How to use the AI poster generator
Learn more about our AI poster generator
A poster gives people the what, when and where at a glance. It works on a feed, in a Story and as the first thing visitors see on your Linktree.
Type a sentence about your poster, such as "Open mic night this Friday 8pm at The Loft, free entry". Choose a style, then pick a size. The generator gives you four designs. Change any of the text or the palette, then download the one you like.
Pick the right size
- Portrait post (1080 × 1350) fills the most space in Instagram and Facebook feeds.
- Square (1080 × 1080) works almost anywhere, including link thumbnails.
- Story (1080 × 1920) fits Stories, Reels and TikTok.
- Linktree background (1000 × 2000) matches the 1:2 crop Linktree uses for profile wallpapers.
- Landscape (1920 × 1080) suits a 16:9 profile header or a featured link.
- Poster (1000 × 1500) is a classic 2:3 shape for Pinterest or printing.
You can switch sizes after generating without starting again.
Write a description that works
Include the essentials: what it is, when it happens, where it is and what people should do next. The AI only uses details you give it. It won't make up dates, prices or places, so add them if you want them on the poster.
Add your own photo
Add a JPG, PNG or WebP photo to use behind your text. Your photo stays in your browser and is never uploaded.
AI poster generator FAQ
Is the AI poster generator free?
Yes. You can generate and download posters for free, without an account.
What sizes can I download?
Six sizes: 1080 × 1350, 1080 × 1080, 1080 × 1920, 1000 × 2000, 1920 × 1080 and 1000 × 1500 pixels.
Can I use a poster on my Linktree?
Yes. Use the Linktree background size for your profile wallpaper, the landscape size for a header or featured link, or square for a link thumbnail. Each file is a JPG or PNG under 8 MB, well within Linktree's upload limits.
Can I edit the text?
Yes. After generating, change the headline, subheadline, details, call to action or palette. The poster updates instantly.
Does the AI make the images?
AI writes the copy and picks a layout and palette. The poster itself is drawn in your browser, so the text is always sharp and spelled correctly.
Are my photos uploaded anywhere?
No. Your photo stays on your device. Only your text description is sent to generate the copy.
Can I print my poster?
Yes. The 1000 × 1500 poster size works for small prints. For large prints, check the size your printer needs.
