How to Make PDF Smaller: Simple Solutions for a Common Problem

I. Introduction

PDF (Portable Document Format) files are widely used for sharing and archiving documents because they preserve the layout, fonts, images, and other elements in a platform-independent way. However, large PDF files can be a hassle to upload, download, share, or store, especially when you have limited space or slow internet connection. Fortunately, there are several ways to make PDF smaller without sacrificing quality or functionality. In this article, we will explore some of the most effective solutions for reducing PDF file size, including compression software, online tools, reducing resolution, removing unwanted elements, converting to a different file format, and splitting the PDF. By the end of this article, you will be equipped with the knowledge and skills to optimize your PDF files and save time, space, and bandwidth.

II. Use Compression Software

One of the most popular and efficient ways to make PDF smaller is by using compression software. Compression software works by analyzing the content of the PDF file and removing redundant or unnecessary data while maintaining the quality and integrity of the remaining data. This results in a smaller file size without significant loss of visual or textual information.

There are many compression software options available for both Windows and Mac users, and some of the most reputable ones are:

• Adobe Acrobat Pro DC
• Nitro Pro
• Smallpdf
• PDF Compressor

To use compression software, follow these steps:

1. Download and install the compression software of your choice.
2. Open the PDF file you want to compress using the software.
3. Select the compression settings that suit your needs, such as the level of compression, the resolution, the color scheme, the font embedding, and the image optimization.
4. Save the compressed PDF file with a new name or location.
5. Check the size and quality of the compressed PDF file and compare them with the original PDF file.

By using compression software, you can make PDF smaller by up to 90% while maintaining the same level of readability and usability. However, compression software may not be the best option for files that contain sensitive or confidential information, as some compression algorithms may weaken the encryption and security of the file. Therefore, it is essential to choose a reputable and secure compression software and read the terms and conditions carefully before compressing any PDF file.

III. Use Online Tools

If you do not want to download or install any software on your computer, you can also make PDF smaller using online tools. Online tools are web-based applications that offer similar features to compression software but do not require any installation or payment. Online tools can be accessed from any device with an internet connection, and they usually have a simple and user-friendly interface.

Some of the best online tools for reducing PDF file size are:

• ilovepdf
• PDF2Go
• Online-Convert
• PDF24

To use an online tool, follow these steps:

1. Go to the website of the online tool you want to use.
2. Select the PDF file you want to reduce from your computer or cloud storage.
3. Choose the compression settings that suit your needs, such as the level of compression, the resolution, the color scheme, the font embedding, and the image optimization.
4. Wait for the online tool to compress the PDF file and generate a new download link.
5. Download the compressed PDF file and check its size and quality.

The advantages of using online tools are that they are free, accessible, and convenient. However, there are also some risks and limitations associated with online tools, such as the lack of privacy, the potential for malware or viruses, the file size limit, and the quality loss. Therefore, it is crucial to use reputable and secure online tools and avoid uploading any confidential or sensitive files.

IV. Reduce PDF Resolution

Another way to make PDF smaller is by reducing the resolution of the PDF file. The resolution refers to the density of pixels or dots per inch (dpi) in an image or text. The higher the resolution, the more detailed and sharp the image or text, but also the larger the file size. Therefore, by reducing the resolution, you can significantly reduce the file size of the PDF file without affecting its content or layout.

You can reduce the resolution of the PDF file using your operating system’s built-in tools or the compression software or online tools we mentioned earlier. The following are the steps to reduce the resolution on different operating systems:

Windows

1. Open the PDF file in Adobe Acrobat Reader or another PDF viewer.
2. Click on “File” and “Print” or press “Ctrl+P”.
3. Choose the printer named “Microsoft Print to PDF” or any other virtual printer.
4. Click on “Properties” or “Printer Properties” and select “Advanced” or “Document Options”.
5. Choose a lower resolution or quality, such as 150 dpi or grayscale or lower color depth.
6. Click on “OK”, “Apply”, and “Print”.
7. Save the PDF file with a new name or location.

