Frequently Asked Questions

Common questions about privacy, browser performance, and supported file types.

Yes, 100%. Unlike conventional online converter websites that upload your files to remote servers, The Ai Toolz runs entirely inside your web browser. Files are read into local memory and processed using WebAssembly and client-side JavaScript. Not a single byte of your documents is ever transmitted across the internet.
No account, email, or registration is required. All 168+ tools are immediately available and completely free to use.
Because processing happens on your computer rather than our servers, there are no artificial file size ceilings imposed by us. You can process large files as long as your device has sufficient RAM available.
Yes! Once a tool page and its local script dependencies are loaded in your browser, the service worker caches the assets. You can continue merging PDFs, calculating statistics, or formatting code even if your internet connection disconnects.
Absolutely. Our tools are fully responsive, touch-friendly, and optimized for mobile browsers including iOS Safari, Chrome, Samsung Internet, and Firefox for Android.
Our compression engine uses local WebAssembly to parse the PDF object tree, strip redundant font descriptors, optimize embedded image streams, and recompress content streams using deflate algorithms directly within your browser.
Yes. Under regulations like GDPR, CCPA, and HIPAA, transmitting personally identifiable information or protected health information to a third-party server creates compliance risks. Because The Ai Toolz never receives or transmits your data, you never transfer custody of your files to any external entity.
Traditional conversion services incur massive monthly cloud server bills because their servers perform all the heavy computation. By leveraging modern client-side browser engines to do the processing on your device, our hosting overhead is virtually zero, allowing us to keep all tools completely free.
