What screen capture and recording do, and when you need them

Screen capture means taking a still image of what is on your monitor right now. Screen recording means saving video of your screen over time, usually with audio. You use screen capture when you need to show someone a single moment — an error message, a form you filled out, a chart from a report. You use screen recording when you need to show a process — how to navigate a menu, what happens when you click a button, how a bug appears when you follow certain steps.

Both tools are built into Windows and macOS, so you do not need to buy software. The built-in tools work for most everyday tasks: documenting a problem for tech support, creating a quick how-to for a coworker, saving proof that something happened on your screen. If you record video regularly or need to edit what you captured, third-party software gives you more control — but start with what your operating system already has.

Screen recording uses storage space and processing power while it runs. A one-hour video at standard quality can take 1 to 3 gigabytes of disk space depending on your settings. If your computer is already running slowly, recording video in the background will make it slower. Closing other programs before you record helps.

Key Takeaways

  • Windows 10 and 11 include a built-in screen recorder (Xbox Game Bar) and screenshot tool that require no setup or purchase.
  • macOS includes screenshot and recording tools in the Shift-Command-5 menu that save directly to your desktop or clipboard.
  • Recording video uses significant disk space and processor power, so close unnecessary programs before you start.
  • Third-party software like OBS Studio (free) or Camtasia (paid) offers more editing options and better quality if you record regularly.
  • Always check whether you have permission to record before capturing video of someone else's screen or audio.

Taking a screenshot on Windows

The simplest way is to press Print Screen (often labeled PrtScn), which copies your entire screen to the clipboard. Open any image editor — Paint, which comes with Windows, works fine — and paste it there. Then save the file. This method is fastest when you just need to grab something quickly.

For more control, use the Snipping Tool, which comes built into Windows 10 and 11. Press Windows key + Shift + S to open it. Your screen will dim and your cursor will change to a crosshair. Click and drag to select the area you want to capture. The image copies to your clipboard automatically. You can then paste it into an email, document, or image editor. The Snipping Tool also lets you capture a window, a rectangular area, or your entire screen — choose the mode from the toolbar before you select.

If you want to annotate the screenshot right away, the Snipping Tool opens a small editor after you capture. You can draw on the image, add text, or erase parts before you save it.

Taking a screenshot on macOS

Press Shift-Command-5 to open the screenshot menu. You will see options to capture your entire screen, a window, or a selected area. Choose what you want, then click the area of your screen you want to capture. The image saves to your desktop as a PNG file by default, though you can change that in System Preferences.

If you want the image in your clipboard instead of saved to disk, hold Control while you take the screenshot. Then paste it directly into an email or document. You can also press Shift-Command-3 for a full-screen capture or Shift-Command-4 for a selected area — these are faster if you use them often.

Recording your screen on Windows

Windows 10 and 11 include Xbox Game Bar, a built-in recorder that works for any program, not just games. Press Windows key + G to open it. You will see a small menu with a red record button. Click it to start recording. Your screen will show a timer in the corner. Press Windows key + G again to stop.

The recording saves to your Videos folder in a file called "Captures". You can then open it in the Photos app or any video player. Xbox Game Bar records your screen and your microphone audio at the same time if a microphone is connected. If you do not want audio, open the Game Bar settings and turn off the microphone before you record.

Xbox Game Bar works well for short recordings and troubleshooting. If you need to record for longer than 30 minutes or want to edit the video afterward, consider a third-party tool instead — the built-in recorder does not include editing features.

Recording your screen on macOS

Press Shift-Command-5 to open the screenshot menu, then click the "Record" button (it looks like a filled circle). Choose whether you want to record your entire screen or just a selected area. If you select an area, click and drag to choose it, then click the "Record" button that appears. A countdown will show, then recording starts.

Stop recording by clicking the stop button in the menu bar at the top of your screen, or press Control-Command-Escape. The video saves to your desktop as an MOV file. You can open it in QuickTime Player or import it into editing software. Like Windows, macOS records your microphone audio at the same time if one is connected.

When to use third-party recording software

OBS Studio is a free, open-source recording program that works on Windows, macOS, and Linux. It is more complex than the built-in tools but gives you precise control over what you record, audio levels, and video quality. OBS is useful if you record regularly, need to combine multiple sources (your screen plus a webcam, for example), or want to stream live to a platform like Twitch or YouTube.

Camtasia is a paid tool ($99 to $199 depending on the version) that includes both recording and editing in one program. You record your screen, then edit the video, add captions, zoom in on parts, and export it — all without switching to a different program. Camtasia is worth the cost if you create training videos or tutorials regularly.

ScreenFlow (macOS only, $99) and Snagit (Windows and macOS, $60 one-time purchase) are also popular. Both focus on simplicity: they record what you need and get out of the way. Choose based on whether you need editing features and which operating system you use.

Managing file size and storage

A one-hour screen recording at 1080p resolution uses roughly 1 to 3 gigabytes of disk space, depending on how much motion is on your screen and your compression settings. If your screen changes a lot (lots of scrolling, window switching, animations), the file will be larger. If your screen is mostly still, it will be smaller.

Before you record, check how much free space you have. Right-click your drive in File Explorer (Windows) or click your drive in Finder (macOS) and look at the available space. If you have less than 5 gigabytes free and plan to record for more than a few minutes, delete old files or move them to an external drive first.

After you record, video files take up space until you delete them. If you only needed the recording to show someone a problem, delete it once they have seen it. If you want to keep it, move it to an external drive or cloud storage to free up space on your computer.

Frequently Asked Questions

Can I record just one window instead of my whole screen?

Yes. On Windows, use the Snipping Tool for screenshots, or use third-party software like OBS Studio for video recording. On macOS, press Shift-Command-5, then click "Record" and select the window you want. Both built-in tools let you choose what to capture before you start.

How do I record my screen without recording audio?

On Windows, open Xbox Game Bar settings and turn off the microphone before you record. On macOS, the built-in recorder captures audio by default; to avoid it, use third-party software like OBS Studio and disable the audio input. You can also record normally and delete the audio track later in a video editor.

What should I do if my recording is too large to email?

Compress the video using free software like HandBrake, or upload it to a cloud service like Google Drive, OneDrive, or Dropbox and share the link instead. Most email providers limit attachments to 20 to 25 megabytes, but a video file is usually much larger.

Is it legal to record someone else's screen?

Recording someone else's screen without permission is illegal in many places, especially if you capture audio. Always ask before you record a call, meeting, or someone else's computer. Some video conferencing tools like Zoom notify all participants when recording starts, which makes permission clear.

Why is my screen recording choppy or slow?

Recording uses processor power and disk speed. Close other programs, especially web browsers with many tabs open. Lower your recording resolution or frame rate if the software allows it. If your computer is old or has a slow hard drive, recording will always be slower than on newer hardware — this is a limitation of the device, not the software.
