reduce PDF size

Let’s say you create an amazing PDF file. Lots of graphics, images and bookmarks to make it more comprehensive and appealing. But there’s one major nag: enormous file size! Luckily, there are plenty of ways to reduce PDF size in order to optimize it for web.

Here are 5 ways to make your PDF smaller:

  • Re-save the PDF to reduce PDF size

We don’t mean that you have to redo it from scratch. A simple, yet handy trick to reduce the size of a PDF file is to strip out unwanted objects, remove tags and compress images. You can do that with any program that has a ‘print to PDF’ option or with the free online software. With most PDF editing tools the file size reduction can be done in just a few easy steps:

  1. Open the PDF file
  2. Choose the Export / Save as dialog
  3. Select the PDF as file type
  4. Compress images and optimize the file for fast web view
  • Compress PDF with Adobe Acrobat or Nitro

Whether you are using Adobe Acrobat or Nitro PDF Professional you can reduce PDF size in a simple yet highly effective way. The “Save” feature is often much faster than the “Save As” simply because any additional changes to the file are appended at the end of the file, without a complete rewrite, so a bulk of info is just adding up. Instead, by using the “Save As” feature you can forget about this and reduce PDF size.
All you have to do is:

  1. Open the PDF editor
  2. In Acrobat go to File Save As
  3. In Nitro PDF Professional go to Nitro PDF Save As
  • Remove unwanted objects from PDF files

There are many features that can help you decrease the size of your PDF files. Some of the best tools are Adobe and Nitro PDF. The size of a PDF file is increased by links, bookmarks, form fields, JavaScript. But this shouldn’t be an issue. Whether you use the Nitro PDF Professional or Adobe just follow the steps bellow:

  1. Open the PDF in the PDF editor
  2. In Nitro PDF Professional: Go to Nitro PDF Button > Prepare > Optimize Document
  3. In Acrobat: Go to Advanced > PDF Optimizer. More details here.
  4. Choose the objects to remove
  5. Press OK to complete
  • Clear unused space – Use the PDF Optimizer

There is unused space on your PDF that you might not be aware of. It’s always better to know what pulls up the size of your file. Getting rid of the unused space is often the easiest way to reduce PDF size. If you are using Adobe:
1. Select Advanced
2. Click on PDF Optimizer
3. Select the Audit Space Usage

  • Colors can be a problem in a file size

If color is not your major concern, don’t let the color scheme interfere with the file size. Use the RGB color space instead of the CMYK and you will see a significant change. You can find it in the options menu bar.

Don’t forget to save the file under the same or a different name after making these changes. Even if you don’t see it, size affects the way the file is viewed and transmitted. Keep it simple and small by using these few tricks to reduce PDF size!
