About

What this site is

NetworksInsights collects small, single-purpose tools in one place: converting, compressing, calculating and creating things without having to install anything. The tools are grouped into categories, and the collection grows over time.

• Free. Every tool is free to use.
• No sign-up. There are no accounts.
• Fast.Pages are plain, static and light, so they load quickly even on a slow connection.

How your files are processed

Every tool page says where that tool does its work, in its Quick facts. Today no tool sends your files or your text to a server: the work happens in your browser, on your device. Light tools run on the page itself. Heavier ones, such as the PDF, image, video and audio tools, run in a background worker inside your browser, so the page stays responsive while they work.

Some tools first download a larger file from this site: a PDF engine, an image decoder, an audio encoder, a text-recognition language file or an AI model. That is a download only; nothing you enter goes with it. Each AI model is checked against its fixed SHA-256 fingerprint before it is used, and is not used if it does not match.

The site can be installed as an app, and it keeps a copy of the pages you open so that they work without a connection. It never keeps what you type or the files you open in a tool. Theprivacy pagehas the details.

How the tools are built and tested

Every tool follows the same contract: one folder with its logic, its interface, its page text and its tests. The logic is plain code with no access to the network or to the page, so it can be tested on its own, and every tool has unit tests for it. Every tool also has an end-to-end test that uses it in a real browser, in Chromium, Firefox and WebKit.

No change reaches the site until automated checks pass: type checks, the tests, checks on each tool's page text and structure, limits on how much JavaScript a page may load, a Lighthouse speed test of the pages on a mobile profile, and checks on the site's search data, security headers and the licences of the code it uses. The site is deployed only by those checks, never from a personal computer.

Each tool page states the tool's limits. Official figures, such as tax rates and bands, come from a data file that names the official source, the tax year and the date it was read, and the page shows all three.

Where things stand

The site went live in October 2026. It has 100 tools in 11 categories, all free and none needing an account. New tools are added over time, and each one gets its own page that says what it does, how to use it, what its limits are and where it does its work.

Who runs it
