Slides want PNG; print vendors want DPI you probably do not need here
A 16:9 deck page rasterized at screen density is already a lot of pixels for Instagram or a website <img>. JPEG will mosquito-noise the title. PNG will not. Convertify4u preserves page aspect — do not let a CMS stretch 16:9 into a square; crop in an image tool if the network demands 1:1. Brochures and catalogs: each page becomes a carousel card. Reports: charts stay readable on a phone if the original type was large enough; 8-pt footnotes will fail at feed size even as PNG. This is Edge-class rasterization for eligible files, free, with ZIP output. If a social platform rejects file weight, compress after, or use Pro HD only when you truly need 300 DPI (usually you do not for feeds). Hidden PDF comments are not a social-safe redaction path — flatten visually by cropping the PNG if needed. Auto-delete after download; you did upload the pitch, so only send decks you are allowed to process.
Spoke versus hub
Hub = general convert. This page is destination thinking: PPT import, website heroes, LinkedIn carousels.
PowerPoint re-import
Insert Pictures per slide from the ZIP. You lose editable text. If you still need to change a title, edit the original deck instead.
