Advanced and simple techniques are included. Are you ready? To commence, let us proceed.

How To Reduce PDF Size? 7 Best Methods

In the following section, we will describe each of the seven methods that can be used to compress a PDF.

  • Choose “Save As” rather than “Save.”
  • Using a specialized PDF editor to export PDF files.
  • Reduce file size by using a PDF compress.
  • Examine the amount of space occupied by your PDF document.
  • Use the sophisticated optimization settings of your PDF editor.
  • In your PDF document, remove any unnecessary objects.
  • Reduce the file size of the images in the PDF.

An unlimited number of these methods may be employed.

1. Use “Save As” Instead Of “Save”

This explains why the ‘Save As’ icon is the initial PDF compression method.

  • Many apps have distinct “Save” and “Save As” options.
  • On your device, they both can create new files. However, “Save As” consistently creates a new file, whereas “Save” applies any modifications you make to the original.
  • Therefore, the original PDF file you created, including its file size, is unaltered. Your editor app appends the modifications to the conclusion of your document when you make changes or add new content to it and click “Save.” No rewriting of the original occurs.
  • Every time you click “Save,” the file size increases.
  • The editor can create a fresh, optimized file by picking “Save As” from the File menu.

2. Export PDFs With PDF Editor

Well, the ability to reduce PDF size in a few simple taps is a feature of all main PDF editors. Describe the process using Adobe Acrobat.

5. Reduce PDF Size With Editor’s Advanced Optimization Settings

Numerous PDF editors offer the ability to configure sophisticated optimization settings in addition to their standard compression capabilities. This includes well-known editors such as Adobe, Foxit, and Nitro.

  • To access these settings in Adobe – First, File ➡ Save As Other ➡ Optimized PDF ➡ Advanced Optimization or Tools ➡ Optimize PDF ➡ Advanced Optimization.
  • To access these settings in Foxit – First, File ➡ PDF Optimizer ➡ Advanced Optimization.
  • To access these settings in Nitro – First, File ➡ Optimize PDF ➡ Custom ➡ Show Details.

Now, you can optimize your PDF file in various ways. These include eradicating embedded fonts, configuring image settings, and eliminating undesirable objects.

6. Remove Unwanted Objects

Specific objects can be eliminated using the extensive optimization settings of each leading PDF editor. For example, when digital distribution of PDFs is the only intention, disable alternate images using Adobe. There are two versions of each image in some PDFs: a low-resolution version for the web and a high-resolution version for printing. Disabling alt images eliminates high-resolution versions. Other objects that can be disabled consist of JavaScript actions, embedded page thumbnails, and form submission-related actions. Every editor approaches PDF optimization differently.

7. Compress Images

It is advisable to develop the practice of compressing images before incorporating them into a document. This process guarantees that the file sizes remain as minimal as possible while maintaining the grade of the images. Multiple images can be compressed simultaneously using an image compression tool such as TinyPNG. Additionally, ensure that images are optimized before exporting from the photo editing software.

It is advisable to retain raw (uncompressed) versions of images as a precautionary measure against image quality degradation during compression or undiscovered issues after uploading. Additionally, remember the simple rule: when creating screenshots or images with text overlays, use PNG; otherwise, use JPEG. Simple: when you save images as JPEGs, the resolution of the images with text decreases. Additionally, you can optimize images using the sophisticated optimization settings of your PDF editor. For various color tones, compression type, compression intensity, and pixels per inch (PPI), Adobe has settings available.
