PDF to Images

Converting PDF pages to images is useful for a wide range of tasks: generating preview thumbnails, extracting specific pages for presentations, creating image-based versions of documents for platforms that don't support PDF, or sending specific pages as image attachments.

How PDF.js renders PDFs

This tool uses PDF.js, Mozilla's open-source JavaScript PDF renderer. The same library powers Firefox's built-in PDF viewer. It renders each page as a Canvas element in your browser and exports the canvas as a PNG or JPEG. Your PDF is never uploaded — everything happens locally.

Resolution settings

PDF pages are typically designed for print at 72 DPI (screen) or 300 DPI (print). The tool renders at 150 DPI by default, which gives sharp screen images. For print-quality output, use 300 DPI. For thumbnails, 72 DPI is sufficient.

Page ranges

Specify pages as comma-separated numbers or ranges: `1, 3, 5-8, 10`. This extracts only those pages instead of the entire document. Useful for large PDFs where you only need a few pages.

Batch download

All converted images are packaged into a ZIP file for convenient downloading. The ZIP preserves the page order with filenames like `page-001.jpg`, `page-002.jpg`.
