PNG vs PDF
PNG is an image format. PDF is a document format. Use PNG for a single visual image and PDF when pages should behave like a document.
Quick answer
What you need to know first
Use PNG for screenshots, transparent graphics and image assets. Use PDF for multi-page documents, forms, submissions and files that should print consistently.
The main difference
A PNG is one raster image. A PDF can hold pages, text, images, forms, metadata and links. That makes PDF better for document workflows.
Examples
A screenshot of an app interface is naturally a PNG. A set of screenshots that must be submitted as one file is usually better as a PDF.
