Pick a workflow: render PDF pages, extract text, build a PDF from images, merge, split, or peek at a PPTX. Everything runs locally in your browser; PPTX is preview-only because full PPTX → PDF needs a server-side renderer.
Pick an operation
Full PPTX → PDF conversion isn't possible in the browser (it needs LibreOffice on a server). The PPTX option here just extracts the images embedded in the deck and the document preview thumbnail.
