Eight directions are supported: PDF → DOCX (Word) and DOCX → PDF, PDF → XLSX (Excel) and XLSX → PDF, PDF → PPTX (PowerPoint) and PPTX → PDF, PDF → images (PNG/JPG per page) and images → PDF (multiple JPG/PNG/TIFF files combined into a single multi-page document). That covers most office workflows: contracts are easier to edit in Word, price lists and reports in Excel. Slides belong in PowerPoint, while scans and photos get bundled into a single PDF for submission.
Text-based PDFs and Office files convert with little loss: paragraphs, simple tables, headers and footers stay in place. Complex layouts (multi-column typesetting, footnotes, charts, technical drawings) may shift slightly – that is a PDF format limitation, not a service one. And scanned PDFs without OCR convert to a Word file with blank pages (only the image is visible), so for those files run OCR first and convert afterwards.
In practice: a single number on a scan is faster to fix in the PDF editor than via a round-trip through Word. When assembling a PDF from photos of receipts or a passport, the 'images → PDF' direction beats stitching pages manually. And if a recipient asks for a 'plain PDF' while you only have DOCX or XLSX – convert before sending, otherwise fonts or cell values may shift on their side.
