Introduction to Image to PDF Conversion

Converting images to PDF is a common task for professionals, students, and businesses. Whether you are creating portfolios, archiving documents, or preparing presentations, combining multiple images into a single PDF file simplifies sharing and organization.

Why Convert Images to PDF?

Image Preparation

1. Optimize Image Size

Resize images to appropriate dimensions before conversion. For documents, 1200-1600px width is typically sufficient. Use our Image Resizer to optimize images first.

2. Choose Appropriate Format

• JPEG: Best for photographs and complex images
• PNG: Best for screenshots, text, and graphics

3. Maintain Consistent Dimensions

Images with similar dimensions create more professional-looking PDFs. Consider cropping or resizing to standard aspect ratios.
