Loona Poster & Flyer Maker — Free A4, Square & Story Poster Designer
School events, shop sales, community announcements and social posts all need a poster that looks designed, not typed. Start from a template, swap in your words, drag things into place — and share or print within minutes.
How to use the Poster / Flyer Maker
- Choose your poster size — A4 for printing, Square or Portrait for social feeds, Story for full-screen stories, Landscape for screens and banners.
- Load a starter template (Big Sale, Community Event or Quote) or begin with Add text and Add rectangle / circle.
- Click any block to select it; drag to move it, drag its bottom-right corner to resize, and use the editor below the canvas for text, size, colour, alignment and exact dimensions.
- Optionally set a background colour or upload a background photo, then press Download poster PNG.
How it works
The poster is a stack of blocks — text blocks with font size, colour, bold and alignment, and shape blocks — rendered onto a canvas at the exact pixel size you picked, so the export is ready to post or print without further resizing. A background photo is cover-fitted to the whole canvas. Selection, dragging and corner-resizing are handled with pointer and touch events, and blocks are clamped so they can never be dragged off the canvas.
Worked example
A shop owner picks the Square size and the Big Sale template, changes the headline to "Winter Clearance", moves the gold circle behind the words "SHOP NOW", and downloads a 1080 × 1080 PNG that goes straight onto the shop page and WhatsApp status.
Frequently Asked Questions
Which size should I print?
Choose A4 portrait — it exports at the A4 ratio (794 × 1123 px), suitable for home and shop printing. For social media, use Square (posts) or Story (full-screen).
Can I use my own photo as the background?
Yes — upload it with the Background image picker. It is cover-fitted to the poster and stays on your device.
How do I move or resize a block?
Click the block to select it, drag it to move, and drag the small square at its bottom-right corner to resize. Exact width and height can also be typed in the editor.
Is the poster maker free?
Yes — completely free, no sign-up, no watermark, and your design never leaves your browser.
Can I save my poster to edit later?
Download the PNG for the finished poster. The editor keeps your work while the tab stays open; for a new design, reload a template and adjust.
