Steps to resize an image inside the PDF.

Unlike Word documents which are made for text, PDF files are like a blank canvas. You can add, remove, and edit all sorts of file types to create the perfect document for your needs.

With a PDF editor like Adobe Acrobat, you’ll find it easy to resize images inside a PDF. Simply follow the steps below:

  1. On the top toolbar, click Tools > Edit PDF > Edit.
  2. Hover your cursor over the image you want to edit.
  3. Click and drag the corners to resize the image.

If you want to maintain the image’s original aspect ratio during the resize, hold the Shift key as you drag the corners. You can also click the center of the image to move it around the document.

You can rotate, flip, crop, or replace an image by choosing Tools > Edit PDF > Edit. Select your image or images and choose from one of the tools under Objects:

How to change the file size online: Compress PDF tool.

Resizing is more than just changing the dimensions of an image. Sometimes you need to change the entire file size to make it easier to save and share. Luckily, you can easily compress a PDF online in just three steps. From any browser:

  1. Visit the Acrobat online services website.
  2. Upload the file you want to compress.
  3. Download the compressed PDF file.

The file size will be reduced without greatly affecting your image resolution. Now, your image will take up less space, and it’ll be easier to send and share.

You can start your 14-day free trial with Acrobat Pro and use the PDF Optimizer, which provides different settings for reducing the size of PDFs. The PDF’s default settings are usually set up for maximum efficiency by compressing images and removing unnecessary items and embedded fonts. Before choosing to optimize a file, you should audit the file’s space usage. These audit results can give you an idea of where it is best to reduce the file size. You can also decrease the size of your PDF by using the Reduce File Size command.
