Frequently Asked Questions About ZeroServerTools.org
We believe in full transparency and empowering our users. Here are answers to some of the most common questions we receive about how our tools work, our commitment to privacy, and the technology that powers it all.
Are my files really private?
Absolutely. All file processing happens entirely in your browser using WebAssembly and JavaScript. Your files never leave your device, never touch our servers, and we have zero access to your data. This is fundamentally different from traditional web tools that upload files to the cloud.
Do I need to install anything?
No installation required! ZeroServerTools works directly in modern web browsers (Chrome, Firefox, Safari, Edge). Simply visit the tool you need and start using it immediately. The WebAssembly libraries load automatically from trusted CDNs.
What is WebAssembly?
WebAssembly (WASM) is a modern web standard that allows high-performance code to run in browsers at near-native speeds. It enables complex operations like image conversion, video processing, and OCR to run efficiently without server infrastructure.
Will this work on my phone?
Yes! Our tools are fully responsive and work on smartphones and tablets. Processing power depends on your device\s hardware, but modern mobile devices handle most tasks efficiently. Some intensive operations like 4K video processing may be slower on older phones.
Is there a file size limit?
File size limits depend on your device\s available RAM, not our servers. Most modern devices can handle files up to several hundred megabytes. Very large files (1GB+) may cause performance issues on devices with limited memory.
Can I use these tools offline?
Most tools will work offline after the initial page load, thanks to browser caching. However, tools that rely on external CDN libraries (like Tesseract.js for OCR) require internet connectivity to download the necessary WebAssembly modules on first use.
