How Developers Can Combine Multiple JPGs Into a PDF — Without Writing Code

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.
