Key Features
Multiple poster sizes
Generate poster files for standard sizes including 18x24, 24x36, and more. Each size is output at the exact pixel dimensions required for 300 DPI printing.
300 DPI print-ready output
Every poster file is set to 300 DPI, the industry standard for print production. Files are ready to upload directly to your print provider without additional processing.
Smart crop and fit
The poster maker intelligently crops or fits your image to the target poster ratio, keeping the focal point centered and preserving the composition of your artwork.
Optional mockup generation
Add realistic room-scene mockups to your poster output. Show customers how your poster looks framed and hanging on a wall.
High quality preservation
Your original image quality is preserved throughout processing. No unnecessary recompression or quality loss from source to final print file.
Fast cloud processing
Processing happens on cloud servers. Upload, process, and download your poster files in seconds with no software installation required.
Large Print Ready at every size
Every poster file is sharp at every standard print size — from 16×24" to 24×36" (US) and A4 through A1 (ISO). Customers can confidently print at any size.

When you’d use this tool
Four scenarios where this tool saves the most time:
- Selling 24×36 statement posters as Etsy digital downloads. The 24×36 is the bestselling poster size on Etsy. Drop one source image, set 2:3 portrait, get back a clean 7,200×10,800 file at 300 DPI ready for direct buyer download. Optionally bundle with mockups and a listing PDF in the same upload.
- Custom poster commissions at non-standard sizes. A buyer wants a 22×30 print for a specific frame. Use custom dimensions (22×300=6,600 wide; 30×300=9,000 tall) and the poster maker outputs at exactly that size, 300 DPI stamped. No Photoshop math, no manual export — minutes from order to delivery.
- KDP book cover preparation with bleed. KDP wants 300 DPI with bleed at the trim size. For a 6×9 paperback with 0.125" bleed, set custom dimensions to 6.25×9.25 inches and the poster maker outputs the bleed-inclusive file. KDP trims to 6×9 on print without rejecting the upload.
- Refreshing an old poster source for the modern 24×36 standard. You designed a poster years ago at 4,000×6,000 and want to relist at 24×36 (which needs 7,200×10,800). The poster maker auto-detects the resolution gap and runs AI upscaling as part of the same job, so the output meets the modern 300 DPI standard from one upload.
Common mistakes
Things to watch for, in approximate order of how often I see them:
1. Confusing 2:3 (portrait) with 3:2 (landscape)
Same ratio, different orientation. 2:3 is taller than wide (24×36 portrait); 3:2 is wider than tall (36×24 landscape). Buyers ordering '24×36 portrait' get unhappy if you ship landscape. Always confirm orientation in the listing title.
2. Designing without bleed when shipping to professional print shops
Etsy buyers usually print at home (no bleed needed), but if a buyer takes your file to a professional print shop, they typically need 0.125" bleed each side. Mention this in the listing description and let the buyer add bleed if their print shop requires it.
3. Using a 12 MP source for 24×36 expecting 300 DPI
12 MP (4,000×3,000) is just under a third of the 78 MP needed for sharp 24×36 at 300 DPI. The print will be visibly soft. Either AI-upscale to fill the gap (the poster maker handles this in the same job) or list at a smaller size your source can support sharp.
4. Forgetting that 'large format' may need different DPI tolerance
200 DPI is acceptable for 24×36+ posters viewed from across a room — the eye can't distinguish 200 from 300 at that distance. If your source is borderline, 200 DPI gives you flexibility. For Etsy digital downloads always target 300 DPI since you can't control the buyer's viewing distance.
5. Skipping AI upscaling on borderline-sized sources
A 5,000×7,500 source will print sharp at 16×24 but soft at 20×30 (which needs 6,000×9,000). The poster maker detects this gap and runs AI upscaling automatically when the source is below target. Don't manually skip it — the upscale credit is small compared to the refund risk on a soft print.
