Removing image backgrounds manually can be a tedious and time-consuming task, especially for bloggers or content creators who need to process multiple images quickly. With AI powered tools, this process becomes fast, precise, and effortless. In this article, we will explore how to create an AI image background remover with a before-after comparison feature using the free API from Cutout. Liadigi will guide you step by step to build a tool that works directly on Blogger using simple HTML, CSS, and JavaScript without complex backend setup. The goal is to make it understandable for anyone, even beginners, while ensuring the output is responsive, modern, and functional for real-world blogging purposes.

Understanding AI Background Removal

AI background removal is a technology that automatically detects the subject of an image and separates it from the background. Traditional methods require careful selection and masking, which is often time-consuming and prone to errors. AI models, however, can analyze images pixel by pixel and generate clean separation efficiently. This process allows bloggers to quickly replace, remove, or modify backgrounds, making images more appealing for articles, social media, or product displays. Liadigi emphasizes that with the before-after feature, users can instantly compare the original image with the edited version, ensuring accuracy and satisfaction before publishing.

Why Use Cutout API

Cutout API provides a free, reliable, and fast solution for automated background removal. It supports various image formats and offers additional features such as background replacement and transparent outputs. Using Cutout API through JavaScript enables integration directly into web pages, meaning bloggers can create interactive tools without the need for servers or heavy libraries. Liadigi points out that its open access and easy API calls make it ideal for those who want to automate repetitive image editing tasks while maintaining professional results. It also allows real-time operations, which is perfect for before-after comparisons in dynamic web interfaces.

Preparing the Blogger Environment

Before building the widget, you need to set up your Blogger page or post where the tool will reside. Open the HTML editor and prepare a container for the image uploader, the before-after display, and the action buttons. Liadigi recommends creating a separate testing page initially to avoid interfering with your main content. Ensuring proper layout and container sizes is essential for a smooth user experience. Once prepared, the HTML structure will act as a base for integrating JavaScript functions that interact with Cutout API to perform background removal and update the before-after display seamlessly.

Getting the API Key

To access Cutout API services, you need a valid API key. Visit Cutout API Secret Key Page to generate your free API key. This key is unique and allows your widget to authenticate requests to the AI service. Liadigi stresses the importance of keeping the key secure while testing and development. Once integrated into your JavaScript code, it enables the widget to send image data to Cutout API and receive processed results efficiently, allowing users to instantly see the before-after transformations directly within Blogger without needing extra downloads or external software.

Steps of Creation

Creating the AI background remover involves building the interface, connecting to the API, and handling responses for dynamic display. Liadigi suggests a systematic approach to ensure the tool works reliably. You will use HTML for structure, CSS for design and responsiveness, and JavaScript to manage API requests and display before-after images interactively. Following these steps will allow even beginners to implement a fully functional tool that integrates seamlessly into Blogger. Testing and tweaking responsiveness ensures that users on all devices experience smooth and consistent results.

1. Open your Blogger HTML editor and create a new post or page for the background remover widget.
2. Add HTML structure for image upload, before-after display, and action button elements.
3. Use CSS to style the container and buttons, prioritizing green for the main action button and centering the text for clarity.
4. Implement JavaScript to capture uploaded images and send them to Cutout API using your API key.
5. Handle the API response and update the before-after display dynamically to show the original and processed images side by side.
6. Test with multiple images to ensure the before-after comparison functions correctly on different screen sizes.
7. Refine layout and responsiveness to enhance user experience before publishing the page live.
