The Inspector (Right Side): When you have an object selected in the Scene or Assets Panel, the Inspector will show you all its properties. This is where you’ll fine-tune everything - changing colors, adjusting sizes, and assigning textures to materials.
Don't worry about mastering it all at once. We'll be using these panels in our walkthrough, and it will start to feel more natural as you build your first project.
Let's make a classic starter filter: a "face paint" or "tattoo" effect that places a graphic on the user's cheeks. This project teaches the fundamentals of face tracking and applying textures.
Open Spark AR Studio. You’ll be greeted with a lot of templates, which are great for learning later on. For now, select "Blank Project" to start from scratch.
We need the filter to know where the user’s face is. For that, we use a Face Tracker.
You’ll now see a `faceTracker0` object in your Scene Panel. Anything attached to this object will move, rotate, and scale with the user’s face.
Now, we need something to "paint" our design onto. The Face Mesh is a 3D model that perfectly wraps around a face detected by the tracker.
You should immediately see a checkered mask appear on the person in the Viewport. This demonstrates that your Face Mesh is correctly attached to the Face Tracker. The checkered pattern is just a placeholder - it means there’s no material assigned to it yet.
Materials define the surface of an object - its color, texture, and how it reflects light. We need a Material for our Face Mesh.
Now, let's connect the material to the mesh.
The checkered mask in the Viewport will turn into a plain white mask. We're getting closer!
This is where your creativity comes in. Create your design in a program like Canva or Photoshop. It could be freckles, a small logo, abstract shapes, whatever you want. Important: Save it as a .PNG file with a transparent background.
You can download a face reference template from the Spark AR website to help you place your design accurately over the cheeks, forehead, or chin. Once your design is ready:
The final step is to tell our Material to use the image we just imported.
Boom! Your design should now be perfectly mapped onto the face in the Viewport. It will move with them as they talk and turn their head. You just made your first AR filter.
You should always test your filter on a real device. The camera quality, lighting, and diverse faces can reveal issues you won't see in the simulator.
You can also send a temporary test link to friends or colleagues via Instagram to get their feedback before submitting it. This is a great way to catch any bugs.
Once you’re happy with your filter, it’s time to share it with the world. Submitting is done through the Spark AR Hub.
From Spark AR Studio, navigate to File > Export. A window will pop up to optimize file sizes. Follow the prompts and export the project. It will save a single file with the extension `.arexport`.
In the Spark AR Hub dashboard, click "Publish an effect," and follow the guided steps.
You’ll need to provide some information:
Once everything is filled out, hit submit. Your filter will go into a review queue. The approval process can take anywhere from a couple of days to over a week, depending on the complexity of your filter and how busy the review team is. You'll get a notification once it's approved and live on your Instagram profile.
Creating your own Instagram filter moves you from being a passive content consumer to an active world-builder. With Spark AR Studio, what seems complex is just a series of logical steps, offering a rewarding way to express your brand's unique identity and connect with your audience on a whole new level.
Once you’ve crafted the perfect AR filter to drive engagement, you'll want to integrate it into a broader content strategy. This is where a focused tool for modern social media becomes essential.
