A few practical terms.

This publicly available, free preview helps adults create and print posters locally.

Your content and use

Use images you own or have permission to reproduce. You are responsible for the content, print permissions and your local use. There is no public hosting or sharing feature.

Print results

The tool is provided as available, without a guarantee of accuracy or fitness for a particular use. Check the calibration sheet and seams before printing a full run. Do not rely on this tool for safety-critical plans, regulated measurements or precision fabrication. Mandatory legal rights remain unaffected.

Limits

Input is limited to one JPG or PNG, 20 MiB, 24 megapixels and 12,000 px per side. Export allows up to 100 poster sheets plus one calibration sheet. These resource limits do not guarantee success on every device. Resize the source image locally or reduce poster dimensions or overlap if you reach a limit.

Release status

No subscription, payment or paid entitlement is offered. The site is publicly hosted on Cloudflare Pages as a preview. Physical print dimensions have not been verified on a real device. The preview does not claim independent legal review or production certification.
