Open chat settings: Select “Chats” from the menu—here’s where you change how chats look.

WhatsApp web常见问题解答

Question: How do I enable full-screen mode in WhatsApp web on my laptop?

> Enabling full-screen mode in WhatsApp web is straightforward and enhances your chat experience, especially on large desktop screens. First, open WhatsApp web in your preferred browser (Chrome, Firefox, Safari). Once logged in, use the browser’s built-in full-screen shortcut: press F11 on Windows/Linux or Command + Control + F on Mac. This removes all toolbars and makes WhatsApp web fill your entire screen. For a permanent solution, install it as a standalone app: in Chrome, click the three dots at the top right → select “Install WhatsApp Web” → follow prompts. Open the app and click the full-screen icon (square with arrows) to expand it fully. If you face issues, clear your browser’s cache or update it—this fixes most glitches. Ensure your display resolution is correct to avoid black bars. This method works for all modern browsers and is a quick way to get more space for your chats.

Question: Why is WhatsApp web not going into full screen on my browser?

> If WhatsApp web won’t go full screen, there are common fixes to try. First, check if your browser is up to date—outdated versions lack compatibility with modern web features. Go to your browser’s “About” section to update. Second, disable conflicting extensions: ad blockers or privacy tools often block full-screen access. Turn them off one by one to identify the culprit. Third, re-enable full-screen permission: in Chrome, go to Settings → Privacy & Security → Site Settings → Full Screen → allow WhatsApp web. Fourth, clear cache and cookies: temporary files cause glitches—go to your browser’s privacy settings and clear them. Restart your browser and try again. These steps resolve most issues, and you’ll be able to use full-screen mode in no time.

Question: Can I use full-screen mode in WhatsApp web during video calls?

> Yes, full-screen mode in WhatsApp web video calls is possible and makes conversations more immersive. When on a call, look for the full-screen icon (square with arrows) at the bottom right of the call window. Click it to expand the call to your entire desktop. This is great for long calls or focusing on the other person. If the icon isn’t visible, refresh WhatsApp web or update your browser—newer versions have this feature. Ensure a stable internet connection, as full-screen uses more bandwidth. To exit, press F11 (Windows) or Command+Control+F (Mac), or click the exit icon. This feature works on Chrome, Edge, and Firefox, so you can enjoy clear, full-screen video calls with friends or colleagues.
