Convert PDF Pages to JPG

The everyday reason people need this conversion is that the world's casual channels speak image, not document. Chat apps show a JPG inline but render a PDF as a dead attachment icon; slide software places pictures effortlessly but embeds documents awkwardly; marketplaces, social posts and quick email previews all want something that displays instantly. Turning the relevant page into a JPG moves your content into that faster lane - the recipient sees it without opening anything.

Under the hood, each selected page is rendered by pdf.js - the same engine Firefox uses to display PDFs - executing in your browser tab. Rendering means genuinely drawing the page: fonts are laid out, vector art is painted, embedded images are placed, and the finished canvas is encoded to JPEG. Because your machine does the drawing, a 60-page file converts without any upload wait, and password-free PDFs of any origin work identically.

The DPI setting is the lever that matters, and it maps cleanly onto intent. At 72 DPI an A4 page becomes an image about 595 pixels wide - fine for thumbnails and quick shares, small enough to send anywhere. At 150 DPI you get roughly 1240 pixels of width, the sweet spot for reading on screens and pasting into decks. At 300 DPI the page renders at around 2480 pixels across, matching print resolution, and body text stays crisp under magnification. Higher DPI also means bigger files and more memory per page, so select only the pages you need when working at 300.

Choose JPG over PNG in this direction when pages contain photographs, scans or rich graphics, and when small output matters more than perfect text edges - a JPG page runs a fraction of the equivalent PNG. For pages that are purely sharp text and line work headed into documentation, the PNG variant of this tool is the better instrument.
