I. PDF and PNG

how to convert pdf to png
Before introducing the conversion of PDF to PNG images, we can first understand what they are and what are their characteristics.
PDF
PDF (Portable Document Format) is the industry standard for document sharing because it creates an exact copy of any file to be copied, including image files. Data such as text, pictures, tables, or videos can be saved in a PDF document, which can completely and accurately display the layout and content of the original document.
Main features of PDF documents:

  • reliability. Documents used as PDFs are guaranteed to be identical to the original document or image when viewed as a copy of the image file. Whether you view it on a computer or a mobile phone, it will not change due to device changes, and always maintain the correct display of graphics or text content.
  • high quality. PDF objects (especially images) can be highly compressed using different compression algorithms without quality loss. When you need to print a document, PDF is the best choice.
PNG
PNG file is an open format without copyright restrictions, and is the most commonly used lossless image compression file format on the Internet. Among other things, PNG files can also contain 24-bit RGB color palettes and grayscale images. This format is ideal for creating web graphics, logos, illustrations, and more. The biggest advantage of PNG is that it supports image transparency, allowing you to easily place illustrations or graphics on colored backgrounds. If the image needs to be edited and saved multiple times, it is recommended that you use the PNG format.
Key features of PNG images:

  • The file size is large. Unlike images such as JPG, which are compressed in the same way, PNG format files are relatively large compared to JPG images.
  • Lossless image quality. The LZW compression used when creating PNGs causes no quality loss, so images can be edited, saved again and again, without performance degradation over time.
Both PDF and PNG have their own characteristics and advantages, and how to use them depends on your actual needs. If you need to convert PDF to PNG losslessly, you can use various methods described below.
