Convert pictures to PDF on Mac and Windows using a professional, free PDF creator for accurate, seamless results.



I. What is a PDF file? Why convert pictures to PDF?

PDF (Portable Document Format) is a file format developed by Adobe for file exchange. It offers a more vivid, accurate, and intuitive representation of content compared to traditional formats like txt, doc, and xls. PDF files are more readable and realistically display the original content. The display size can be adjusted, and the content can be edited and saved using conversion tools, providing a convenient and personalized way of using files.
PDF files offer numerous advantages over other electronic formats. They can encapsulate text, fonts, formats, colors, graphics, and images independently of devices and resolutions in a single file. Additionally, PDFs can include elements like text links, sounds, and dynamic images. They support extra-long files, boast high integration and security reliability, and are generally smaller than most other file types, making them easy to transmit and store. PDFs are also suitable for multi-processor systems, making them a preferred format for saving documents.
The pictures include jpg, bmp, tiff, psd, gif, png, and other formats. These formats are prone to issues like image blur, distortion, and content loss during transmission. Converting the pictures to PDF format ensures the integrity of the content across different platforms.
