Upscale AI images to print size
AI art comes out at 1–2K pixels. Printing needs more. Fix it free, in your browser.
Free · no watermark · your designs stay on your device
Images from Midjourney, ChatGPT, Ideogram and most AI generators come out around 1024–2048 pixels. That looks great on screen and falls apart in print — a t-shirt, poster or Etsy printable needs several times more resolution.
MerchForge includes a free AI upscaler that enlarges your image up to 4× while keeping edges clean — a 1024px design becomes 4096px, a 2048px design becomes print-ready. Pair it with an exact output size (like Amazon Merch's 4500×5400, or any custom size up to 10,000px) and the artwork is upscaled to fill it.
Unlike most online upscalers there's no credit system, no watermark and no upload — the AI model runs on your own device, in the browser. Batch a whole set of designs in one go.
How it works

Up to 4×, automatically chosen from your image's size. Add background removal, halftone or an exact print size in the same pass.
- Step 3Download sharp, print-ready files
Clean edges, 300 DPI metadata, compressed PNGs with transparency kept.

Common questions
How much bigger can it make my image?
Up to 4× the original resolution — a 1024×1024 AI image becomes 4096×4096. With a target size set (like 4500×5400) it upscales to fill that exact canvas.
Which AI generators does it work with?
All of them — Midjourney, ChatGPT / DALL·E, Ideogram, Stable Diffusion, Nano Banana and anything else that outputs PNG, JPG or WebP.
Do my images get uploaded to a server?
No. The upscaling model downloads to your browser and runs on your device, so your artwork never leaves your computer.
Is it good enough for print-on-demand?
Yes — it was built for POD sellers. Upscaled exports carry 300 DPI metadata and can be sized exactly for Amazon Merch, Etsy printables, Printful and other platforms.
