About JPG to PDF
The JPG to PDF converter is a fast, entirely client-side utility that bundles one or more JPEG images into a single PDF document. By utilizing the pdf-lib library, it creates a new PDF document structure locally in your browser memory and embeds the raw JPEG binary data directly onto the pages. It automatically calculates the optimal page dimensions to fit your images perfectly, preventing unwanted stretching or cropping. Because no server uploads are involved, this tool provides instant conversions regardless of your file size or internet speed, while guaranteeing absolute privacy for your personal photos, scanned receipts, or confidential ID images.
