Free AI Poster Generator from Text or Images
Describe the poster you need or upload a reference image. Img2.AI helps you create polished posters for products, events, brand announcements, social campaigns, education, and creative projects—then refine the text, layout, and size.
Create a Complete Poster Not Just an AI Image
Img2.AI creates a poster around your message—not just an image with empty space for text. Start with a brief or reference image, then refine the wording, visuals, composition, layout, and size for the channel where the poster will appear.
You do not have to begin with a fixed template. Describe what the poster needs to communicate, explore a visual direction, keep the elements that work, and edit the design before downloading a high-resolution version for digital use or printing.
Why Create Posters with Img2.AI?
Start with Text, an Image, or Both
Begin with a written brief, upload a visual reference, or combine both. Use a product photo, logo, portrait, character, artwork, or existing design to guide the result.
Keep the Main Visual Consistent
Tell the AI which product details, brand elements, faces, characters, colors, or artistic qualities should remain recognizable in the new poster.
Edit the Message and Layout
Refine the poster's text, hierarchy, placement, and composition after generation so the final design communicates the right message.
Create for Different Channels
Adapt one poster direction for portrait, story, square, landscape, or custom formats across social media, ecommerce, events, and print.
Explore More Than One Direction
Generate alternative compositions, visual styles, and campaign directions without rebuilding the poster from the beginning.
Download in High Resolution
Export a high-resolution version for digital use or printing, then confirm the final production requirements before publishing or sending it to a printer.
