Why Is It Important to Resize Images in PDF?

Resizing images in PDF documents is crucial, especially when using lots of pictures in your document. The final size of your document is entirely dependent on what you are inserting into your document. The bigger the size of the images, the heavier your document file will become. 

That will be a problem if your page size limit exceeds 10MB. Just saying, 10MB is too much for a regular PDF page combination with colors and pictures. It's considered suboptimal and can affect document speed.

The above example is just the single one; many similar instances are available that show how important it is to resize images in PDF. Here are some examples of why you need to resize:

  • The image size is so big that it does not fit your page format. Scaling too won't solve your problem here. If you do the scaling, the size of the image will put burdens on your entire document. That's why resize your image according to your PDF page or file requirement and then place it in your document.
  • The other problem with adding a larger image to your document is that it does not fit the print format. That's a big question mark! Let's say you've inserted a horizontal image ratio. After finishing your work, you've decided to make a hard copy of that file. And you are about to print out your document with an A4 margin size (8.27 x 11.69). You'll receive a collapsed paper out of the printer.
  • A too-small size can also be a problem for your documents. You've prepared your document for a small size/dimension, and suddenly, you are asked to present your documents in another size or dimension.

Well, these are the possible reasons or situations you may face while preparing a PDF document. That's why it's always essential to choose the best tools before facing different challenges.
