A free online tool for almost everything you do

Galaxy of Tools brings the small jobs of everyday life into one fast, tidy place. Merge a PDF for a job application, shrink a photo so it fits an upload limit, work out a loan EMI before visiting the bank, check your BMI, convert centimetres to inches, count the words in an essay or format a messy block of JSON — each tool opens instantly and does one job well.

Tools are grouped into 47 clear sectors, from PDF tools and image tools to finance calculators, unit converters, health calculators and developer tools. Every tool page explains how the tool works, the formula or method behind it, and answers to the questions people ask most, so you can trust the result as well as get it.

Because the work happens on your own device, results appear immediately — there is no upload bar, no waiting in a queue and no copy of your file left behind. That makes Galaxy of Tools a safe choice for contracts, IDs, payslips, medical numbers and anything else you would rather keep to yourself.

Questions people ask about Galaxy of Tools

Are Galaxy of Tools tools really free?

Yes. Every tool on Galaxy of Tools is free to use with no sign-up, no trial period, no usage caps and no watermarks on your files.

Do you upload my files?

No. PDF, image, audio and text tools process your files with JavaScript inside your own browser. The file never travels to our servers, so it stays private even for sensitive documents. A handful of tools that need live data — such as currency rates or your public IP address — fetch only that data, never your files.

Do the tools work on my phone?

Yes. Every page is built mobile-first and works in modern browsers on Android, iPhone, iPad, Windows, macOS, Linux and Chromebooks. Nothing needs to be installed.

How do I find the tool I need?

Type what you want to do in the search box — for example “compress pdf”, “emi calculator” or “cm to inches” — and press Enter. You can also open search from any page with Ctrl + K or the / key, or browse the sectors.

What if the tool I need is missing?

Tell us on the contact page or email hello@galaxyoftools.com. New tools are added every week, and requests from users go to the front of the queue.

Can I save my favourite tools?

Yes. Press “Save” on any tool and it appears under “Your tools” on the home page, together with the tools you used most recently. This list is stored only in your browser.

Every tool you need, in one galaxy.
