Frequently asked questions

Will PNG transparency convert correctly?
PDF supports transparency — PNG alpha channels are preserved when converting via Preview or Quick Actions. The PDF page background is white by default; transparent PNG areas show the white. To get transparent PDF pages, you'd need professional tools like Acrobat Pro.
Best way to combine multiple PNGs to one PDF?
Quick Actions: select all PNGs in Finder → right-click → Quick Actions → Create PDF. macOS creates a single PDF with one page per PNG, in alphabetical order. To control order, rename files (01.png, 02.png) before converting.
Is there a quality loss converting PNG to PDF?
No — Preview embeds the PNG as-is in the PDF (or recompresses to JPEG for non-transparent images at default quality). For lossless preservation, use the command line: `convert input.png -compress none output.pdf` (ImageMagick).
