The Anatomy of a Great Transparent Background API

Wondering what is a great transparent background API, how it works, and if it’s a good option for you? Read to find out.

Even if you know how to make the background transparent in Photoshop, it can be time-consuming, especially when you have to optimize the background for hundreds of photos. This is where Slazzer comes to the rescue. It is an image background optimization app that allows you to remove and alter the background.

It is a one-purpose application that relies on Artificial Intelligence (AI) to do the hard work for you. Simply submit your photograph, and the app will recognize any people in it, clip off the foreground, and provide you with a PNG of your subject with a transparent background to download.

It’s a great example of how cutting-edge machine learning algorithms are being converted into basic consumer solutions. Slazzer uses patented algorithms that are revolutionizing the world of photo editing. Let’s dive deeper to understand the anatomy of Slazzer and how to make images transparent.

Background Removal Deep Learning

Slazzer makes sophisticated technology simple and intuitive for everyday users with no programming or photo editing knowledge. It employs powerful computer vision algorithms to differentiate the foreground subject from the backdrop.

The algorithms may be complex, but they are also super quick, processing about 1 second per megapixel to produce accurate and natural cutouts. Let’s learn more about computer vision algorithms and their relation to deep learning.

Computer Vision Algorithm

Computer vision is a branch of computer science dedicated to simulating portions of the human vision system’s complexity and allowing computers to recognize and analyze things in photos and videos in the same way that people do. Computer vision was only used in a limited manner until recently. However, things have changed.

Artificial intelligence has made significant strides in recent years, surpassing humans in several tasks involving object detection and classification, thanks to breakthroughs in artificial intelligence and innovations in deep learning and neural networks. The amount of data we generate today, which is subsequently utilized for training and improving computer vision, is one of the driving causes behind the expansion of the field.

Deep learning is a powerful computer vision technique. In most cases, developing a good deep learning algorithm entails collecting a significant quantity of labeled training data and fine-tuning parameters like neural network type, number of layers, and training epochs. Deep learning is easier and faster to create and deploy than prior forms of machine learning algorithms.

Therefore, it is used in the majority of today’s computer vision applications. Because of the availability and advancements in hardware and cloud computing resources, deep learning and deep neural networks have progressed from theoretical to practical applications – Slazzer is just one example.

However, keep in mind that a complex algorithm does not mean complex functioning. Slazzer is not only changing picture editing workflows to enhance efficiency, but we’re also assisting organizations and individuals in rethinking design and photography in general.


Slazzer is customer centric. For personal use, you can remove background from images for free with the Slazzer app. On the other hand, if you want to develop a website or a new app with image background optimization capabilities, you can opt for Slazzer transparent background API.

Slazzer provides an API so that others can use the app and algorithms to build top-notch AI solutions. Slazzer REST API opens countless possibilities for developers to integrate image processing capabilities into numerous platforms, including picture editing apps, websites, graphic design interfaces, e-commerce, digital marketing feeds, and more.

The Slazzer application programming interface is based on HTTP. It is also quite simple to use. You simply upload an image and erase the backdrop in a matter of seconds. Moreover, using the Slazzer REST API means you don’t have to worry about the number of photos edited.

Slazzer enables you to focus on designing your apps and websites rather than worrying about infrastructure or scale. Whether you process 100 photographs per month or 10,000 images per hour, cloud-hosted Slazzer has got you covered.

Moreover, there are a variety of API wrappers and libraries for various languages. You can opt for Slazzer’s powerful community-based API wrappers and libraries for Node.js, Python, PHP, Ruby, and other popular programming languages. You can also use our HTTP library for general uses if that’s what you want.

Image Transformation

Wondering what the API Rate limit is or just how many images you can transform using Slazzer? The API can process up to 500 photos per minute in real-time, depending on the megapixel resolution of the incoming image!

However, keep in mind that the Rate Limit will decrease as the input image resolution increases. For example, while the rate limit for 1200 x 800 (1MP) images is about 500images/minute, Slazzer can process only 20 images/ minute if the input image is 6250 x 4000 (25MP). If the API rate limit is exceeded, the error code 429 will be returned. However, Enterprise clients have access to higher API rate limits. Take a look at Slazzer API to check out API Rate Limit details.

When integrating API, you can request two image formats: PNG and JPG. However, keep in mind that PNG images larger than 10 megapixels are not supported by default. If you don’t need transparency, the JPG format is a good choice.
