Use Adobe Acrobat's Combine Files Tool
You can use the built-in Combine Files feature in Adobe Acrobat to merge multiple selected images into a single PDF document.
Adobe Acrobat provides a straightforward tool specifically designed to merge various file formats, including JPEGs, into a single PDF. You can also reorder the images before finalizing the file.
Launch Adobe Acrobat, navigate to the 'Tools' menu at the top, and click on 'Combine Files'.
Click the 'Add Files' button and select the JPEG images you want to convert from your computer.
Drag and drop the thumbnail previews of your JPEG images to arrange them in the exact order you want them to appear in the PDF.
Click the 'Combine' button in the upper right corner to merge the selected JPEGs into a single PDF file.
If you need to divide the images into two or three separate PDF files, simply select only the JPEGs for the first group, combine and save them, then repeat the process for the remaining groups.

Frequently Asked Questions
Can I rearrange the order of the JPEG files before combining them?
Yes. Most PDF tools, including Adobe Acrobat and WPS Office, provide a preview window where you can drag and drop the image thumbnails into your preferred order before clicking the combine or convert button.
Will the image quality drop when I convert JPEGs to a PDF?
Typically, the image quality is preserved during the conversion process. However, some tools may offer compression settings to reduce the final PDF file size. If you want maximum quality, ensure that no compression or 'lossless' settings are selected.
How do I split a combined PDF into smaller files later?
If you change your mind and need to break apart a PDF, you can use the 'Split PDF' or 'Extract Pages' feature available in tools like Adobe Acrobat or the WPS PDF Editor to divide the document into separate files.
Is there a limit to how many JPEGs I can combine into a single PDF?
While the exact limit depends on the software and your computer's available memory, most modern PDF editors allow you to combine dozens or even hundreds of JPEGs into a single file without issue.
