What is a JPG?
JPG is the world’s most popular digital image format and it is a lossy compression system, which basically means the bigger the compression of the file, the smaller the size, but the overall quality of the image will suffer.
On the other hand, if a user chooses a smaller compression rate, the file will be much larger, and the quality will remain amazing.
JPGs compression functions by exploiting the eye’s natural imbalance of differentiating the amount of light that an image has, and our perception of color differences. The eye can detect the subtle changes in lighting conditions far better than the changes in color (this is why we almost see completely black and white in poor light conditions). JPG focuses its compression on the color-part of data, and leaves the lighting part intact.
Difference between JPEG and PDF
PDF files can combine text, bitmaps and vector images whereas JPEG files are actual bitmap images. JPEG file doesn’t look good if you scale it to be bigger than its normal size. On the other hand, PDF files contain text that is scalable and it won’t be blocky when you scale it. If a PDF file contains vector images, you can scale it without any problems. PDF files can include embedded fonts, whereas JPEG files cannot.
How to reduce the file size of JPEG
You can use different image compression programs to shrink the size of your image file. But if you are already learning how to convert PDF to JPEG, you can use the same PDF to JPG converter to reduce the file size of your JPEG.
Start PDF Converter Elite and open a PDF. Click on the Edit menu and then the Resize Pages button. Change the size of your PDF and then convert it to JPEG.
Below you can find more information on how to convert PDF to JPEG with PDF Converter Elite and how to resize pages.
Why are PDFs converted to JPG?
PDFs are mostly converted to JPG for extraction of images from PDF files that usually contain parts that are visual in nature (like pictures, images, graphs), and other textual parts.
So if we want to isolate the pictures from the text, we’ll use PDF to JPG conversion.
If we require to edit the image that’s inside of a PDF file in any way imaginable, we firstly have to convert the PDF to JPG.
This is because the PDF has a read-only nature, which doesn’t allow any kind of editing prior to the conversion, which returns the file into a perfectly editable native state.
3. Decrease the size of a PDF
PDF files are bigger than JPEG files in general. So, if you want to decrease the file size of your PDF document, use PDF to JPG converter. Your computer or usb will now have more space.
