You can embed graphic files (such as your company’s logo) in your merge templates to improve its appearance.
Please follow these rules when embedding graphics in your templates:
Graphic files must be JPG or PNG files – certain other file types may prevent proper merging of data or may not merge at all
Use the smallest possible file size that will provide adequate resolution.
In Conga® Mail Merge situations, remember that graphics are included on every page, dramatically increasing the file size:
Running a Conga Mail Merge solution to produce 1,000 documents for a template file of 250 KB (including graphics) would result in a total merge output file size of 250 MB.
You can reduce the file size of your graphic images by using a graphics utility program, such as Adobe Photoshop®, Paint.NET®, or Image Resizer (part of the Microsoft PowerToys® collection).
