Convert Multiple Images to Single PDF Offline on Windows 10

If you regularly need to share scanned receipts, signed documents, screenshots, or mobile photos, combining multiple images into a single PDF is one of the easiest ways to keep everything organized. A single PDF is easier to email, upload, archive, and print than sending dozens of individual image files.

Many Windows 10 users expect to find a built-in Convert to PDF option by right-clicking an image, but Windows doesn't provide a simple way to merge multiple JPG or PNG files into one PDF. Fortunately, there are several reliable offline methods that let you complete the task without uploading your files to an online service, helping protect your privacy while working with sensitive documents.

Method 1: Microsoft Print to PDF

Windows 10 includes a virtual printer called Microsoft Print to PDF, making it the easiest solution when you only need to convert a small number of images.

To create a PDF from a single image:

  • Open the image in the Photos app or another image viewer.
  • Press Ctrl + P.
  • Select Microsoft Print to PDF as the printer.
  • Choose a save location and create the PDF.

If you need multiple images in one document using only Windows tools, you can also use Microsoft Word:

  • Create a new document.
  • Insert each image, placing one image on each page if desired.
  • Select File → Save As and choose PDF.

This method requires no additional software and works completely offline. However, arranging large batches of images manually can become time-consuming.

Method 2: img2pdf (Command Line)

For users comfortable with PowerShell or Command Prompt, img2pdf is a lightweight offline utility designed specifically for converting images into PDFs. It supports common formats including JPG, PNG, and TIFF while preserving image quality.

Example commands:

Single image

img2pdf image.jpg -o output.pdf

Multiple images

img2pdf image1.jpg image2.png -o output.pdf

All JPG files

img2pdf *.jpg -o output.pdf

A4 page size

img2pdf image.jpg --pagesize A4 -o output.pdf

One of img2pdf's biggest advantages is that JPEG images are often embedded without unnecessary re-encoding, helping maintain image quality while keeping file sizes efficient. The downside is that command-line tools require familiarity with terminal commands and file paths, making them less suitable for beginners.

Method 3: Bulk Image to PDF Converter

If you frequently convert multiple images into PDFs, a dedicated desktop application provides the fastest and most convenient workflow. Bulk Image to PDF Converter Get from Microsoft Store is designed specifically for batch image-to-PDF conversion while working completely offline.

The basic workflow is straightforward:

  • Install the application.
  • Add your JPG or PNG images.
  • Reorder or remove images as needed.
  • Choose a page layout:
  • Original Size
  • Fit to A4 Page
  • Multiple Images on A4
  • Click Convert to generate a single PDF.

Because all processing happens locally, your files never leave your computer. This makes the application suitable for invoices, contracts, identification documents, school assignments, medical records, and other sensitive files.

The free version supports all page layouts and allows up to 10 images per conversion. The Pro version removes this limitation, making it suitable for larger projects.

Which Method Should You Choose?

The best option depends on how often you convert images into PDFs.

  • Microsoft Print to PDF is ideal for occasional conversions when you don't want to install additional software.
  • img2pdf is best for technical users who prefer scripting, automation, and maximum image quality.
  • Bulk Image to PDF Converter is the most practical choice for regular use thanks to its simple interface, offline processing, image reordering, and flexible page layouts.

Each method creates standard PDF files that can be emailed, uploaded, shared, or printed without requiring an internet connection.

Conclusion

Converting multiple images into a single PDF offline on Windows 10 is easier than many users expect once you know the available tools. Whether you choose Microsoft's built-in PDF printer, the powerful img2pdf command-line utility, or a dedicated desktop application such as Bulk Image to PDF Converter, you can organize multiple images into one professional PDF while keeping your files private.

For occasional use, Windows' built-in features may be sufficient. If image-to-PDF conversion is part of your regular workflow, using a dedicated offline application can save significant time while providing greater flexibility and control.
