How to Take a Screenshot on Mac
Mac has three built-in keyboard shortcuts for screenshots. Each one captures a different area of the screen.
Full Screen
Press Command + Shift + 3.
The entire screen gets captured and saved as a PNG file on your desktop. If you have multiple monitors, you get one file per display.
Selected Area
Press Command + Shift + 4.
Your cursor turns into a crosshair. Click and drag to select the area you want to capture. Release the mouse button and the screenshot saves to your desktop.
A few tricks while the crosshair is active:
- Hold Space to move the entire selection box without resizing it.
- Hold Shift to lock one dimension (height or width) while resizing.
- Press Escape to cancel.
Single Window
Press Command + Shift + 4, then press Space.
The crosshair turns into a camera icon. Hover over the window you want to capture and click it. The screenshot includes the window's drop shadow by default.
To capture without the shadow, hold Option while you click the window.
The Screenshot Toolbar
Press Command + Shift + 5.
This opens a small toolbar at the bottom of the screen with buttons for full screen capture, window capture, selected area capture, and screen recording. The Options menu in the toolbar lets you pick where to save files, set a timer, and toggle the floating thumbnail preview.
This toolbar was added in macOS Mojave. If you are on an older version, it will not be available.
Copy to Clipboard Instead of Saving
Add Control to any screenshot shortcut:
- Command + Control + Shift + 3 copies the full screen to clipboard.
- Command + Control + Shift + 4 copies a selected area to clipboard.
Then paste with Command + V wherever you need it. No file gets created on disk.
Paste a Screenshot into Google Docs
The fastest way is the clipboard method. Press Command + Control + Shift + 4, select the area you want, then open your Google Doc and press Command + V. The image drops right in at your cursor position.
If you already saved the screenshot as a file, open the Google Doc, go to Insert > Image > Upload from computer, and pick the file from your desktop.
You can also drag the file straight from Finder into the Google Doc. Position your cursor where you want the image first, then drag and drop.
Paste a Screenshot into an Email
Same idea. Copy a screenshot to clipboard with Command + Control + Shift + 4, then click into the body of your email and press Command + V. This works in Gmail, Apple Mail, and Outlook.
If you have the screenshot saved as a file instead, you can drag it from Finder into the email body. In Gmail, you can also click the attachment icon (or the inline image icon at the bottom of the compose window) and select the file.
One thing to know: some email clients compress images. If you need the full-resolution PNG, attach it as a file rather than pasting it inline.
Paste a Screenshot into AI Chat Tools
Most AI chatbots can read images now. You can paste or drag a screenshot directly into the conversation and ask questions about what is on screen. This is useful for troubleshooting errors, understanding unfamiliar interfaces, translating text in images, or getting a second opinion on something visual.
Tools That Accept Images
- ChatGPT (chatgpt.com) accepts PNG, JPEG, and GIF. Paste from clipboard or drag a file into the message box. Free users get limited uploads per day. Plus and Team plans have higher limits.
- Claude (claude.ai) accepts images up to 30MB. You can paste from clipboard, drag files in, or click the attachment button. Works on free and paid tiers.
- Google Gemini (gemini.google.com) accepts image uploads on both free and paid plans. Drag in or use the upload button next to the message box.
- Microsoft Copilot (copilot.microsoft.com) accepts image uploads in the chat. Click the image icon in the message bar or paste from clipboard.
- Grok (x.com/i/grok) on X accepts image uploads in conversation. Use the attachment button to add your screenshot.
The clipboard method works the same way every time. Copy the screenshot with Command + Control + Shift + 4, open the AI tool in your browser, click the message box, and press Command + V.
Example Prompts to Use with Screenshots
The key is to be specific about what you need. Here are prompts you can copy and use alongside a pasted screenshot.
Get Help with an Error Message
What does this error mean? Explain it in plain language and tell me how to fix it.

Tips for Better Results
- Crop your screenshot to just the relevant area. Less noise means more accurate answers.
- If the text in the screenshot is small, capture a smaller area at full resolution rather than scaling down the whole screen.
- Include your question in the same message as the image. Do not send the image first and the question second, or the AI may guess at what you want.
- If the first answer is not helpful, follow up with more context about what you were doing when you took the screenshot.
Where Screenshots Get Saved
By default, screenshots land on your desktop with filenames like Screenshot 2026-02-21 at 10.30.45 AM.png.
To change the save location, open the screenshot toolbar with Command + Shift + 5, click Options, and choose a folder under "Save to." Common choices are Desktop, Documents, or a custom Screenshots folder.
You can also change it from Terminal:
defaults write com.apple.screencapture location ~/Pictures/Screenshots
killall SystemUIServer
Replace ~/Pictures/Screenshots with whatever path you prefer.
Change the File Format
Screenshots save as PNG by default. To switch to JPG (smaller files, no transparency):
defaults write com.apple.screencapture type jpg
killall SystemUIServer
Other supported formats: tiff, gif, pdf, and bmp.
To switch back to PNG:
defaults write com.apple.screencapture type png
killall SystemUIServer
