Avoid scanning PDFs wherever possible

Scanning PDFs should be avoided whenever possible. This is because scanning documents in PDF format takes up a significant amount of storage space and creates files that could be more easily editable or searchable. Scanned PDFs are essentially an image of a document, making it difficult to extract or edit the content within them. Additionally, when searching for specific information within a scanned PDF, there is no option to use text-based search functions. This can be time-consuming and cumbersome, especially with large PDFs or extensive reviewed document collections. Instead, digital formats such as Word or Google Docs should be used for text-based search functionalities and easy editing. Avoiding the scanning of PDFs and opting for more user-friendly designs will enhance productivity and efficiency, particularly when accessing and working with the content within these documents.

Reduce Size with PDF Editors

PDF documents can often be large and take up significant storage space. Thankfully, PDF editors are available that can help reduce PDF size without losing quality.

One such popular software is Adobe Acrobat. To reduce size with Adobe Acrobat, users can go to the “File” menu, select “Save As Other,” and choose the “Reduced Size PDF” option. It will automatically reduce the file size without affecting the document’s overall look and feel.

By following these instructions for Adobe Acrobat, Foxit Editor, and Nitro, users can efficiently compress the files while maintaining the document’s quality. 

Reduce PDF Size with an Online Compressor

Compressor tools are online services or software programs that are designed to reduce the size of PDF files. These tools help compress large files so they can be easily shared or stored without taking up too much space. There are several compressor tools available in the market that offer different features and functionalities. Some of the popular compressor tools include:

  • iLovePDF is known for its simple interface and easy-to-use features, making it a popular choice among users.
  • PDF24 is another popular compressor tool that offers a range of options for compressing PDF files.
  • On the other hand, Adobe Acrobat is a well-known and widely used software program that allows the compression of PDF files and offers various other features, such as editing, converting files, and digital signing.

These compressor tools make it easier for individuals and businesses to compress the size of files and manage their documents efficiently. 

Compress images

To ensure optimal file sizes without compromising image quality, it’s highly recommended that you compress your images before inserting them into your document. Utilize an image compression tool such as TinyPNG to compress multiple images simultaneously. Additionally, before exporting from your photo editing software, take the time to optimize each image individually. It’s also prudent to retain raw (uncompressed) copies of the photos in case any issues arise during the compression process or if image quality is lost upon uploading.

Remember this essential guideline: when dealing with screenshots or images containing text overlays, opt for PNG format; otherwise, choose JPEG format for other types of visuals. This distinction is because saving text-based images as JPEGs often results in quality degradation.

For further optimization options beyond simple image compression tools like TinyPNG, consider utilizing advanced optimization settings in software such as Adobe Acrobat. These settings include color tone adjustments, compression type selection (e.g., lossless or lossy), intensity level customization, and pixels per inch (PPI) adjustments.

Remove unwanted objects

To remove specific objects in your PDF, take advantage of the advanced optimization settings in all the major PDF editing software we mentioned earlier. If you plan to distribute your PDFs digitally, Adobe is your go-to option for turning off alternate images. Some files contain multiple versions of each image: a low-resolution one for online viewing and a high-resolution one for printing purposes. By turning off alt images, you can eliminate the high-res versions. Additionally, there are other objects that you can injure, such as form submission actions, JavaScript actions, and embedded page thumbnails. Keep in mind that each editor has its unique approach when it comes to optimizing your PDF files.

Use "Save As" instead of "Save."

We can compile a PDF by utilizing the trusty old Save As button. Let me explain why this approach is worth considering. You see, when it comes to saving files in most applications, there’s a distinction between Save and Save As functions. Sure, they both have their merits in creating new files on your device. However, there’s an important nuance: unlike Save, which merely appends any modifications or additions to the original PDF file without altering its size, using Save As generates a completely new file that is clean and optimized for compression purposes.

Alternative to PDF Compression to Avoid Quality Loss

PDF files are commonly used for documents that need to be shared and printed. However, compressing PDFs can sometimes result in a loss of quality. To avoid this, there are alternative methods that can be used. One option is to convert the PDF file into a different format, such as a Word document or an image file. This can be done using online converters or software programs. Another option is to use file compression software that specifically preserves the quality of PDF files. These programs can compress the files without losing the content quality or visual elements. Additionally, adjusting the settings of the PDF file itself, such as reducing the resolution of images or removing unnecessary ingredients, can reduce the file size without sacrificing quality.
