How to switch between webcams in MakeupMirrorOnline

To switch webcams, start the camera, then choose the other available camera from your browser or device camera selection if that control is shown. If the wrong camera keeps opening, change site camera permission settings in the browser and try again. After switching, check framing with the grid, then use crop, freeze, or the reference pin as needed.

When switching cameras is useful

Some people keep more than one webcam connected. A laptop may have its built-in camera, plus a USB webcam on a monitor. Phones and tablets may offer front and rear cameras. Changing cameras helps when one view has better angle, distance, or sharpness for eyebrow work, eyeliner checks, hairline cleanup, or a full-face look. Start by turning on the camera. If your browser shows a camera picker, select the one you want. If there is no visible picker, the browser may default to the last approved device. In that case, open browser site settings and change the allowed camera for this site, then reload or reopen the page.

Built-in and external webcams can appear as separate camera choices.
Mobile devices may offer front and rear camera options.
A browser can reopen the last camera it remembers for that site.

How to fix the wrong camera opening

If the page opens a camera you do not want, first confirm the browser had permission to use a camera at all. A blocked permission can stop any switch from working. Use the help button path to reach browser site setting instructions, then allow camera access and pick the device you want where your browser offers that option. System privacy settings can also matter, especially on Windows. If the browser itself is blocked from camera use by the operating system, the page may not show a live image even though the site permission looks allowed. On macOS and Safari, per-site camera choices may also affect what opens first.

Check browser site permissions before reconnecting devices.
On Windows, system camera privacy settings can block the browser.
Safari and Firefox keep their own site permission controls.

Reset your view after a camera change

After a switch, the framing may look different right away. One webcam might be wider, lower, or more zoomed than another. Turn on the grid and recenter your face or target area. If the new camera is farther away, use the 1–3x crop for a closer check. If it is already close, leave crop lower for a cleaner image. Freeze is useful right after a switch because it lets you judge sharpness and angle without constant motion. The timer can help if changing devices moved your setup and you need a moment to sit back down. The reference pin stays useful for matching eye height, lip line, or part placement after you swap sources.

Expect a different field of view after changing cameras.
Use freeze to compare sharpness between webcams.
The pin can mark a repeat point before and after the switch.

What does not carry over outside the current visible tab

If you hide the tab, the camera stops and temporary frames stored in memory are cleared. That can matter if you switch away to pair a webcam, plug in a dock, or check another page. Come back and start the camera again once your device setup is ready. Offline behavior is limited. App files can be cached after a successful earlier visit, but camera use without a connection depends on browser behavior. Do not count on an offline webcam switch working in every browser. If you plan to use the tool somewhere with weak service, test your setup while connected first.

Leaving the tab stops the active camera feed.
Temporary image data in memory is cleared when hidden.
Offline camera switching support depends on the browser.

Start the camera on the mirror page.
Pick the other camera from the browser or device camera selection if available.
If the wrong device still opens, change camera permission settings for the site in your browser.
Reframe with the grid, test freeze, and save a PNG only if you want a still image.

Why can I not switch to my USB webcam?

The browser may not have permission for that device, or the operating system may be blocking camera access for the browser. Check browser site settings and, on Windows, system camera privacy settings.

Will the page keep my camera running if I open another tab?

No. When the tab is hidden, the camera stops and temporary frames in memory are cleared.

Does the site save images automatically when I change cameras?

No. A PNG is created only when you choose to export one.
