Rasterization Guide: Converting PDF Vector Pages to JPG Images
Converting a PDF page to a JPG image involves rasterizing vector coordinates and fonts into a grid of pixels. This is useful for sharing pages on image-only platforms or embedding pages as slides.
Understanding PDF Page Rasterization
PDFs are primarily composed of vector instructions. Rasterization translates these instructions onto an HTML5 canvas at a specific resolution (DPI), generating a grid of pixels which is then exported as a compressed JPG image file.
Extracting Embedded Images
PDFs often contain embedded raster images in their resources. Our tool can extract these raw image streams (typically DCTDecode or FlateDecode streams) from the PDF catalog and save them as standalone files without quality loss.
