ToolsHelper (toolshelper.site) is an independent catalog of free browser utilities: device checks, image tools, text helpers, developer utilities and calculators. No sign-up, no install.
The site is built and operated by one developer. There is no separate company page or editorial board — the tool copy, FAQs and calculators are written and maintained here. For questions use the email in the footer.
Most helpers run entirely on your device. A few features need the network on purpose (public IP lookup, fetching a page to extract images). Results of calculations and checks are informational.
The interface is available in English and Russian. Light and dark themes are stored locally in the browser.
If a helper is wrong or unclear, write to maskalenchik1998@gmail.com — that is the contact for the project.
