How to Combine Multiple JPG and PNG Images into One PDF
Learn how to combine multiple images into one PDF, reorder pages, choose page size and avoid unnecessary quality loss.
ReFormatic ·
Combining images into a PDF is useful for receipts, scanned paperwork, application documents, phone photos of notes or any image set that needs to be read in a fixed order.
Quick answer
Select all the images, place them in the correct page order, choose an appropriate page size and create one PDF. For document photos, check orientation and aspect ratio before export so pages do not appear sideways or get cropped unexpectedly.
Can JPG and PNG files be combined in the same PDF?
Yes. A PDF can contain pages created from different image formats. You do not need to convert every image to the same format first.
The more important decisions are page order, orientation, page size, image fit and the quality of the source files.
Does creating a PDF delete or change the original images?
It should not when the tool creates a new PDF. Keep the original JPG and PNG files as your source and treat the PDF as the sharing or printing copy.
Should you convert PNG to JPG before creating a PDF?
Usually not. If the PNG contains text, screenshots or flat graphics, converting it to JPG first can add an unnecessary lossy compression step.
Use the highest-quality source you already have and create the PDF directly from it.
How to combine images with ReFormatic

- Choose the page size if needed.
- Create the PDF.
The supported workflow runs on the device, which is useful for receipts, IDs and other files you may not want to upload to a remote conversion service.
How do you prevent images from being cropped?
When the image aspect ratio differs from the PDF page ratio, the converter must either add margins, crop or scale the image. For documents, fitting the entire image is usually safer even if it creates white margins.
Crop unwanted desk or background areas before creating the PDF if you want a cleaner page.
Frequently asked questions
Can I combine 20 or more images into one PDF?
Yes, provided the device and tool can handle the files. For very large image sets, check the final PDF size before emailing it.
Does JPG to PDF make an image sharper?
No. Wrapping an image inside a PDF cannot create detail that was not present in the source image.
Is PDF better than ZIP for sending many images?
PDF is usually better when the recipient should read the images in a fixed sequence. ZIP is better when the recipient needs the individual image files for further editing.
Conclusion
For a clean multi-page document, keep the original images, order them correctly and build the PDF directly. Avoid unnecessary intermediate conversions that can add quality loss without improving the final document.
