What Is PNG Encoding Format?

PNG (Portable Network Graphics) encoding format is a raster graphics file format that uses lossless compression. It supports transparency and a wide range of colors, making it ideal for web graphics. PNG uses the Deflate compression algorithm to reduce file sizes without losing image quality. It supports various color depths, including grayscale, indexed color, and truecolor, and can store metadata like gamma correction and color profiles. PNG is widely used for its balance of quality and file size.

Why should we convert PNG to PDF?

Converting PNG to PDF is beneficial because PDF files maintain consistent formatting across devices, support multiple images or pages in a single document, and offer advanced features like text search, annotations, and encryption. PDFs are widely used for sharing and printing due to their portability and reliability, while PNG files are better suited for individual images with transparency. Converting to PDF enhances document management and presentation.
