To merge multiple Google Slides presentations into one, follow these steps:
Step 1: Open Google Slides:
- Head over to slides.google.com, either open an existing presentataion or create one.
Step 2: Create a New Presentation:
- Click the "+ New" button on the left-hand side and select "Google Slides" to create a new blank presentation. This will serve as the container for merging the others.
Step 3: Open the First Presentation to Merge:
- Locate the first presentation you want to merge and open it.
Step 4: Copy All Slides:
- Click on the first slide to select it.
- Scroll to the last slide and, while holding down the "Shift" key (or "Ctrl" key on Windows/Linux) on your keyboard, click the last slide. This will select all the slides in the presentation.

Step 5: Copy the Slides:
- Right-click on any of the selected slides, and from the context menu, choose "Copy."

Step 6: Switch to the New Presentation:
- Go back to the new presentation you created in step 2. If it's still open, you can switch to it by clicking on its tab in your browser.
Step 7: Paste the Slides:
- Right-click on any slide in the new presentation and select "Paste." This will paste all the slides you copied from the first presentation into the new one.

Step 8: Repeat for Additional Presentations:
- To merge more presentations, open each one individually, select all the slides, copy them, switch to the new presentation, and paste them, as outlined in steps 3-7.
Step 9: Customize and Save:
- Customize the merged presentation by adding or editing content, adjusting formatting, and adding transitions if necessary.
- Be sure to save your merged presentation.
Step 10: Rename and Share:
- Rename the merged presentation to something descriptive.
- Share it with others or present it as needed.

By following these steps, you can merge multiple Google Slides presentations into a single cohesive presentation, making it easier to manage and present your content.
