PDF Tools is a collection of PDF tools that allow you to perform the most common and useful operations on PDF files. Our tools are unique: they don’t need to transfer your files to a server in order to process them, the operations performed on your files are done locally by the browser itself.

Other online PDF tools typically send your files to a server in order to process them and then the resulting files are downloaded back to your computer. This means that in comparison to other PDF tools our tools are fast, economical on data transfers, and anonymous (your privacy is totally protected since your files are not transferred over the internet).
