What Requires Your Focus?
Before proceeding with merging PNG files into one PDF on Mac, there are a few key factors to consider:
1. Image quality: Pay attention to the image quality of your PNG files. If the images are low resolution or have a small size, merging them into a PDF may result in a lower quality output. Consider optimizing your PNG files before merging, especially if you plan to print or share the PDF.

This may impact storage requirements, file transfer speeds, or compatibility with certain devices or platforms. It is recommended to compress or optimize the PDF file after merging if file size is a concern.
3. Order of images: Make sure you have the PNG files in the desired order before merging them into a PDF. Naming the files sequentially (e.g., image1.png, image2.png, image3.png) can help ensure the correct sequence.
4. Software compatibility: The methods described in this blog post use different software options, some of which may not be compatible with older versions of macOS. Ensure that you have the latest macOS and software versions installed.
