What is the Images to PDF Converter?
This tool converts multiple JPG, PNG, WebP, or SVG images into a single, organized PDF document with customizable page sizes, orientation, and margins directly in your browser.
Image Dimension Normalization and PDF XObject Embedding
The engine decodes image metadata to extract natural pixel dimensions and color profiles. It calculates scaling factors based on 72 points per inch (DPI/PPI normalization). For fixed page sizes (e.g. A4 at 595.28 x 841.89 points), images are scaled proportionally with letterbox margins to prevent distortion. Each image is embedded directly as a binary PDF image XObject (/Subtype /Image) with appropriate color space flags.
