10 Best PDF compressor [2024]

The best PDF compressors reduce file sizes for archiving or sharing - without documents losing any quality and resolution in the process.

PDF documents tend to be relatively small. They’re designed for sharing across multiple devices and users, after all. But once images and graphics are added, file sizes can grow, taking up too much physical and cloud storage space and making them too big to email. The best way to share these larger files is by compressing them, making them small enough to store and share easily. 

If you need to share or store files, the best PDF editors often include efficient PDF compression tools. To make your documents more manageable, we’ve tested the best PDF compressors online, on mobile, and on desktop. As part of our review process, we’ve explored PDF reducer speeds, platform availability, and pricing, with paid-for and free PDF compressors to suit all users and budgets.

3. PDF Compressor

PDF Compressor is one of the best free online PDF compressors. There’s no software to download, so you can use the platform directly from your web browser. It might not be the most attractive website, but having used the tool for years, we can confidently say it does what it says it does: compress PDFs. 

Although there are no options for optimizing compressed PDFs, we’ve found that compressed PDFs are still of a high quality. However, we’d make sure to check large documents before sending them. It’s also worth mentioning that PDF Compressor converts documents to and from PDF format, which can be a helpful additional feature for businesses. 

The company also claims to delete all uploads and conversations after an hour - a nice touch if you're concerned about your data falling into the wrong hands. 

There’s not much else to say about PDF Compressor. It’s free and it works The only real stopper to the workflow is the platform's file size limits, which we encountered with the 1.5GB document we tried.

4. Wondershare PDFelement

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.
