Frequently asked questions

General

Are ToolCMB tools really free?

Yes. Every tool is free to use with no sign-up, no watermark and no daily limits. The site is supported by non-intrusive ads.

Do I need to install anything?

No installation is required. The tools work in any modern browser on Windows, macOS, Linux, Android and iOS.

Is there a file size limit?

Because processing happens on your device, limits depend on your device memory. Most tools handle files up to several hundred megabytes.

Do the tools work offline?

Once a tool page has loaded, most tools continue to work even if your internet connection drops.

Are my files uploaded to your server?

No. Our tools process files locally in your browser using JavaScript and WebAssembly. Your files never leave your device.

Do you store any personal data?

We do not store your files. We use cookies only for basic analytics and advertising as described in our Privacy Policy.
