About ITToolKit

A free collection of browser-based utilities built for IT professionals, network engineers, sysadmins and everyday users who need fast, reliable tools without the sign-up friction.

What is ITToolKit?

ITToolKit is a growing library of free online tools designed to make the everyday work of IT professionals faster and easier. Whether you're calculating subnets, decoding a suspicious PowerShell command, looking up a Windows Event ID, or converting units, ITToolKit has a dedicated tool for the job.

Every tool on this site runs entirely in your browser. No data is transmitted to any server, no account is required, and nothing is stored. You get instant results without any of the friction that comes with most online utilities.

ITToolKit is built and maintained by OnlineComputerTechnician.com, an on-site IT support business based in South East Melbourne operating since 2013. The tools here reflect the real day-to-day needs of working IT technicians.

Why We Built This

Working in IT means constantly switching between tools, a subnet calculator here, a Base64 decoder there, a Windows Event ID reference somewhere else. Most of these tools exist in scattered, ad-heavy websites that are slow, cluttered, or require an account to use.

ITToolKit brings the most useful tools into one clean, fast, browser-based toolkit. Everything is purpose-built with the IT professional in mind, from the networking tools that align with real Cisco and Windows environments, to the security tools that help with malware analysis and Windows Event log investigation.

The site is entirely static, there's no backend, no database, no user accounts. This means it loads fast, works offline once cached, and keeps your data completely private.
