How to Convert InDesign to PDF (INDD to PDF)

Adobe InDesign is the industry standard for layout design. Here's how to convert your INDD files to PDF for sharing, printing, or web distribution.

What is an INDD File?

INDD is Adobe InDesign's native file format, used for:

• Magazine and book layouts
• Brochures and flyers
• Business cards and stationery
• Posters and banners
• Digital publications

INDD files contain linked assets, styles, and layout information that require InDesign to open properly.
