Taking a screenshot captures what's on your screen right now
A screenshot is a picture of whatever you see on your monitor at that moment. You can capture your entire screen, just one window, or a specific area you select. The method depends on what operating system you use — Windows, Mac, or Linux — and what you want to do with the image afterward.
Screenshots are useful for saving information, reporting problems to tech support, sharing something you found online, or keeping a record of something that might change. Once you take the screenshot, the image goes to your clipboard (temporary storage) or directly to a file on your computer, depending on which method you use.
Key Takeaways
- Windows users can press the Print Screen key to copy the entire screen, or Windows Key + Shift + S to select and capture just part of the screen.
- Mac users press Command + Shift + 3 for the full screen or Command + Shift + 4 to select a specific area.
- Most screenshots go to your clipboard first, so you can paste them into an email, document, or image editor.
- Built-in screenshot tools on both Windows and Mac let you annotate (add notes or marks) before saving.
How to take a full-screen screenshot on Windows
The simplest method on Windows is to press the Print Screen key (often labeled PrtScn or PrtSc). This copies your entire screen to the clipboard. You won't see anything happen — no sound, no notification — but the image is now ready to paste.
To paste it, open any image editor (Paint, which comes with Windows, works fine), press Ctrl + V, and the screenshot appears. Then save the file with a name you'll remember. If you want to skip the editor step, you can paste directly into an email, document, or messaging app.
If you want the screenshot to save automatically as a file instead of going to the clipboard, press Windows Key + Print Screen. The image saves to your Pictures folder in a subfolder called Screenshots. You'll see the screen briefly dim when it captures, which confirms it worked.
How to capture part of the screen on Windows
If you only need a portion of your screen, use Windows Key + Shift + S. Your screen will dim and your cursor changes to a crosshair. Click and drag to draw a box around the area you want to capture, then release the mouse.
The screenshot goes to your clipboard. A small notification appears in the bottom right corner with a thumbnail of what you captured. Click that thumbnail to open the Snipping Tool, where you can draw on the image, highlight text, or erase parts before saving. If you don't click the notification, the image stays in your clipboard until you paste it somewhere.
How to take a screenshot on Mac
On a Mac, press Command + Shift + 3 to capture the entire screen. The image saves directly to your desktop as a file named "Screenshot [date] at [time].png". You'll hear a camera shutter sound and see a thumbnail appear briefly in the corner of your screen.
To capture only part of the screen, press Command + Shift + 4. Your cursor becomes a crosshair. Click and drag to select the area you want, then release. The image saves to your desktop the same way.
If you want to capture a single window instead of a freehand area, press Command + Shift + 4, then press the spacebar. Your cursor changes to a camera icon. Click the window you want to capture, and it saves to your desktop.
Using the built-in screenshot tools
Both Windows and Mac have more advanced screenshot tools built in. On Windows, open the Snipping Tool by typing its name into the search box. You can choose to capture a free-form shape, a rectangular area, a window, or the full screen. After you capture, the tool opens automatically so you can annotate (add text, draw, or highlight) before saving.
On Mac, press Command + Shift + 5 to open the screenshot menu. You'll see buttons to capture the full screen, a window, or a selected area. Below those buttons is a toolbar where you can choose where to save the image (desktop, documents, clipboard, or an app), set a timer, or show the mouse pointer in the screenshot.
Both tools let you draw on your screenshot after capturing — useful if you want to circle an error message, highlight important text, or add an arrow pointing to something specific.
Where screenshots go and how to find them
When you press Print Screen on Windows or Command + Shift + 3 on Mac, the image goes somewhere different depending on which keys you pressed. If the screenshot went to your clipboard, you need to paste it into a program before you can save it as a file. If it went directly to a file, check your desktop or your Pictures folder.
On Windows, screenshots taken with Windows Key + Print Screen go to Pictures > Screenshots. On Mac, they go to your desktop by default, though you can change this in the screenshot menu. If you're not sure where a screenshot ended up, search your computer for files created in the last few minutes — most systems let you sort by date modified.
Frequently Asked Questions
Can I take a screenshot of just one window?
Yes. On Windows, use Windows Key + Shift + S and carefully draw around the window. On Mac, press Command + Shift + 4, then press spacebar and click the window. Both methods capture only that window, not the background behind it.
What if my Print Screen key doesn't work?
On some laptops, Print Screen shares a key with another function and requires you to hold Fn (function key) at the same time. Try Fn + Print Screen. If that doesn't work, use the keyboard shortcut for your operating system's built-in tool instead — Windows Key + Shift + S on Windows or Command + Shift + 4 on Mac.
Can I edit a screenshot after I take it?
Yes. On Windows, the Snipping Tool opens automatically after you capture and lets you draw, highlight, or erase. On Mac, click the thumbnail that appears in the corner to open the markup tools. You can also paste any screenshot into Paint, Preview, or another image editor to make changes.
How do I take a screenshot on a Chromebook?
Press Ctrl + Show Windows (the Show Windows key is usually where F5 is on a regular keyboard). To capture part of the screen, press Ctrl + Shift + Show Windows, then drag to select. Screenshots save to your Downloads folder.
What file format are screenshots saved in?
On Mac, screenshots save as PNG files by default. On Windows, they save as PNG if you use the built-in tools. If you paste into Paint and save manually, you can choose PNG, JPG, or other formats. PNG is best for screenshots because it preserves detail without making the file huge.
