Screenshot of Excel sheet with images

GemBox.Spreadsheet supports all popular image formats like PNG, JPEG, EXIF, GIF, TIFF, ISO, SVG, EMF, and WMF. However, note that only PNG, JPEG, and EMF images are supported in XLS files (old binary format).

In PDF files, the SVG images are rendered as vector graphics, resulting in smaller file sizes and better quality than bitmap images (PNG, JPEG, BMP, etc.).
