Compress without limits
with PDF Extra Desktop

PDF Extra Desktop's PDF compressor is designed to optimize PDF documents by making them smaller, faster to load, and easier to work with. It does this by taking your original file and compressing it to only a fraction of the original size in a few easy steps. As a result, the compressed PDFs are faster to share and take up less space on servers, streamlining organizations' work with files and allowing you to focus on more value-producing tasks. As an added bonus, unlike our free online PDF compression tool, you can compress an unlimited amount of files and fine-tune their settings even further!

of embedded images

As images and other graphical elements are added to a PDF, its file size will rapidly grow, making it hard to use and share. With PDF Extra's smart compression tool, you can shrink not just text-based content, but also all embedded images in the file by a custom amount, thereby greatly optimizing the quality of the selected file size. Talk about simplicity!

 

 

 

Why use PDF Extra Desktop instead of your free online tool?


Besides allowing unlimited PDF compression, PDF Extra Desktop lets you work locally on your device, avoiding the need to compress your PDF document online - something which could be problematic if you have no internet service.

With PDF Extra's compression, you also get more granular control and can decide how much to compress images in addition to text-based content, as well as set the appropriate DPI resolution for each object within your document. Finally, by compressing your files, you erase all junk data (unreferenced objects) stored from previous document revisions, ensuring that your final version contains only what truly matters for your project.


FAQs
PDF compression helps you minimize a PDF’s file size as much as possible without degrading its original quality. For instance, it is exceptionally useful when you need to share documents via email since you’re always guaranteed to meet the attachment limits.
When compressing PDF with PDF Extra Desktop, the software allows you to preview the file size of the compressed file and adjust the level of compression until the file size is satisfactory. Previewing is also practical for checking the image quality as PDF compression of images may reduce it.
The PDF Extra Desktop’s compressor balances an optimized file size against the expected quality of images and other file content. If you are not sure what level of compression to use to compress PDF files offline or online, leave it to the PDF compressor and use the default optimized settings.

When choosing this setting, PDF Extra will reduce the size of your PDF files, without compromising on quality. Generally, it’s best to avoid high compression amounts unless absolutely necessary since they could significantly affect the quality of your texts and images and even make them unusable in some extreme cases.
When sending files over email or sharing them with others, it’s essential to enable image compression so that the final result takes up as little space as possible. For your convenience, we suggest making several versions of your file with varying amounts of compression and then picking the file with the smallest size and the best quality.
In order to compress multiple files, you first need to combine the PDFs. You can later compress the combined file to ensure that it will meet any email attachment requirements.
Even if you end up accidentally going overboard with the compression settings, you can rest assured that PDF Extra Desktop will keep your original file intact. This way, you can restart the process as many times as needed until you are fully satisfied with the end result.
There are plenty of online and offline tools that allow you to compress PDFs and make them easier to share in different ways. However, most of these free online compressors do not allow any level of compression customization, which means you don't have any control over the extent to which the file is reduced.

Keep in mind that security is equally important when working with online tools. With offline PDF compressors, such as PDF Extra, you work locally on your desktop and so security is not an issue. With PDF Extra's compression, you can also decide how much reduction you want to apply to the embedded images.
