On a shared computer, use Chrome Guest mode if it is available, then use DevTools’ built-in Capture full size screenshot command. Guest mode helps keep browsing activity out of the computer’s Chrome history, but it does not make you anonymous or automatically remove the screenshot file. Handle that file separately.
Capture the entire page in Chrome
- Start a Guest session. In desktop Chrome, open the profile menu and choose Guest or Guest profile. Google recommends Guest mode for public and shared computers. If the computer is managed and Guest mode is unavailable, do not try to bypass its restrictions.
- Open only the page you need. Avoid signing in to sensitive accounts on a computer you do not trust. Google advises users to log in to sensitive websites only on trusted devices.
- Open DevTools for the page. Right-click the webpage and choose Inspect. Keyboard shortcuts vary by operating system and keyboard configuration.
- Open the DevTools Command Menu. Type
screenshotand choose Capture full size screenshot. This captures the page beyond the visible viewport. The separate Capture screenshot command captures only what is currently visible. See Chrome DevTools: Capture screenshots. - Check and handle the resulting file. Find where Chrome saved the screenshot, then move or copy it only to a destination you are authorized to use. Remove the local copy if it should not remain on the shared computer.
- End the Guest session. Close the Guest window or choose the option to exit Guest. Google says Guest browsing activity is deleted from the computer when Guest mode ends.
What Guest mode does—and does not—protect
Google says websites visited in Guest mode do not appear in the browser history, and browsing activity is deleted from the computer when the session ends. That is useful for reducing traces in Chrome on a shared device, but it is not a guarantee that everything created during the session is erased. In particular, do not assume that ending Guest mode securely deletes a screenshot saved as a file.
Guest mode also does not hide activity from websites, signed-in sites, search engines, network operators, employers or schools. Google cautions that device owners may be able to access information such as activity and location even in Guest mode. See Google Chrome Help: Browse Chrome as a guest.
Guest mode or Incognito?
| Question | Guest mode | Incognito |
|---|---|---|
| Google’s guidance for shared or public computers | Google specifically recommends it for using a public computer or sharing a computer. | Google says Incognito can be useful on a shared computer, and separately points users to Guest mode. |
| What happens to Chrome browsing data at the end | Google says Guest browsing activity is deleted from the computer when Guest mode ends. | Chrome removes session site data and the record of visited sites after all Incognito windows close. |
| What can remain on the computer | Do not assume files created or saved in the session are securely erased; Google’s Guest guidance does not promise that. | Downloaded files and saved bookmarks remain after Incognito closes. |
| Who may still see activity | Websites and network operators may see activity; Google also cautions that device owners may access information such as activity and location. | Websites and organizations managing the network, such as employers, schools and ISPs, may observe activity. |
For an unfamiliar shared or public computer, choose Guest mode when available. If it is unavailable and Incognito is permitted, Incognito reduces the local browsing record and site data after every Incognito window is closed, but it does not protect against the device owner, websites or network monitoring. Neither mode is anonymity. See Google Chrome Help: Browse in Incognito mode.

Keep the screenshot separate from the browsing session
A browsing mode and a saved image are different things. A screenshot may remain in a downloads folder or another save location after you exit the session. Google explicitly says Incognito downloads remain on the device after Incognito closes; its Guest guidance does not promise secure deletion of saved files either.
- Save the image only if you are allowed to do so, and send it only to an authorized destination.
- Check the actual save location rather than assuming Chrome used a particular folder.
- Delete any local copy that should not be available to the next user. Do not treat closing Guest or Incognito as proof that the file has been securely erased.
- Avoid capturing sensitive information that is visible on the page, especially if the image will be shared.
If full-page capture is unavailable or fails
- The command is missing: Confirm that DevTools is open for the webpage and search its Command Menu for
screenshot. Make sure you are choosing Capture full size screenshot, not the viewport-only option. - The computer blocks Guest, Incognito or screenshots: An administrator may have configured Chrome’s availability or a screenshot-prevention policy. Follow the organization’s rules or ask its administrator; do not try to bypass controls. See Chrome Enterprise and Education Help: Allow private browsing.
- You are considering a different Chrome profile: Profiles keep bookmarks, history, passwords and settings separate, but they are not a substitute for a private session on an unlocked shared computer. Someone with device access may switch profiles. See Google Chrome Help: Manage Chrome with multiple profiles.
- You cannot find the image: Check Chrome’s download list and the computer’s save location. The capture command does not make a promise that the file is securely removed when the session ends.
Or skip the browser setup
