If you don’t want the PPT document you worked hard to be modified and applied by others at will, you can take the following measures to protect the copyright of your file: 1. **Add watermark**: First add a watermark to the slide. The steps are to click "Insert" - "Text box", enter the watermark content, such as "Kingsoft WPS". Then change the text color to a lighter color, adjust the shape and size, and copy it to each slide. 2. **Save as PDF**: Click the "Output as PDF" button in the menu bar to save the document in PDF format before sending it to others. 3. **Document Encryption**: In order to prevent experienced PDF users from converting PDF back to PPT format through software, documents can be encrypted. Click "File" - "Document Encryption" to choose between account encryption and password encryption. 4. **Password Encryption**: In the "Password Encryption" settings, you can set "Open Permission" and "Edit Permission", set the password respectively and click Apply. 5. **Account Encryption**: Selecting "Account Encryption" means that only authorized WPS accounts can open documents, and can set the permission range of authorized objects, such as reading, editing, printing, saving, etc. The following is the corresponding picture description: - [Picture 1.png](https://font2020.oss-cn-beijing.aliyuncs.com/wps/images/50506acc45b3705adf5c19c1d9db255c.png)- [Picture 2.png](https:/ /font2020.oss-cn-beijing.aliyuncs.com/wps/images/d36b6826d306bd39b89a7dc1931ae6c4.png)-[Picture 3.png](https://font2020.oss-cn-beijing.aliyuncs.com/wps/images/8b9b12272aa65bfbbbd 40348a7c588f7 .png)- [Picture 4.png](https://font2020.oss-cn-beijing.aliyuncs.com/wps/images/fc8b501e5e14a813d7800e7e22f7b120.png)- [Picture 5.png](https://font2020.oss -cn-beijing.aliyuncs.com/wps/images/fc3d6b9dbe7eaccf97853079026ac89a.png)- [Picture 6.png](https://font2020.oss-cn-beijing.aliyuncs.com/wps/images/f567639eaa2db2c6435b5e3af67c8bd9 .png) please Note that the above image links are taken directly from the original article, the actual images may need to be viewed in their respective context for complete information.
