PNG was built for precise, editable graphics: screenshots, interface elements, logos, anything with sharp edges or flat color that needs to survive repeated saves without degrading. PDF was built for documents: pages, print layout, and structure that has to look identical wherever it is opened.
Confusing the two usually shows up as one specific mistake: sending a five-page document as five separate PNG files because "PNG looks sharper," when what was actually needed was one PDF.
Need the page as an image either way?
Export the PDF page as a JPG below — it covers most of the cases where people reach for PNG by habit.
How to tell which one you need
Ask whether the file is a document or an image. Contracts, forms, reports, and multi-page scans belong in PDF. Screenshots and simple graphics belong in PNG.
Check whether transparency matters — PNG supports it, which matters for logos and design assets. PDF can technically contain transparent elements, but image upload fields do not always handle that correctly.
Compare realistic file sizes. PNG can balloon for photographic content because of how it stores detail; for ordinary photos and scans, JPG is usually smaller than PNG.
Remember page order: PNG is always one image. A five-page document becomes five separate files unless you combine them into a PDF afterward.
Where the confusion causes real problems
Using PNG for a long multi-page document, when the receiver never asked for images at all.
Assuming PNG is "higher quality" in a way that matters for a scanned document — it usually just produces a larger file without a visible improvement.
Sending a screenshot when the receiving organization specifically asked for the original PDF, not a picture of it.
Keep documents as documents
Convert only the pages that genuinely need to become images.
FAQ
Is PNG better than PDF?
Not generally — PNG suits certain images, while PDF suits complete documents.
Can PNG have multiple pages?
No. PNG is always a single image.
Is PNG good for scanned documents?
It can look clear, but file sizes are often larger than the same scan saved as JPG or kept as PDF.
Which is better for screenshots?
PNG, especially for anything with text or interface details.
Which is better for official documents?
PDF, unless the receiver specifically asks for image files instead.
