Frequently asked questions

Yes. Every tool on PureBrowser is free to use, with no account, no trial period, no usage limit, and no credit card. There is no paid tier gating any feature.
Where does my data go when I use a tool?
Nowhere. Every tool runs entirely inside your browser using standard web APIs. Text you paste, images you open, and files you process are handled on your own device and are never uploaded to a server.
Do I need to create an account or install anything?
No. There is no sign-up, no email required, and nothing to download. Open PureBrowser, pick a tool, and use it immediately on desktop, tablet, or phone.
Can I use the tools offline?
Once a tool page has loaded, it keeps working without an internet connection, because all of the processing happens locally in your browser.

Free browser tools. Nothing leaves your device.
