Taking a screenshot captures whatever is on your screen and saves it as an image file

A screenshot is a digital photo of your screen. You press a key or use a menu command, and your computer saves an image of everything visible at that moment — the open windows, icons, text, and background. That image lands in a folder on your computer or on your clipboard, ready to paste into an email, document, or messaging app.

The method you use depends on your operating system. Windows, Mac, and Linux each have built-in screenshot tools that require no extra software. Most people use the keyboard shortcut because it is the fastest, but your computer also offers menu-based options if you prefer to choose what part of the screen to capture before you take the shot.

Key Takeaways

  • On Windows, press the Print Screen key to capture the whole screen, or Windows Key + Shift + S to select just the part you want.
  • On Mac, press Command + Shift + 3 for the whole screen, or Command + Shift + 4 to select a portion with your cursor.
  • Screenshots save to your clipboard or a folder on your desktop, depending on your operating system and which method you use.
  • You can paste a screenshot directly into an email, document, or chat message without saving it as a separate file first.

Taking a full-screen screenshot on Windows

Press the Print Screen key (often labeled PrtScn or PrtSc) on your keyboard. This key is usually in the top right area, above the arrow keys. When you press it, your computer captures the entire screen and copies it to the clipboard — you will not see a confirmation message or hear a sound, but the image is now ready to use.

To save the screenshot as a file, open Paint (search for "Paint" in the Windows Start menu), then press Ctrl + V to paste the image. Go to File > Save As, choose a folder and a filename, and click Save. The image will be saved as a .png or .jpg file depending on which format you select.

If you want to capture only part of the screen instead of the whole thing, press Windows Key + Shift + S. Your screen will dim slightly and your cursor will change to a crosshair. Click and drag to draw a rectangle around the area you want to capture, then release. The screenshot is copied to your clipboard and a small notification will appear in the bottom right corner.

Taking a full-screen screenshot on Mac

Press Command + Shift + 3 to capture your entire screen. Your Mac will play a camera shutter sound (unless you have muted the system volume), and the screenshot will save as a file on your desktop with a name like "Screenshot 2024-01-15 at 2.30.45 PM.png".

To capture only part of your screen, press Command + Shift + 4. Your cursor will change to a crosshair. Move it to one corner of the area you want to capture, then click and drag to the opposite corner. When you release, the screenshot saves to your desktop the same way.

If you want to copy a screenshot to your clipboard instead of saving it as a file (so you can paste it directly into an email or document), hold down the Control key while pressing the shortcut. So Command + Control + Shift + 3 copies the full screen to your clipboard, and Command + Control + Shift + 4 lets you select a portion to copy.

Using the built-in screenshot tool on Windows 11

Windows 11 includes a dedicated screenshot app called Snipping Tool. Search for "Snipping Tool" in the Windows Start menu and open it. The app window will appear with buttons for different capture modes: Free-form (draw any shape), Rectangular (drag a box), Window (click a specific window), or Full screen (capture everything).

Choose your mode, then click New. Your screen will dim and you will see instructions for that mode. For example, if you chose Rectangular, you will draw a box around the area you want. Once you release the mouse, the screenshot appears in the Snipping Tool window. From there you can annotate it with a pen or highlighter, crop it, or save it to a file.

Using the built-in screenshot tool on Mac

Mac has a tool called Screenshot that works similarly to Windows Snipping Tool. Press Command + Shift + 5 to open it. A menu bar will appear at the bottom of your screen with five buttons: Capture Entire Screen, Capture Selected Window, Capture Selected Portion, Capture Entire Screen (with Timer), and Capture Selected Portion (with Timer).

Click the button for what you want to capture. If you chose a selection mode, drag to select the area. A thumbnail will appear in the bottom right corner of your screen. Click it to open the screenshot in the Preview app, where you can crop, annotate, or save it. If you do not click the thumbnail within a few seconds, the screenshot automatically saves to your desktop.

Where screenshots are saved and how to find them

On Windows, screenshots taken with Print Screen go to your clipboard only — they do not automatically save as a file. You must paste them into Paint, Word, or another program, then save manually. Screenshots taken with Windows Key + Shift + S also go to the clipboard, but a notification appears in the bottom right corner with a thumbnail. Click that thumbnail to open the Snipping Tool and save the image.

On Mac, screenshots taken with Command + Shift + 3 or Command + Shift + 4 save directly to your desktop as .png files. If you used Control + Command + Shift + 3 or 4, the image goes to your clipboard instead. Screenshots taken with the Screenshot tool (Command + Shift + 5) appear as a thumbnail in the bottom right corner — click it to save, or it will save to your desktop automatically after a few seconds.

To find saved screenshots on Windows, open File Explorer and look in your Pictures folder or on your Desktop. On Mac, look on your Desktop or in your Downloads folder. You can also search by filename — Windows screenshots often start with "Screenshot", and Mac screenshots include the date and time in the filename.

Common mistakes and how to avoid them

The most common mistake is pressing Print Screen and then wondering where the file went. Remember: Print Screen copies to your clipboard, it does not save a file. You must paste it somewhere and save it manually. If you want a file to appear automatically, use Windows Key + Shift + S on Windows or Command + Shift + 3 on Mac instead.

Another mistake is taking a screenshot of the wrong window. Before you press the key, make sure the window or area you want is visible and in focus. If you need to capture a specific window, use Command + Shift + 4 on Mac or the Window mode in Windows Snipping Tool — these let you click the exact window you want, rather than trying to select it by dragging.

A third mistake is forgetting to save the file before closing the program. If you paste a screenshot into Paint or another app and then close the app without saving, the image is lost. Always save your file before you close the window, or use a method that saves automatically (like Command + Shift + 3 on Mac).

Frequently Asked Questions

Can I take a screenshot of just one window instead of the whole screen?

Yes. On Windows, use the Window mode in Snipping Tool — search for "Snipping Tool", open it, click the Window button, then click the window you want to capture. On Mac, press Command + Shift + 4, then press the Space bar, and click the window you want. The screenshot will capture only that window, not the background behind it.

What if I want to edit my screenshot before saving it?

On Windows, paste the screenshot into Paint (search for "Paint" in the Start menu), then use the drawing tools to add lines, text, or shapes before you save. On Mac, click the thumbnail that appears in the bottom right corner after you take the screenshot — this opens Preview, where you can crop, rotate, or draw on the image.

How do I take a screenshot on a laptop keyboard that does not have a Print Screen key?

On most laptops, Print Screen is combined with another key. Look for PrtScn or PrtSc printed on a key, usually in the top right area. You may need to hold the Fn key at the same time. If you cannot find it, use Windows Key + Shift + S instead — this method works on all Windows computers and lets you select the area you want.

Can I take a screenshot of something that is not currently visible on my screen?

No. A screenshot captures only what is visible at the moment you press the key. If you need to capture something that is off-screen, scroll to make it visible first, then take the screenshot. Some programs have their own screenshot or export features that can capture content larger than the screen — check the File or Edit menu of the program you are using.

Why does my screenshot look blurry or low quality?

Screenshots are captured at your screen's native resolution, so the quality depends on your display. If the image looks blurry when you zoom in, your screen resolution may be lower than the image size you are trying to create. For most everyday uses like sharing with a friend or pasting into a document, the default quality is fine. If you need higher quality, check whether the program you are screenshotting has an export or print option that offers better resolution.
