PDF vs JPG vs PNG: which to use when

PDF, JPG and PNG solve different problems. Using the right one keeps files small and appropriate.

Use PDF for documents

Multi-page, text-based content that must look the same everywhere and stay editable-adjacent belongs in a PDF.

Use JPG for photos

Photographs compress well as JPG with little visible loss. Avoid it for sharp text.

Use PNG for graphics

Screenshots, logos and line art with crisp edges or transparency belong in PNG.
