How to Make a Professional Poster Online
The ZeeSharp Poster Generator runs entirely in your browser — no software to install, no account required. Start from a blank canvas or pick one of the six built-in templates, then layer in text, shapes and your own images. Every change is instant, and your design never leaves your device.
Supported Canvas Sizes
- Instagram Square (1080×1080 px) — the standard format for feed posts.
- Instagram / TikTok Story (1080×1920 px) — full-screen vertical format.
- A4 Portrait & Landscape (794×1123 / 1123×794 px) — print-ready at 96 dpi; export at 2× for 192 dpi.
- YouTube Thumbnail (1280×720 px) — recommended 16:9 thumbnail size.
- Twitter Post (1200×675 px) — inline image card format.
- Facebook Cover (1640×924 px) — covers the full header area across devices.
- Custom — enter any width and height up to 4000×4000 px.
Design Tips for Effective Posters
- Hierarchy matters — use one dominant headline in a large, bold font. Support it with a smaller subheading and body text. Keep the visual weight intentional.
- Limit your colours — two or three colours keep a design clean. Use the background gradient and text colours from the same palette for cohesion.
- Use contrast — dark text on a light background, or white text on a dark or vivid background. The shadow toggle on text layers adds legibility on busy backgrounds.
- Leave breathing room — don't fill every corner. Empty space directs the viewer's eye to what matters most.
- Export at 2× for print — the 2× export option doubles the resolution, which is suitable for most office and consumer printers.

Yes. Click "Upload Image" under Add Element to add a PNG, JPG or WebP image as a resizable, moveable layer. You can also upload a background image via the Background section. All images are processed locally — nothing is sent to any server.
Yes. There are six built-in templates: Bold Promo (dark background with bold white type), Clean Minimal (white with refined typography), Vibrant Event (vivid gradient with decorative shapes), Corporate (navy and gold professional layout), Sale Offer (high-energy red/orange deal layout), and Travel (teal lifestyle aesthetic). Each loads instantly onto the canvas.
Click the Undo button in the toolbar, or press Ctrl+Z. You can step back up to 30 actions. Ctrl+Y or Ctrl+Shift+Z redoes. Ctrl+D duplicates the selected layer. Delete or Backspace removes the selected layer. Arrow keys nudge a selected layer by 1 px; hold Shift for 10 px steps.
Choose 1×, 2× or 3× in the Export panel. At 1× you get the native document size (e.g. 1080×1080). At 2× every dimension doubles (2160×2160) — suitable for sharp print output. At 3× you get triple resolution for high-quality large-format printing.
Yes. Select “Save project” above the editor to download an editable ZeeSharp JSON project. Use “Open project” later to restore its canvas, background and layers. Keep the project file private because uploaded images are embedded inside it.
PNG is best for text, logos and maximum fidelity. JPEG usually creates a smaller file for photo-heavy posters but does not support transparency. WebP offers strong quality at smaller sizes in modern apps and browsers.
