How do PDF and PNGcompare? Here's everything you need to know to choose the right format — and how to convert between them.
Portable Document Format
PDF is the universal standard for sharing documents. It preserves formatting, fonts, and layout across all devices and operating systems. From contracts to resumes, PDF is the format the world relies on.
Portable Network Graphics
PNG is a lossless image format that supports transparency. It was created as an improved, non-patented replacement for GIF. PNG is ideal for graphics, logos, screenshots, and any image where quality preservation is critical.
