Frequently asked questions

Is AllDays really free?

Yes. Every browser-based tool on AllDays is free to use with no account, no sign-up, and no trial. The site is supported by ads, not by charging for the tools.

Are my files uploaded to a server?

For the browser-based tools, no. They run entirely in your browser, so the files you choose are processed on your own device and never leave it. A small number of tools that genuinely need a server are clearly marked as server-powered.

Do I need to create an account?

No. There is no login, and the tools do not ask for your email or any personal details. You open a tool and use it.

Does AllDays work offline?

Many of the browser-based tools keep working without a connection once the page has loaded, because the processing happens locally. Tools that rely on a server naturally need you to be online.

Can I use the tools for work or commercial projects?

Yes. There is no restriction on using the outputs — converted files, generated passwords, formatted code, calculations — for personal, educational, or commercial purposes.

Which browser should I use?

Any current version of Chrome, Firefox, Edge, or Safari works. Because the tools use standard web features, keeping your browser up to date gives the most reliable results.
