How to reduce PDF file size without having to compress a PDF document?

If you’re working on or creating documents that you plan to save as a PDF and don’t want to or cannot compress PDFs, consider what elements may cause a large PDF file size. The majority of the time, a large PDF file size is caused by a large number of PDF pages with excessive usage of images that were not properly optimized in or outside of a PDF editor.

Here's how to reduce PDF file size without having to compress PDF files:

Compress images to shrink the PDF file size and save storage space.

When it comes to creating a professional-looking PDF documents, marketing and sales presentations, it’s important to ensure that all of your images are optimized for the best quality while keeping the PDF size in mind.

The last thing you want to happen is to create large PDF files that are too difficult to share via email and take forever to load!

One way to keep the size of a PDF document in check is to use Photoshop or Photopea. Photopea is a free online tool for photo editing. You can access it on a Mac in Safari, Chrome, or Firefox.

With Photopea, you can adjust the resolution, reduce the file size of your images, and other settings to ensure that your images look their best in your PDF documents, marketing and sales presentations. This in turn will reduce file size of your PDF file.

Additionally, Photopea can also be used to edit other properties of your images, such as the colors or contrast.

By optimizing your images with Photopea, you can be sure that your PDF documents, and marketing and sales presentations will look their best and the PDF file size will stay manageable so you won’t have to have to compress PDF files as much.

Remove redundant pages in your PDF documents to reduce the file size.

If possible, try to keep the page count to a minimum in your PDF documents. It will greatly reduce the PDF’s file size. If it is a marketing or a sales presentation, try to keep it under 15 slides. Shorter sales and marketing presentations have much higher engagement based on our internal data.

Split your PDF documents.

To avoid bogging down your team with large PDF files, break them into separate files and only send the relevant parts to those who need them. This will eliminate the need to compress PDF files too much. It will save storage space, and make it easier to share your PDF documents.

A PDF file format has a lot of benefits, but one of its drawbacks is that the PDF’s file size can get out of hand pretty fast if they contain visual data and images. This issue, on the other hand, can be easily addressed by using a PDF compressor to compress PDFs, by optimizing your PDF documents, or by using DeckLinks to share your PDF documents, and marketing and sales presentations.
