Why turn PDF pages into pictures
Many places that people share things do not handle PDF files well. Messaging apps show PDFs as attachments instead of previews, social media posts accept only pictures, and many websites, online shops and photo printers want image files. Turning each page into a picture makes the content instantly visible almost everywhere, without the receiver needing a PDF reader.
What happens when you convert
Each page of the PDF is drawn exactly as a PDF viewer would show it — text, pictures, colours and drawings — and then saved as a JPG picture. The picture size depends on the quality you choose. At Screen (96 DPI) an A4 page becomes about 794 × 1123 pixels; at Standard (150 DPI) about 1240 × 1754 pixels; and at High (300 DPI) about 2480 × 3508 pixels. Every page becomes a separate file named with its page number, and several pages are downloaded together in one ZIP file, or one by one from the file list.
Choosing the right quality
Pick Screen for quick previews and chat messages, where small files matter most. Pick Standard for most uses: text stays readable when someone zooms in a little. Pick High only for printing or for pages with very small print, because the files are several times bigger.
Common problems and how to fix them
Text looks soft: choose a higher DPI. The picture file is too big for an upload form: use Compress Image or Resize Image to 50KB afterwards. You only need one page: save it first with Extract PDF Pages, then convert just that page. The PDF asks for a password: it must be unlocked before the pages can be drawn.
Good habits
Keep the original PDF for printing and archiving — a picture cannot be searched or edited like text — and hide any private details with Redact PDF before you share pages as pictures.
