How to Convert PDF to PNG on Mac with High Resolution?

Sometimes, we need a couple of images in the PDF document rather than the entire file. Or we just want to convert PDF to PNG, even other image formats for different purposes. However, it is not that easy to convert PDF to PNG on mac, while still preserve the original image resolution.

This article will recommend several online and offline PDF to PNG converters for Mac users, also provides the details about how to convert PDF to PNG or other image formats on mac, like PDF to BMP, PDF to Tiff, PDF to JPG etc. clearly.

Table of Contents:

The Image Formats:PNG/TIFF/JPEG/BMP/GIF

There are 5 commonly used image formats created for different purposes: PNG, TIFF, JPEG, BMP, GIF. They are different from each other and let's find out which type should be used under different occasions.

5 popular image formats

JPEG(Joint Photographic Experts Group)
The most popular image format attributing to its web-friendly file size. This is because JPEG use a lossy compression to save image, that is to say, JPEG discard most of its information to keep the file smaller.

GIF(Graphics Interchange Format)
The most suitable for graphics, diagrams, cartoons and logos with fewer colors. That is why GIF is often used for animation effects. GIF compresses images either reducing its colors or replacing multiple patterns into one. That is to say, no matter how many red colors contained in the image, GIF saves it with only one red color.

PNG(Portable Network Graphics)
Another web-friendly image format with a shinning feature supporting 8 bit transparency. It is a more advanced version of GIF, which can save the color information more efficiently than GIF.

BMP(Bitmap)
The image format created by Microsoft and works as the default format to set a wallpaper in Windows. It is quite rich in color, high in quality, which adversely leads to its large file size. 

TIFF(Tagged Image File Format)
The most widely used industry-standard image format. It is usually uncompressed for further manipulations in extensive photo editing software, which make the file size quite bigger than other formats.

You maybe still confused about the difference between them, here I put these photos in different image formats for you to have a comparative look on them. For the reason when files in their original file size, the difference is not so obvious, so I zoom in 300% for you to have a closer look.
