FAQ about print DPI upscaling

What is DPI and why does it matter for print?

DPI (dots per inch) describes how dense a printed image will look. Higher effective DPI usually produces sharper results—especially for text and fine details.

How does the DPI calculator help?

It helps you plan your upscaling decision by comparing your image resolution to your target print size so you don’t guess blindly.

Do I need design software?

No. This landing page includes a simple calculator you can use right away, then it points you to the browser upscaling workflow.

Is the output shareable and easy to export?

Yes. The workflow is designed for practical export so you can move from planning to exporting quickly for print or client review.
