- Subscription-only - Features focused on professional use Adobe Acrobat is our top choice for best PDF compressor overall. But then, perhaps it is not surprising that the inventors of the PDF would have one of the best PDF compressor software. When we dived into the tool, we were delighted to find a fully-featured PDF editor. Awarding it a rare 5 stars, "sometimes," we wrote in our review, "the best solution on the market has its reputation for a reason." It might be overwhelming (or even overkill) for casual users, but overall, we found Acrobat DC a top choice for serious users needing lots of advanced features. Going beyond simple file compression, Adobe Acrobat features several optimization tools that enable you to control the quality and file size of your PDF compression. A blurry and unreadable PDF is of no use to anyone. With Adobe Acrobat, you can be confident you’ll end up with a high-quality compressed file every time.

- Subscription unlocks extra features - UI can feel disjointed SmallPDF is one of the most popular PDF compressors available, and justifiably so. More than merely a compressing tool, SmallPDF provides a suite of PDF tools that will surpass most businesses’ needs. While reviewing the software, we found it's "great for converting PDFs or for using one tool at a time. However, if you have a lot of different kinds of edits that require different tools, SmallPDF starts to show its weaknesses." Although a 14-day free trial is offered, users will need to pay for a pro subscription if they want to continue using it. With a pro subscription, you will have access not only to online PDF compression, conversion, and merging, but also features such as e-signing, page rotation, and encryption. Premium customers can also download and use SmallPDF's offline PDF compression software. Offline software makes it even more straightforward to compress PDFs. We also like that SmallPDF provides numerous resources for businesses, explaining how the technology works and how you can make the most of it. For businesses, there could be few better choices for PDF compression than SmallPDF. Read our full SmallPDF review (Image credit: Soda PDF)The best free PDF compressor

- No monthly subscriptions, only annual - PDFelement Standard doesn’t include PDF compression PDFelement is another powerful and reliable toolbox for all things PDF. It has an easy to use interface and offers a wide range of features, including uncommon features such as optical character recognition (OCR) conversion and optimization. However, when it comes to PDF compression, we’re a little disappointed. Although Wondershare’s PDF compressor works perfectly, it is only available with PDFelement Pro (the more expensive of Wondershare’s two PDF management products). We would recommend PDFelement to businesses looking to invest in an integrated PDF management solution, as it’s one of the best. But if you’re only compressing PDF files on the odd occasion, then we’d recommend considering one of the cheaper or free PDF compressors. There are also no monthly subscription plans — you'll either have to pay for an annual plan or a bi-annual plan.
