Maintain Confidentiality by Processing PDF Files Locally \u2014 No Server Upload, 100% Client-Side Activities<\/strong><\/h2>\n

This online tool may appear fictional, but it is not. It is a modern-day advanced online application<\/a> to fulfill your PDF requirements while maintaining data privacy. Let\u2019s take a quick overview of what it offers.<\/p>\n

The utility provides a guarantee of 0 bytes of server data storage. When you use this online application, the Softaken website stores nothing from your PDF. Let\u2019s take an example. If the PDF file is 25 MB, the website will store 0 MB\/KB. In other words, it saves nothing in its system. It also means your PDF will not go from your laptop to the website\u2019s computer. Every activity, including splitting, merging, and conversion, takes place in your browser using JavaScript (for example, Chrome, Edge, Firefox, or Safari). In simple words, the PDF remains on your device and is processed inside your browser.<\/p>\n

Another advantage of this online application is that it doesn\u2019t require registration to use it. You simply browse the website and use it directly.<\/p>\n

One more surprising thing is that after the online tool has fully loaded, you can turn off the Wi-Fi and still use it for your required purpose, such as PDF conversion, splitting, or merging.<\/p>\n

Discover How the Tool Will Merge and Compress Sensitive PDF Documents Without Risking Data Privacy<\/strong><\/h2>\n

PDF is used by almost every small and big organization worldwide at some point. It is commonly used for handling business contracts, financial audits, and payroll sheets because of its ability to preserve formatting and support easy sharing. When you use ordinary online PDF tools, there are chances of data leakage. Do you want to take this risk? Of course, not.<\/p>\n

Let\u2019s understand this with an easy example. When you use an ordinary online PDF tool<\/a> for any PDF-related activity, the loaded PDF first leaves your computer through the internet to the website’s server and is processed on the website\u2019s computer. After that, the processed PDF is sent back to you. It means one copy of your private data is with the website. It is dangerous because private data can be leaked.<\/p>\n

However, with this Softaken Online PDF tool, all the activities take place in your local browser.<\/p>\n

How Client-Side Processing Works on Softaken<\/strong><\/h3>\n

If you have made up your mind to give this tool a try, learning how it works on your own system instead of the website\u2019s server is essential.<\/p>\n

The first step is to choose one of the 26 different activities for PDFs, such as merging, splitting, converting, and compressing.<\/p>\n

The next step is to upload the target PDF file to this online tool through the drag-and-drop option or by clicking the Choose File button to locate and upload it.<\/p>\n

Now, the tool performs the selected activity automatically inside your browser instead of on the website\u2019s server. During this process, your browser uses a portion of your computer\u2019s RAM (temporary memory). When you close the browser, this temporary working memory is cleared.<\/p>\n

As soon as the work is finished, download the document to your system instantly.<\/p>\n

Why It is Risky to Use Ordinary Online PDF Tools for Corporate Data<\/strong><\/h3>\n

First, understand this with a simple example.<\/p>\n

Banks often use the PDF file format to manage their clients\u2019 data and other confidential information. They have to strictly follow rules that prohibit them from using external websites to compress, merge, or perform other PDF-related activities. If there is a need to compress a PDF file, what will they do? Instead of using an ordinary online PDF tool, they prefer to use a safe application that doesn\u2019t transfer their data to its server. In this way, the bank\u2019s security rules remain intact.<\/p>\n

Several free online tools monetize their platforms through the way you use their websites, such as featuring ads, offering premium services, and temporarily storing files for processing. They may also track your activities, like how often you use the tool and for what purpose. They may also collect technical information, like your IP address. That is why it can be risky to use ordinary online PDF tools.<\/p>\n
