About the JPG to PDF Converter

Photos, screenshots, and scanned pages are often easier to share when they are packed into one PDF. This converter takes any number of JPG or PNG images, keeps the order you choose, and places each one on its own PDF page. You can let each page fit the image, or standardize everything to A4 or US Letter with a margin, which is useful for printing and formal submissions.

Page size, orientation, and margins

The Fit to image option creates a page whose shape matches the picture. Very large photos are scaled down so the longest page edge stays around 1440 points, which keeps the document practical while preserving the aspect ratio. A4 and US Letter use fixed page dimensions; the image is scaled to fit inside the margins and centered. Auto orientation turns the page landscape when the image is wider than it is tall. Margins are measured in PDF points, where 72 points equal one inch. A margin of 24 points is about 8.5 mm.

Getting the best output

• Use the original files: Re-saving a photo at a smaller size before uploading reduces quality without reducing the final PDF much.
• Keep a consistent order: The table order is the page order. Move images before creating the PDF.
• Choose A4 for documents: Mixed photo sizes look tidy when every page shares the same dimensions.
• Leave a margin for printing: Home printers often cannot print to the edge, so 18-36 points is a safe margin.
• PNG transparency: Transparent areas remain transparent in the PDF; they are not automatically filled with white.
