Why convert PNG to PDF?
PNG is the usual format for screenshots, charts and exported slides. When you need to send them as a single document, a PDF is easier to read, print and attach than a folder of images.
PNGs are embedded losslessly, so small text in screenshots stays perfectly sharp in the PDF.
