Free Browser-Based Tools: No Signup, No Downloads, No Uploads
ClickSolveTools has 327 free tools in 15 categories for the jobs you run into every day. Need to estimate a mortgage payment or see how much extra payments save you? There is a calculator for that. Working with a messy JSON payload, a regex pattern or a SQL query? Paste it in and get clean output. Checking your BMI, merging PDFs, compressing a photo or making an invoice? It is all here, and it all runs in your browser.
How It Works
Each tool is a web page that does its work with JavaScript on your device. When you type numbers, paste text or open a file, it is processed in your browser and is not uploaded to our servers. A few tools that remember your work, such as the notepad, to-do list and timers, save it in your browser's local storage on that device only. We use Google Analytics to count visits only if you allow it in the cookie banner, and our pages load code libraries from outside providers, which see your IP address. Our Privacy Policy explains the details.
Who It's For
Students running quick calculations between classes. Developers who need a JSON formatter, regex tester or hash generator without installing an extension.

Frequently Asked Questions
Are the tools free?
Yes. Every tool is free to use, with no signup and no paid version. We do not show ads at this time.
Are my files uploaded?
No. Tools process what you type and the files you open in your browser, on your device. They are not uploaded to our servers.
Do you use cookies or analytics?
Only if you allow it. Google Analytics sets cookies and records your visits only after you allow analytics in the cookie banner; before that, Google's tag sends only a cookieless page-view signal. A Global Privacy Control signal from your browser counts as a rejection. You can change your choice with Cookie settings at the bottom of every page.
How do you make sure the results are right?
We build calculations on named sources and check new and updated tools against worked examples. Yearly figures such as tax brackets change, so check the year a tool uses against the official source. Our editorial policy has the details.
Do I need to create an account?
No. There is no signup, no login and no email required. Just open a tool and use it.
Can I use these tools on my phone?
