Common questions
Is my data uploaded to any remote server?
No. Tools that can run client-side process everything locally in your browser — your images, text and passwords are never uploaded anywhere.
Is Toolbantu completely free to use?
Yes. Every tool is free, with no accounts, sign-ups or usage limits.
Does Toolbantu work on mobile devices?
Yes. The whole site is responsive and every tool works on phones, tablets and desktops.
What happens if I lose my internet connection?
Once a tool page has loaded, most tools keep working offline since the processing happens on your device. You can also install Toolbantu from your browser, and pages you have opened before open without a connection.
