Screenshots serve a practical purpose, capturing digital information for later reference or sharing. However, manchmal ist die Erfassung nicht auf die relevanten Bereiche beschränkt und erfordert eine Feinabstimmung. Wenn Sie ein Mac-Nutzer sind, ist das Zuschneiden von Screenshots ein müheloser Vorgang, der nur wenige Klicks erfordert. In dieser ausführlichen Anleitung werden wir die verschiedenen Methoden erläutern, mit denen Sie Screenshots zuschneiden und Ihre erfassten Bilder präzisieren können.
Die erste Methode ist die Verwendung der nativen Screenshot-Werkzeuge. Drücken Sie nach der Aufnahme eines Screenshots die Tastenkombination Befehlstaste + Umschalttaste + 4, um das Screenshot-Werkzeug aufzurufen. Anschließend können Sie einen Bereich zum Zuschneiden auswählen, indem Sie auf die Schaltfläche “Optionen” klicken und die Option “Auswahl” aktivieren. Ziehen Sie dann den Mauszeiger über den gewünschten Bereich und lassen Sie los, um die Auswahl zu bestätigen. Klicken Sie auf “Fertig”, um den zugeschnittenen Screenshot zu speichern.
Alternativ können Sie auch сторонние Softwareprogramme wie Skitch oder Snagit verwenden. Diese Programme bieten zusätzliche Bearbeitungsfunktionen sowie erweiterte Optionen zum Zuschneiden. Mit Skitch können Sie beispielsweise mehrere Screenshots kombinieren, Anmerkungen hinzufügen und Formen zeichnen. Snagit hingegen bietet eine noch umfassendere Suite an Bearbeitungswerkzeugen, darunter die Möglichkeit, Videos aufzunehmen und GIFs zu erstellen. Unabhängig von der gewählten Methode können Sie mit diesen Techniken Ihre Screenshots präzise zuschneiden und sicherstellen, dass nur die relevanten Informationen erfasst werden.

Troubleshooting Common Cropping Issues
If you encounter any difficulties while cropping screenshots on your Mac, below are some troubleshooting tips that can help resolve common cropping issues:
1. The Screenshot Wasn’t Captured Correctly
Ensure you’re using the correct screenshot method (either the keyboard shortcut or the Preview app). If the screenshot didn’t capture the entire desired area, retake the screenshot.
2. The Cropping Tool Isn’t Appearing
Check if you’re attempting to crop the screenshot directly from the Preview app. The cropping tool may not be available for screenshots opened outside of Preview. Try opening the screenshot in Preview and try cropping again.
3. The Cropping Tool Is Greyed Out
You may have selected a protected screenshot or an image from an external source. Protected screenshots or images with copyright restrictions cannot be cropped. Ensure you have the necessary permissions or convert the image into a compatible format.
4. The Cropped Area Is Off-Center or Uneven
When selecting the cropping area, be precise with your mouse or trackpad. Hold down the Shift key to maintain a square or rectangular aspect ratio. Use the arrow keys to fine-tune the selection.
5. The Cropped Image Is Too Small
Ensure you’re not cropping the screenshot too tightly. Expand the selection area to include the desired content. If you accidentally crop too much, use the Undo command (Command + Z) to revert the changes.
6. The Cropped Image Has a Black Border
This usually occurs when the original screenshot has transparent areas. To remove the black border, open the cropped image in an image editing software and add a white or transparent fill to the background.
7. The Cropped Image Is Not Saved
After cropping the screenshot, remember to save the changes. Use the Save or Export options in the Preview app to specify the file format and location.
8. The Cropped Image Is Not in the Right Format
Some applications may not support certain image formats. Ensure you save the cropped image in a compatible format for your intended use. Common image formats include JPEG, PNG, and GIF.
9. The Cropped Image Appears Blurry
The original screenshot may have been low-resolution or blurry. Avoid cropping significant portions of the image to maintain clarity. If possible, capture a higher-resolution screenshot before cropping.
10. Advanced Cropping Techniques: Using Pixel Dimensions
For precise cropping, consider measuring the desired image dimensions using tools like Preview’s Inspector or third-party image editing software. Enter the exact pixel values in the cropping tool options to crop to the desired size.
| Step | Action |
|---|---|
| 1 | Measure the desired image dimensions. |
| 2 | Open the cropping tool in Preview. |
| 3 | Click on the “Options” button. |
| 4 | Enter the pixel dimensions in the appropriate fields. |
| 5 | Click “Crop”. |
