It is better to combine images into PDF format, as you just open a single PDF file whenever you want to scroll through your memories.

Different tools can help you merge photos to a PDF, but some are too expensive to use, while others can damage the quality of your pictures. The best tool that can be used is UPDF.

Launch the UPDF on your device. At the top right side of the screen, you will find a new feature, "Batch Combine", continue and click on it.

Note: You will see the combine feature on your screen if you are using the version higher than 1.4.1 version on Windows or the 1.4.0 version on Mac. If you can't see the "Batch Combine" feature, you will have to update it. UPDF will also send you an update notification if your version is lower.
