Use PDF for complete documents and multi-page files. Use PNG for screenshots, transparent graphics, interface images, and sharp flat artwork. PNG can preserve crisp edges better than JPG, but it is still an image format and does not keep document features like selectable text or form fields.
For many document upload tasks, the receiving site decides the format. If it asks for PDF, keep the document as PDF. If it asks for an image, export or capture the needed page as an image and check whether JPG or PNG is accepted.

Step-by-step guide
Identify whether your file is a document or an image. Contracts, forms, reports, and multi-page scans usually belong in PDF. Screenshots and graphics often belong in PNG.
Check whether transparency matters. PNG supports transparency, which is useful for logos and design assets. PDF can contain transparent elements, but it is not always accepted by image upload fields.
Compare file size. PNG can be large for photos because it stores detail differently. For ordinary photos and scanned pages, JPG is often smaller than PNG.
Use PDF when page order matters. A PNG is one image, so a five-page document would become five separate image files unless you combine them later.
Preview the final file in the destination workflow. A format that looks right on your device can still be rejected if the portal only allows specific extensions.
Practical tips
Choose PNG for screenshots with text, interface elements, icons, and simple graphics because edges often stay crisp.
Choose PDF for paperwork that needs page size, page order, and print consistency.
If a PDF page must become an image, JPG is usually more widely accepted than PNG for general uploads.
Keep the original document before exporting an image version, especially if the PDF includes searchable text or signatures.
Common mistakes
Do not use PNG for long multi-page documents unless the receiver specifically asks for images.
Do not assume PNG is always higher quality in a useful way. It may create a much larger file without improving a scanned document.
Do not send a screenshot when the receiving organization asks for the original PDF.
Where PDF and PNG overlap
Both PDF and PNG can show a document page visually, but they solve different problems. PDF packages pages and document structure. PNG captures pixels and is best treated as a precise image.
If you are preparing online application files, start with the required format. Convert only when necessary, and review the final result before submitting.
