While writing in Writer, I copy and paste images from ppt to writer in GDI format, and covert the .odt to .docx before sending it to others. The images look perfectly with LibreOffice but on the other side when someone opens the file in Microsoft Word the image quality reduces drastically. How to solve this Issue?
sounds like an issue with word and not LO. The recipents of your documents may wish to look here for a solution.
I checked with other Microsoft Word users, and they faced similar issues.
