What a screenshot is useful for
A screenshot is an image of what your screen shows at a particular moment. It can help you show someone an error message, save directions for later, or explain where to find a setting. Unlike a photograph of your device, a screenshot usually produces a clear image without glare.
Before you capture anything, decide what the other person needs to see. A full-screen image may provide helpful context, but it can also include open messages, account names, or other unrelated details. If you only need to show one button or message, you can often capture part of the screen or crop the image afterward.
Take a screenshot on a phone
On many Android phones, press the power and volume-down buttons at the same time, then release them. On iPhones without a Home button, press the side button and volume-up button together. On iPhones with a Home button, press the side or top button and the Home button together. A brief flash, sound, or preview may confirm that the image was captured. Button combinations can vary by device, so check your phone’s screenshot controls if these do not work.
A small preview may appear after you take the screenshot. Tap it if you want to crop the image, draw attention to a detail, or delete it. Otherwise, the image is usually saved in your Photos or Gallery app, often in an album called Screenshots. Some phones also offer a screenshot option in a quick-settings panel or accessibility menu, which may be easier than pressing two buttons together.
If you need to capture a long page, look for an option such as “Capture more” or “Full page” after taking the first screenshot. This feature is not available in every app, and it may save the result differently from a regular image. Open the saved file to make sure it contains the part you need.
Take a screenshot on a computer
On Windows, press Windows key + Shift + S to open a selection tool. Drag to select the area you want. The capture may be copied to your clipboard, ready to paste into a message or document; you can also open the notification that appears to edit or save it. Pressing Print Screen is another common option, though what it does depends on your settings and keyboard.
On a Mac, press Shift + Command + 3 to capture the whole screen, or Shift + Command + 4 to select an area. Screenshots commonly appear on the desktop unless you have chosen another save location. On a Chromebook, press the Screenshot key if your keyboard has one, or use Ctrl + Show windows to capture the full screen. Ctrl + Shift + Show windows opens options for selecting an area. Chromebook captures are commonly saved in Downloads.
If a shortcut seems to do nothing, check your clipboard, desktop, or Downloads folder before trying again. Some keyboards require a Function key for certain shortcuts. You may also find a built-in screenshot app by searching your computer’s apps for “screenshot” or “snipping.”
Share the right image
Find the screenshot and open it before sending it. Check that text is readable and that the image shows the problem or instruction clearly. Crop away empty space if it makes the important detail hard to spot, but leave enough surrounding information for the recipient to understand what they are looking at.
To share from a phone, open the image in Photos or Gallery and choose Share, then select the messaging or email app you want to use. On a computer, you can usually attach the saved image to an email or message. If the screenshot is on your clipboard, you may be able to paste it directly with Ctrl + V on Windows or Chromebook, or Command + V on Mac. Before sending, check both the recipient and the attached image.
Protect private information
Look closely at the entire screenshot, not just the part you meant to capture. It might reveal a password, verification code, address, phone number, private conversation, or browser tab title. Crop out unnecessary areas before sharing. If private text remains in the part you need, use an editing tool that fully covers it, then inspect the saved version. A faint highlight or transparent mark may leave text readable.
Screenshots can also become out of date. If you are sharing instructions, mention that menus may look different on another device or after a software update. For a support request, describe what you were trying to do and what happened alongside the image. Once a screenshot is no longer useful, you can delete it from your device and from any conversation where you have control over it.
