PNG is a lossless image format, but it is still just an image. When you need to share screenshots, diagrams, or graphics as formal documents, PDF is the expected format. PDFs maintain exact layout and dimensions across all devices and operating systems.
Converting PNG to PDF is especially useful for screenshots of bug reports, design mockups, scanned documents, and any image that needs to be presented as a professional document. The lossless PNG quality is fully preserved in the PDF output.

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free alternative to GIF. It supports full-color images with an alpha channel for transparency. PNG files preserve every pixel exactly, which makes them ideal for screenshots, logos, UI elements, and graphics with sharp text. The trade-off is file size: PNG images are typically 3-5x larger than equivalent JPG files for photographic content.
PDF (Portable Document Format) was created by Adobe in 1993 and became an ISO standard in 2008. It is a universal document format that preserves exact layout, fonts, images, and formatting regardless of the device or operating system used to view it. PDFs can contain multiple pages, embedded fonts, vector graphics, and interactive elements. It is the global standard for document sharing and archiving.
