Ways to Make PDF Files Smaller on Mac

When working with PDF files, it is important to consider the size of your document. Large PDF files can be difficult to upload, share, or send via email. As a result, it is crucial to find ways to make your PDF files smaller. In this section, we’ll discuss some ways to make PDF files smaller on Mac.

1. Reduce PDF File Size through Preview

If you are using a Mac, you can reduce PDF file size through the Preview app. To do this, follow these simple steps:

1. Open the PDF file you want to compress in the Preview app.
2. Click on “File” and select “Export”.
3. Select “Reduce File Size” from the “Quartz Filter” drop-down menu.
4. Click on “Save” to save the compressed file.

Preview lets you choose a variety of export options, making it easy to compress a PDF file to a manageable size.

2. Utilize Third-Party Apps

If Preview does not provide the level of compression you need, consider using third-party apps such as Adobe Acrobat or PDF Squeezer. These apps provide more advanced compression features than Preview and can compress your files further while preserving image quality.

3. Scan at a Lower Resolution

If you are scanning a document, consider scanning it at a lower resolution. This will make the resulting file size smaller, but be sure to keep in mind that lower resolutions may affect image quality.

4. Use a PDF Optimizer

Optimizing your PDF file can be done through a variety of third-party apps. Optimizing compresses your PDF file by removing images and other unnecessary elements. Popular PDF optimizers include PDFsam, Compress PDF, and Soda PDF.

5. Check your Fonts

Fonts can take up a lot of space in PDF files. If you use a font that is not widely available, your PDF may have a larger file size. Try using widely available fonts to reduce the file size.

6. Delete Unneeded Pages

If you have a large PDF file, consider deleting unneeded pages. This will reduce the overall file size considerably. This can be done directly in Preview or other third-party apps.

7. Reduce Image Quality

Images can make file sizes quickly get out of hand. While reducing images’ quality can make the file size more manageable, this option might reduce image quality. However, consider reducing image quality to a minimum threshold to get the best possible balance between image quality and file size.

8. Use Zip Archive

Another alternative to compress PDF files to a smaller size is to use Zip Archive. This option might provide smaller file size than the PDF compression on its own.

9. Upload Files to Cloud Drives

If you have trouble emailing the compressed PDF files, consider uploading files to a cloud drive service, such as Google Drive, Dropbox, or OneDrive. This provides a way to share files to many people.

10. Keep PDF Files Up to Date

PDF files can become cluttered, particularly when you continuously edit and save the files, resulting in an error. Thoroughly reviewing the PDF, cleaning them by removing unnecessary information, and optimizing them regularly will ensure that the files maintain the smallest size. Updating the files this way will also ensure they stay relevant.

In conclusion, making PDF files smaller involves reducing images’ quality, optimizing them using compression tools, deleting redundant pages or elements, using readily available fonts, and third-party software. Any of the above methods may work best, depending on the file size and the driving factors. Additionally, frequently keeping PDF files clean, optimized, and up-to-expectations keeps them, and those receiving them, happy.
