Preserve Transparency, Vector Crispness, and True Colors in PDF
PNG is the go-to format for high-detail screenshots, diagrams, software wireframes, and graphics with transparent alpha channels. However, sharing loose PNG files can lead to unwanted background tiling or formatting issues in image viewers.
Converting your PNG images into a PDF packages them into an organized, standard document with crisp edges, consistent margins, and predictable printing across all platforms.
