Add Images to Excel Files in C# and VB.NET

GemBox.Spreadsheet represents images with ExcelPicture and it supports various formats like PNG, JPEG, EXIF, GIF, TIFF, ISO, SVG, EMF, and WMF. You can add or remove images from your Excel file using the ExcelWorksheet.Pictures collection.

In PDF files, the SVG images are rendered as vector graphics, resulting in smaller file size and better quality than bitmap images.

In XLS files, only PNG, JPEG, and EMF images are supported.

The example below shows how you can add images in different formats and also positioning them in various ways.
