Say what you're trying to get done in plain words. It picks the best matches from this library only, and says why.
What makes a tool worth shelving
Everything here is a website that does one job in a browser tab. No installers, no browser extensions, no "download our app to continue". Each tool gets one topic shelf and as many "kind" shelves as fit, so a mortgage calculator is on both Money and Calculators, and an AI cover-letter writer is on both AI writing and AI tools.
A lot of these tools never send your data anywhere: the page's own code does the work on your device. If you want to know which is which, read how browser-based tools work, which includes a one-minute check you can run on any site.
Save the ones you like with the bookmark on each tag. Your saved list lives in this browser only, on the Saved page.
Questions people ask
What are the best free online tools?
The best one is the one that does your exact job without an account or a download. For everyday jobs, start with a PDF merger, an image compressor, a password generator, a unit converter and a device tester. The "Useful websites" page lists 61 picks with the reason each one earns a bookmark.
Where can I find free tools online?
Search this library by the job ("merge pdf", "bmi", "logo"), browse a shelf, or describe your task to the tool finder. Every listing links straight to the tool's own website.
What counts as a free online tool here?
A website that does one job in your browser, such as a calculator, converter, generator or editor, and can be used without paying. Nothing on Tools Lib needs a download or an app install.
Do I need an account to use these tools?
Most need no account at all. The "No sign-up" shelf lists the ones that open straight into the tool.
Are browser-based tools safe for private files?
Many process your file on your own device and never upload it. Our guide shows how to check any tool in about a minute using your browser's Network tab.
What are free online AI tools?
Websites that use a language or image model for part of the job, such as rewriting text, summarising a document, naming a business or generating a logo. The AI tools shelf lists 56 of them; most can be tried without an account.
How is the library organised?
Every tool sits on one topic shelf (money, health, design, developer and so on) and can also appear on "kind" shelves such as AI tools, calculators, PDF tools, image tools, no sign-up and privacy-first.
