All-in-one PDF compression

Simple compression

Simple compression

With PDF Smart, there’s no software to install. To reduce the volume of your PDF documents, simply import your files into our module. Once the compression settings have been defined, our online tool reduces the size of your PDF document, without you having to do anything else. Then all you have to do is download your compressed document to recover it.

Customisable

Customisable

By default, our online PDF compression tool reduces the size of your file by 40 to 50%. For very bulky documents, you can opt for even greater compression to reduce the size of your PDF by 70 to 80%. To help you choose, our tool indicates the approximate size your PDF document will be after compression.

Quality retained

Quality retained

Using our compression tool, you can reduce the size of your PDF file yet still retain all of its quality and features. To do so, our module removes the data not required for viewing the file, such as font information and blank spaces in the document. Ideal for compressing PDF files of up to 5 Gb.

Security guaranteed

Security guaranteed

To ensure your data is kept private, PDF Smart uses AES and ARC4 protocols to encrypt your documents. That way, your before-and-after PDF files cannot be viewed by third parties. In addition, we also delete all traces of your PDF documents from our servers once they have been compressed online.
