Combining multiple JPG images into a single PDF is a common task for developers building document-processing features. Whether you’re working on a receipt scanner, a homework uploader, or an internal tool for organizing images, the process usually involves three steps:
1. Import the images
Your system needs to load each JPG file, keep the order consistent, and prepare them for insertion into the PDF.
2. Create a new PDF structure
A PDF is essentially a container with multiple pages. Each JPG becomes one page in the final file.
3. Insert each image onto a PDF page
The image must be placed within the PDF’s layout. In many cases this means:
- adjusting the size
- maintaining proportions
- fitting it correctly on the page
The difficulty is that different libraries handle placement, scaling, and formatting differently. Making the PDF look good often requires fine-tuning page sizes, margins, and image resolution. This is why building your own merging logic can become more time-consuming than expected.
For users or teams that don’t need to implement this manually, an online tool provides a much simpler workflow. A practical option is:

It places each JPG on its own PDF page automatically, keeps the layout clean, and produces a ready-to-download file—without any setup or code.
