How to Convert PDF to JP(E)G with High Image Quality

Definitely. But Why? Because images are simple, we can get the information at a short glance; images are fascinating, adding entertaining elements to information obtaining; the most important is, images are web-friendly, especially those JPEG images, they are small in size which makes the circulation on internet easy and smooth.

While, the PDF files, the most frequently used format to save and share information, fill all aspects of our life. But it is not so web-friendly like JPEGs and cannot be previewed easily for a faster information filtering. So, very often, we need to convert our PDFs into JPEG to post online or email, etc.

How Much Do You Know About JPEG?

What is JPEG?
JPEG, abbreviation of Joint Photographic Experts Group, is the most commonly used format among those image formats attributing to its high compatibility on Web. It is often used for colorful photos or images with various blends or gradients.

What is the difference between JPG and JPEG?
You may be also wondering why there is another extension JPG, which is so similar with JPEG. Actually, JPG and JPEG is the same thing. Back to those days Windows still dominates, Windows requires that all the files should come with a three letter file extension, so the Joint Photographic Experts Group, which should be originally abbreviated as "JPEG", was assigned with the extension of  ".jpg". However, there is no such a file extension limitations on Macintosh, Mac users took it as ".jpeg". Now such limitations on file extension disappear in Windows, ".jpeg" is also widely accepted. Both 2 terms ".jpg" ".jpeg", though essentially the same thing, coexist and become the most popular image format.

JPEG VS JPEG 2000
JPEG2000 is the new standard created by Joint Photographic Experts Group in the year of 2000 as the next generation of JPEG, designed to offer better compression performance with improved image quality. However, decades past, JPEG doesn't hit the mainstream as it was expected. The main reason seems to go to its entirely different format based on new code which causes lower compatibility and more memory to process. However, JPEG2000 has its own followers, also got support from many other sites or applications.

Quite easy and convenient, but here are some points that may put you off to utilize Adobe Acrobat:

  • If you have a multi-pages PDF, you have to convert all the pages into individual images, you cannot specify the page or the page range as you want to;
  • You cannot perform batch conversion;
  • The biggest problem is: images become blurring, pixellated problems even loom large when zoom in.

The Real Problem: Resolution Easily Lost When Saving PDF as JPEG/JPG

It seems I am not alone when talking about the problems happen when using Adobe to convert PDF to image formats like JPEG/JPG. I found accompanies from Adobe forums:

Whenever I go to save my PDF file as a JPG/JPEG image file, the color of the file becomes inverted. I've done this before (possibly on an older version of adobe) and I didn't have any problems, but I can't figure out how to avoid this change---samanthamehr

When I export my photoshop file into a pdf or jpeg, the images become blurry and pixelated, does anyone know how to fix this?--- changy421 

How these occur? I put the reasons into following 2 categories:

  • The problem of JPEG itself. JPEG files are very lossy because it applies the lossy compression method by discarding most of the information to make the file size smaller.The image quality of JPEG images will lose each time the image is decompressed and recompressed, that’s why you see the colors go paler, the lines get less defined and the whole picture becomes low in resolution. 
  • You are using an expert tool to perform the conversion. PDF to JPEG, 2 different file format, I have to say, there should be some technical work done to carry out the conversion. Adobe is good at many things, but may not including converting a PDF to JPEG.
