The "Free Tool" Trap
We all do it. You need to merge your bank statement with your tax return, so you search for "Free PDF Merger" and upload your files to the first result. But have you read their Privacy Policy? Many free tools upload your files to a cloud server to process them. While reputable sites delete these files eventually, there is always a window of risk where your sensitive financial data exists on a server you don't control. If that server is hacked, your data is exposed.
The Solution: Client-Side Processing
Think of it this way: Server-side tools are like sending your ingredients to a restaurant to be cooked. Client-side tools are like cooking in your own kitchen. At SutraBase, we use advanced browser technologies like WebAssembly. When you use our PDF Merger or Splitter, we send the "code" to your browser, and your browser does the work. Your PDF file never travels over the internet. It stays in your device's memory (RAM) and is processed instantly. This means you can even turn off your WiFi after the page loads, and the tool will still work!
When to Split and When to Merge?
1.Merging: This is essential for job applications. HR managers hate opening 5 different attachments. Use our tool to combine your Cover Letter, Resume, and Portfolio into a single, professional PDF. 2.Splitting: This is vital for privacy. If you need to share a transaction proof from a 50-page bank statement, don't send the whole document. Use our Splitter to extract just Page 42 and share only what is necessary.
