Frequently Asked Questions

Yes, every tool on Toolo is completely free to use. No hidden fees, no premium tiers, no watermarks. We believe essential utilities should be accessible to everyone.

No signup required. Just open a tool and start using it immediately. We don't ask for your email, and we don't track your usage.

Absolutely. Most tools run entirely in your browser—your files and data never leave your device. We don't upload, store, or analyze anything you work with.

Yes, all tools are fully responsive and work on smartphones, tablets, laptops, and desktops. No app installation needed—just open the tool in your browser.

Many of our browser-based tools work offline once loaded. PDF tools, text utilities, and generators don't need a constant connection to function.

We're focused on building the best tools first. Our goal is to create utilities so good that people want to support us. Ads will never compromise the user experience.

Three things: privacy (your data stays local), speed (browser-based processing is instant), and simplicity (no bloat, no upsells, just tools that work). We're building what we wish existed.
