Converting PDF pages to images is useful for a range of tasks: extracting a cover page for use as a preview image, converting a PDF infographic to a shareable JPG, screenshotting specific pages for documentation or presentations, or extracting product catalogue pages as individual images for e-commerce listings. The Utility Spark PDF to Image Converter renders each PDF page to a JPG or PNG image at your specified resolution (DPI). The conversion uses PDF.js — Mozilla's open-source PDF rendering engine, the same engine that powers Firefox's built-in PDF viewer — entirely within your browser.

Why use our tool?
DPI Control — Screen vs Print Quality
72 DPI for screen/web use (smaller file). 150 DPI for general print. 300 DPI for high-quality print or when text must remain crisp at large sizes. Higher DPI produces larger files but sharper images.
Page Range Selection
Convert all pages, a specific page, or a range of pages (e.g. pages 2–5). This avoids extracting all 50 pages of a document when you only need page 3.
PDF.js — Browser-Native Rendering
Mozilla's PDF.js renders the PDF to canvas elements locally. Your PDF — which may contain confidential contracts, financial statements, or proprietary content — never leaves your browser.
