When a page needs to be a picture
PDFs are great for documents and terrible everywhere else: a slide deck wants an image, WhatsApp previews an image, a web page embeds an image, a marketplace listing accepts only images. Converting a page to JPG solves all of those at once — drop the PDF, pick a quality, and every page comes back as a picture. Single-page files download as one JPG; multi-page files arrive as a ZIP with the images numbered in order.
Rendered by a real PDF engine
Each page is drawn by pdf.js — the same rendering engine Firefox uses to display PDFs — running in a background thread of your browser, then encoded as a JPG. Three quality levels cover the usual jobs: Screen (72 DPI) for chat and web embeds where small files matter, Good (150 DPI) for slides and documents, and Print (300 DPI) when the image needs to survive paper. Higher DPI means sharper text and bigger files; 150 is the right default for almost everything.
Converted on your device
The pages people turn into images are often the sensitive ones — a contract clause to quote, a statement line to share, an ID page for a form. Here the rendering happens entirely on your own machine: no copy of the document or its pages is transmitted anywhere, there is no account, no daily conversion cap, and no watermark across the corner of every image. Password-protected PDFs need unlocking first — the Unlock PDF tool on this site does that locally too.
