Why Modern Web Needs Serverless Tools

Traditional online converter websites quietly upload your sensitive PDF contracts, personal photos, and passwords to remote cloud databases. NettTools changes everything.

100% Client-Side Privacy

Every computation is performed strictly inside your browser's local sandbox using JavaScript, WebAssembly, and Web Workers. We have no databases, no tracking cookies, and no cloud file caching.

Instant WebAssembly Speed

Eliminate upload and download queues. Using WebAssembly (Wasm) compiled binaries, tasks run with native hardware performance utilizing your device's multi-core CPU and GPU.

Zero Caps, Completely Free

No credits, no subscription paywalls, and no artificial daily conversion limits. Because computing costs run on your device rather than our servers, NettTools is 100% free forever.

Frequently Asked Questions

Everything you need to know about the NettTools serverless architecture.

Are my confidential documents, CVs, or images uploaded to a server?

No, never. All tools on NettTools run entirely in your local browser sandbox via WebAssembly, Web Workers, and the HTML5 Canvas API. Even if you turn off your Wi-Fi after loading the page, most tools will still function offline!

Who designed and developed NettTools?

NettTools was architected, engineered, and designed by Malsha Vihanga to provide a modern, completely serverless, zero-upload privacy workstation for users worldwide.

Is there any file size limit for PDF, Audio, or Image tools?

Because processing relies on your machine's local RAM rather than a remote server's disk space, you can merge high-resolution PDFs, convert audio containers, or compress large images without encountering arbitrary 10MB or 25MB file upload limits.

Where is the IP Checker located?

The IP & Geolocation Inspector has been integrated into its own dedicated page within the Network & Security category hub, keeping the homepage uncluttered and ultra-fast.

How does NettTools support itself if it's completely free?

Because our architecture does not rely on massive server farms or high-bandwidth cloud video processing, hosting costs for static files are negligible. We are sustained by community sponsorships and non-intrusive sponsorships.
