Browse All ToolsFrequently Asked Questions
Who founded ToolAdda?
ToolAdda was founded by Subhash Yadav, who runs the site. You can reach Subhash at yadavsubhash0001@gmail.com, on GitHub or on LinkedIn.
Is ToolAdda really free?
Yes! ToolAdda is completely free to use. There are no hidden costs, premium versions, or subscription fees. Our mission is to provide free, useful tools for everyone.
Do you collect my data?
Not the files you work on. Every tool processes them on your own device, so documents, images and text never reach our servers — there is no upload step and no account. The site itself does run Google AdSense and analytics, which set cookies and see your visit; our privacy policy sets out exactly what that covers.
Do I need to create an account?
No account needed! Just visit the website and start using the tools immediately. No registration, no login, no hassle.
Can I use ToolAdda offline?
Ten of them, yes. Flatten PDF, Text to Handwriting, Online Notepad, Minesweeper, Poster Printer, Scientific Calculator, Salary Slip Generator, Rent Receipt Generator, Epoch Converter and the Offline Invoice Generator register a service worker, so they keep working with no connection once you have opened them once, and can be installed as a Progressive Web App. The rest need a connection to load, because they pull their libraries from a CDN — but even those process your files on your device, not ours.
Which browsers are supported?
ToolAdda works on all modern browsers including Chrome, Firefox, Safari, and Edge. Mobile browsers are fully supported too.
Can I suggest new tools?
Absolutely! We love hearing from our users. Visit our Contact page to share your suggestions and feature requests.
Is ToolAdda the same as Tool Adda or Tools Adda?
Yes — same site. ToolAdda is the official spelling, written as one word, but Tool Adda, Tools Adda and ToolsAdda are all common ways of typing it and every one of them means this site at tooladda.online. There is no separate Tools Adda website.
