Tips and Tricks
Tip #1: Try Different Compression Levels
Different compression levels may be more appropriate for different types of PDF files. For example, a highly-compressed PDF file may not be suitable for printing, while a low-compressed PDF file may not be suitable for online viewing. Experiment with different compression levels to find the one that best suits your needs.
Tip #2: Combine Compression Methods
You may find that combining different compression methods yields the best results. For example, you could use a web-based tool like SmallPDF in combination with a third-party tool like PDF Compressor to achieve even greater compression.
Tip #3: Keep a Backup Copy
While compressing your PDF files can be a great way to save space and make them easier to share, it’s always wise to keep a backup copy of your original, uncompressed file in case something goes wrong.
Tip #4: Consider File Size Limits
Be aware of any file size limits when sending or uploading your compressed PDF files. For example, many email clients have a maximum file size limit of 25MB, while some websites may have even stricter limits.
Tip #5: Compress Regularly
If you frequently work with PDF files, consider compressing them regularly to free up space on your hard drive and make them easier to manage.
Tip #6: Use OCR
If you’re working with scanned PDF files, consider using OCR (optical character recognition) to convert them to editable text. Not only can this make your PDFs easier to compress, it can also make them more searchable and easier to work with.
Tip #7: Use Preview to Merge PDFs
If you need to combine multiple PDF files, you can use Preview to merge them into a single file. Simply open the first PDF file in Preview, then drag and drop the additional files into the sidebar. You can then rearrange the pages as needed and save your newly-merged PDF.
Tip #8: Use ColorSync Utility to Split PDFs
If you need to split a PDF file into multiple smaller files, you can use ColorSync Utility to accomplish this. Simply open your PDF file in Preview, then click File > Export. In the Export dialog box, select “ColorSync Utility” from the Quartz Filter dropdown list, then choose the “Split PDF” option.
Tip #9: Be Aware of Compression Settings
Be aware of the compression settings when using third-party tools or web-based tools to compress your PDF files. Some tools may reduce the quality of your images or fonts in order to achieve greater compression.
Tip #10: Use PDF Compression as Part of a Larger Workflow
Finally, consider incorporating PDF compression as part of a larger workflow, such as a document management system or automated backup system. By automating the compression process, you can save time and improve efficiency when working with PDF files.
