Promo Poster Maker — type title and body, it's done
Promoting an event, course or product in a feed? A clean vertical poster stops the scroll better than plain text. This scene presets a 3:4 vertical promo layout: type a headline, the key details, and a line of body copy, pick a theme, and export a 1080×1440 image ready to post. Runs locally — no login, no watermark, nothing uploaded.

Why vertical wins in a feed
Feeds scroll vertically, so a 3:4 image takes up the most screen height and is the hardest to scroll past. Landscape and square posters get squeezed into a thin strip where nothing is legible. This scene defaults to 1080×1440 for exactly that reason.
Three-part copy: hook, clarify, act
An effective promo poster is usually three layers: a big headline that grabs attention ("Now enrolling"), a middle line that says what it is (name + seats/dates), and body copy with the key details and a call to action (how to join, when it closes). The layout maps to those three layers — you just fill them in.
Want people to scan and sign up?
Once you've added a call to action ("scan to join," "closes Sunday"), generate the QR code separately and place it on the poster or in the comments. For a clean, downloadable event or payment QR, use QR Cat and pair it with this poster.
Frequently asked questions
What size suits a promo poster?
A 3:4 vertical, commonly 1080×1440 px, takes up the most height in a vertical feed. That's the default here.
How much body text can I add?
Body text wraps and scales, but a poster is a hook, not a manual. Two or three lines for the essentials; save the rest for the page people land on.
It's a marketing poster — is my content private?
Yes. All compositing happens locally in your browser; your title and body are never uploaded — which matters most for commercial promos.
