How to Convert PDF to Image for Easy Viewing on macOS High Sierra

PDF to Image

There are so many times a full PDF document is not going to work. It might be more than you need, or you might need just a couple images from the PDF file. Maybe you want to embed a PDF into a webpage, or insert the PDF content to a PowerPoint presentation file. Converting your PDF documents into an image format like JPG, PNG or GIF could be the solution you are looking for.

Which Format is the Best for Your Documents?

Image formats have their own pros and cons. Before converting a PDF to an image, let's have a look at what's the difference between the most popular formats and when it's appropriate to use them. JPEG, PNG and GIF are the three most common image formats for the web and computer graphics.


Compared to GIF, JPEG is less grainy. When you save an image in JPEG (.jpg) format, much information will be lost from the original image to keep the image file size small, which means some degree of quality is also lost. Generally, the image compression is not that evident at first glance. Because JPEG is smaller, it takes up less room and requires less time to transfer to a site like Facebook. JPEG is not only a free standard and ubiquitous, but also efficient. The quicker users can find and view images, the more images they will see and share and so the more data points the relationship engine has. The engine needs efficiency and JPEG is efficient. That's why Facebook uses JPEG. So if you have the similar requirement, then just convert your PDF to JPEG format.

Pros of JPEG:
* 24-bit color, with up to 16 million colors
* Rich colors, great for photographs that needs fine attention to color detail
* Most used and most widely accepted image format
* Compatible in most OS (Mac, PC, Linux)

Cons of JPEG:
* They tend to discard a lot of data
* After compression, JPEG tends to create artifacts
* Cannot be animated
* Does not support transparency


Pros of GIF:
* Support transparency
* Do small animation effects
* 'Lossless' quality – they contain the same amount of quality as the original, except of course it now only has 256 colors
* Great for images with limited colors, or with flat regions of color

Cons of GIF:
* Only supports 256 colors
* Sometimes, the file size is larger than PNG


PNG is an image format specially designed for the web. Just like the GIF format, the PNG is saved with 256 colors maximum but it saves the color information more efficiently. It also supports an 8 bit transparency.

Pros of PNG:
* It does not lose quality and detail after image compression
* PNG often creates smaller file sizes than GIF
* Supports transparency better than GIF

Cons of PNG:
* Not good for large images because they tend to generate a very large file, sometimes creating larger files than JPEG.
* Unlike GIF however, it cannot be animated
* Not all web browsers can support PNG
