Questions, answered
Are my files uploaded anywhere?
No. Every Toolsivo tool runs entirely in your browser using JavaScript, HTML Canvas and Web APIs. Your images, PDFs and text never leave your device.
Is Toolsivo really free?
Yes. All 40+ tools are completely free to use with no sign-up, no hidden limits and no watermarks added to your files.
Which browsers are supported?
Any modern browser — Chrome, Edge, Firefox, Safari and their mobile versions. For the best experience keep your browser up to date.
How accurate are the Indian tax and GST calculators?
They follow the current published slabs and rates (FY 2025-26 for income tax). They’re great for planning, but always confirm final figures with a tax professional.
Can I use Toolsivo offline?
Once a tool page has loaded, most tools keep working without a connection because all the processing happens on your device.
