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).
We develop secure online tools that are cloud-based or that execute locally on your device. Protecting your privacy is one of our main concerns when developing our tools.
Our online tools which execute locally on your device don't need to send your data (your files, your audio or video data, etc.) over the internet. All the work is done locally by the browser itself, making these tools very fast and secure. To achieve this we use HTML5 and WebAssembly, a form of code that is run by the browser itself allowing our tools to execute at near-native speed.
We work hard to make our tools run locally on your device since avoiding sending data over the internet is more secure. Sometimes however this is not optimal or possible for tools which for example require high processing power, display maps aware of your current location, or allow you to share data.
Our cloud-based online tools use HTTPS to encrypt your data sent to and downloaded from our cloud infrastructure, and only you have access to your data (unless you have chosen to share it). This makes our cloud-based tools very secure.
