How the JPG to PDF Converter Works
DocDox JPG to PDF converter combines one or more image files — JPG, PNG, or WebP — into a single PDF document using pdf-lib, processed entirely in your browser. Upload images in any order, rearrange them by dragging, then merge them into a PDF with a single click.
Each image is fitted to a PDF page sized to match the image's own dimensions, so portrait and landscape images each get an appropriately-sized page without any cropping or stretching. Original image quality is maintained because no additional recompression is applied beyond the standard PDF embedding process.
This tool is especially useful for anyone who works with scanned documents: scan pages as individual JPG files from a phone or flatbed scanner, then combine them into a single PDF for filing, sharing, or archiving. There are no file size limits from the server, no account required, and your images stay on your device throughout.
How many images can I combine into one PDF?
There is no fixed limit. Performance depends on your device — dozens of images work well on most modern computers.
Will my images be compressed or resized?
No additional compression is applied. Images are embedded at their original dimensions.
What image formats are supported?
JPG, PNG, and WebP are all supported. HEIC files should first be converted using the HEIC to JPG tool.
