What each resolution gives you

A PDF page is measured in inches, so the pixel size follows from the DPI you pick. An A4 page comes out at 1240 × 1754 pixels at 150 DPI and 2480 × 3508 at 300; US Letter gives 1275 × 1650 and 2550 × 3300. A slide exported from PowerPoint in 16:9 is usually 13.33 inches wide, so 150 DPI turns it into an image 2000 pixels wide, plenty for a presentation or a post.

Very large pages such as A3 posters and drawings are held to about 16 megapixels each, so at 300 DPI they come out slightly smaller than the arithmetic says.

Preparing pages for a post or slide

Feeds and chat apps show images around 1080 pixels wide, which for an A4 page falls between the 96 and 150 DPI options. Render at 150 and bring it down with the image resizer; small type stays sharper that way than rendering low. A full page of text is rarely readable at feed size, so crop to the paragraph or chart that matters.

Transparent areas in the PDF are filled with white, and the images carry no text layer, so anything readers need to copy should also go out as text.
