Along with compression service, they also offer PDF merging and resizing options too. In case, if you are looking for a service with multitude of feature, then Docupub is an ideal service for you.

There is also an option to convert compressed PDFs into a compatible form for different Acrobat reader versions. Few other options like removing PDF layers, Page labels, Article threads may give you some respite, but don’t expect them to save huge amount of space.

cvision online


CVision is a pretty basic service and offers no custom options like aforementioned services. It lets you compress, optimize, we-optimize and rastertize your document. The best part about the service is that it supports file size of 100MB which is not present in any of the above services. Of course, it will take a hell lot of time in uploading and compression such large file, but it serves the purpose, anyway. It also allows you to select multiple files for compression. The downside of the service that you need to supply your email address to them to download the processed file. It will automatically add your email address to their subscription service. The only caveat of this service is that it also adds watermark to the compressed PDF file which may not be desirable in most of the conditions.

This is the reason why CVision service is listed at the bottom of the service provider. It has its own advantages and a plethora of disadvantages. They also offer a standalone application for free.


VeryPDF is probably the best tool to compress PDF files online. Alternatively, you can try Docupub as well. They both offer a nice set of options to compress your file according to need. On the other hand if you’re in a rush, then you can try CVision which also offers batch compression option. It has few caveats and advantages over the former services.