Mac

1. Open the PDF file in Preview or another PDF viewer.
2. Click on “File” and “Export” or press “Shift+Cmd+S”.
3. Choose the format “PDF” and select “Reduce File Size” or “Quartz Filter” or “ColorSync Utility”.
4. Choose a lower resolution or quality, such as 150 dpi or grayscale or lower color depth.
5. Click on “Save” and wait for the file to be processed.

The pros of reducing PDF resolution are that it is simple, fast, and effective. However, the cons of reducing PDF resolution are that it may reduce the quality and readability of the PDF file, especially if it contains small fonts or images or complex graphics or charts.

V. Remove Unwanted Elements

If your PDF file contains some unwanted elements, such as blank pages, headers, footers, watermarks, annotations, bookmarks, or hyperlinks, you can make PDF smaller by removing them. By removing unwanted elements, you can also improve the readability and usability of the PDF file and make it more professional and polished.

Here are the steps to remove unwanted elements using Adobe Acrobat Pro DC or other PDF editors:

1. Open the PDF file in Adobe Acrobat Pro DC or another PDF editor.
2. Select the unwanted element you want to remove using the corresponding tool or command, such as the “Edit” or “Tools” or “Markup” or “Comment” or “View” tab.
3. Delete the selected element by pressing “Delete” or “Backspace” or using the “eraser” or “cut” tool.
4. Save the PDF file with a new name or location.

The benefits of removing unwanted elements are that it streamlines the PDF file and enhances its quality and aesthetics. However, the drawbacks of removing unwanted elements are that it may require some skills, time, and effort, especially for complex or multi-page PDF files.

VI. Convert to a Different File Format

If you want to make PDF smaller and also have more flexibility and compatibility with other devices or software, you can consider converting the PDF file to a different file format, such as JPEG or PNG. These formats are widely used for images and graphics and can be easily resized, shared, or edited without losing quality or resolution. By converting the PDF file to a different file format, you can also reduce the file size and make it easier to upload or download.

You can convert PDF to JPEG or PNG using Adobe Acrobat Pro DC, Microsoft Word, or online tools such as Smallpdf or ilovepdf. Here are the steps to convert PDF to JPEG or PNG using Adobe Acrobat Pro DC:

1. Open the PDF file in Adobe Acrobat Pro DC.
2. Click on “File” and “Export To” and select “Image” and then “JPEG” or “PNG”.
3. Choose the export settings that suit your needs, such as the resolution, the quality, the color scheme, and the cropping.
4. Click on “Export” and choose the location where you want to save the exported files.

The advantages of converting to a different file format are that it allows you to use the PDF content for other purposes, such as presentations, websites, or social media. However, the disadvantages of converting to a different file format are that it may reduce the quality or readability of the content, especially if it contains text or tables or footnotes.

VII. Split the PDF

If your PDF file is too large to handle or share, you can make PDF smaller by splitting it into smaller chunks based on pages, chapters, or sections. By splitting the PDF, you can also make it more organized and manageable and avoid wasting time and effort on scrolling or navigating through the entire file.

You can split the PDF using Adobe Acrobat Pro DC, PDFsam Basic, or online tools such as ilovepdf or Smallpdf. Here are the steps to split the PDF using Adobe Acrobat Pro DC:

1. Open the PDF file in Adobe Acrobat Pro DC.
2. Click on “View” and “Navigation Panels” and select “Pages”.
3. Select the page or range of pages you want to extract using the corresponding tool or command, such as the “Select” or “Hand” or “Crop” or “Split” tool.
4. Click on “Extract” and choose the location where you want to save the extracted file.

The main benefits of splitting the PDF are that it reduces the file size and makes it easier to search, read, or edit the PDF content. However, the main drawbacks of splitting the PDF are that it may require some planning and organizing to decide on the best splitting strategy and that it may result in multiple files that need to be managed and named properly.
