The issue you are experiencing with vector logos looking fuzzy or cut off when opened in PowerPoint for Windows may be related to how vector graphics are rendered differently across platforms. PowerPoint for Mac and PowerPoint for Windows may handle vector graphics, such as Scalable Vector Graphics (SVG) or other vector formats, in distinct ways due to differences in rendering engines and support for certain graphic formats.
When vector graphics are converted to raster images during the opening process, this can lead to a loss of quality, especially if the resolution settings differ between the two systems. Additionally, if the logos are not fully supported or if there are compatibility issues with the specific vector format used, this can also result in poor rendering.
To mitigate this issue, consider exporting your vector logos to a high-resolution raster format (like PNG) before inserting them into your PowerPoint slides, or ensure that the logos are in a format that is fully supported by both Mac and Windows versions of PowerPoint.
