Why We Built SanPDF Pro
In an era where data breaches are common, uploading sensitive PDF documents to remote servers for simple tasks like merging or splitting is a significant security risk. SanPDF Pro was developed to solve this problem by bringing professional-grade document processing directly to your web browser.
Our platform utilizes WebAssembly (WASM) technology, allowing us to run high-performance C++ code inside your browser environment. This means your files are never transmitted to our servers. Whether you are a legal professional handling sensitive contracts or a student managing academic papers, your data remains 100% under your control on your local machine.
Frequently Asked Questions
Is SanPDF Pro safe to use?
Absolutely. Unlike other online tools, SanPDF Pro uses WebAssembly (WASM) to process your files directly on your device. Your sensitive data never leaves your browser, ensuring 100% privacy.
Do I need to pay for any features?
No, all our tools are completely free to use. There are no subscriptions, no hidden fees, and no limits on the number of files you can process.
What is WebAssembly (WASM)?
WebAssembly is a technology that allows us to run high-performance code (like C++) directly in your web browser. This allows us to offer professional-grade PDF editing without needing a server-side backend.
Is there a limit on the file size I can process?
Unlike other platforms, we don't impose artificial file size limits. The only limit is your device's memory (RAM). Most modern computers and smartphones can comfortably process PDF files up to 500MB.
Can I use these tools while offline?
Yes! Once the website is fully loaded in your browser, the processing happens locally. This means you can continue to use the tools even if you lose your internet connection while the tab is open.
Do you store any of my personal data?
No. We do not use cookies to track your documents, and since no files are uploaded to our servers, we have no access to your content. Your privacy is our top priority.
Which browsers are supported?
SanPDF Pro is compatible with all modern web browsers that support WebAssembly, including Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari.
