How To Easily Create Your Own AI Posters and AI Movie Posters For Free

Updated: Jul 19

Here at AI Art Kingdom, I recently opened my own AI poster shop and decided I would share the experience. With the help of my favorite AI art generator, Leonardo AI, creating AI posters is a fairly easy and straightforward process when you have the right tools for the job. In this article, I will walk you through the steps and tools necessary to generate high-resolution quality AI posters.

What Are AI Posters?


AI posters, or artificial intelligence-generated posters, are digital creations made using AI technology to develop visual designs, color palettes, and layout options. AI assists in content generation as well, merging human creativity with AI capabilities. By utilizing deep learning models, AI analyzes extensive visual data to mimic human artistic styles. This data encompasses photographs, graphics, design elements, and both classic and contemporary art forms.


What is an AI Poster Generator?


Essentially, an AI poster generator is an online AI tool that uses artificial intelligence (AI) to create stunning visuals for posters. AI art generators such as Leonardo AI and Midjourney use machine learning and algorithms to analyze keywords, topics, text, or images. Some AI poster generators can design posters for a variety of purposes, such as event promotions, business advertising, and marketing materials.


Picking The Right AI Poster Generator


I use and highly recommend Leonardo AI for creating AI posters. Here’s why:


1. Easy-to-use dedicated platform: 

The user-friendly interface makes it accessible even for beginners.


2. Built-in Image Upscaler: 

Most AI poster generators produce images at a decent but somewhat low resolution. When it comes to generating and printing posters, you want the highest resolution possible.


Generating AI Posters


First things first, you want to generate an image that is poster-worthy. Using Leonardo AI or any other comparable AI poster generator, I created an image I felt would make a good poster. For a full details, check out Leonardo AI Tutorial: Ultimate Guide to Creating AI Art Like a Pro. For this example, I went with something cute and light-hearted. Just using the PhotoReal V2 model, I entered the text prompt:


"Masterpiece, vintage Renaissance style, animal portrait, kitten, exquisitely dressed, oil painting, light background, centered composition, Leonardo da Vinci, Raphael, Titian, luxurious attire, velvet cape, golden collar, intricate lace, regal posture, soft chiaroscuro, detailed fur texture, rich tapestry background, ornate frame, antique feel, aristocratic elegance, hand-painted quality, depth of expression, period costume."


Here are the results:



Upscaling Your AI Posters Created

Completely satisfied with how this little guy came out, it is now time to get him ready for AI poster creation. The next step is to open up Leonardo AI's Universal Upscaler and add in our newly created AI poster. The key setting to note here is placing the Creativity Strength down to 1; otherwise, the upscaler will alter your final output.


Most AI poster generators create images that are around 1344x1792 pixels, which can produce lower quality, pixelated results when printed. However, after one run through the Universal Upscaler, you will see a jump to 2688x3584 pixels, which is much better for producing high-quality AI posters. A bit on the expensive side, it will cost 80 credits to upscale your image, but once complete, you will have an AI poster worth printing, selling, and hanging up wherever you see fit!

AI-Generated Movie Posters


If you've ever wanted to create your very own movie posters from your favorite films, this can easily be achieved as well. The main addition to the steps detailed above is utilizing Leonardo AI's Image Guidance advanced features, specifically its Character Reference to generate accurate characters inside of your images. Here is a full guide on how to do this: Master Consistent AI Character Creation.


Picking the right prompt for this step is crucial as well. I tried to recreate the old 60's painted movie poster aesthetic using the PhotoReal V2 model and this prompt:


"Masterpiece, best quality, vintage movie poster, 60's spy film featuring Keanu Reeves as John Wick, action-packed, Robert McGinnis James Bond movie posters, Diamonds Are Forever, grainy vintage aesthetic, perfect features, highly detailed, cinematic composition."


Here are some of the results:



Things To Consider


Customize Your AI Posters

One of the best features of using an AI poster maker is the ability to customize your designs. You can edit various elements, such as color schemes, fonts, and graphics, to match your specific needs. One of the best cost effective tools for doing this is Canva. I've used their poster templates and customization options to create promotional designs for my posters along with putting final detail touches on my artwork as well. Whether you're creating posters for business events, personal projects, or advertising campaigns, customization ensures visually appealing posters that make a lasting impression.

Graphic Design Style and Themes

Themes play a crucial role in poster design. An AI poster generator allows you to experiment with different themes, whether it’s vintage, modern, minimalist, or abstract. This flexibility lets you tailor your posters to fit any event or brand identity, making your visuals more impactful and cohesive.


Adding Personal Photos and Graphics

Many AI poster generators, including Leonardo AI, allow you to upload your own photos and graphics. This feature is particularly useful for creating personalized event posters for weddings, birthdays, and corporate gatherings. By incorporating personal elements, your posters will have a unique touch that resonates with your audience.


Promoting Your Posters

Once you have designed and customized your posters, it’s time to promote them. Share your AI-generated posters on social media, your website, or other digital platforms to reach a wider audience. Pinterest can be a great platform for getting eyes on your creations and potentially interest for your website or poster shop in the process. Engaging visuals are more likely to capture attention and drive traffic to your business or event.


AI Poster Shop


Generating your own AI poster designs can be beneficial in a number of ways, from showcasing your business or brand assets to helping promote events and various projects. Selling AI posters is also an extremely fast and efficient way to generate passive income. I recently set up a poster shop on my website. This not only allows me to share my creative work but also provides an additional revenue stream.
