sorry that this question remained open here. Today, when you paste an image from the clipboard into PDF24 Creator (Ctrl+V or From Clipboard), the image is added with its full pixel size and stored in the PDF in JPEG format with the highest quality.

If a pasted image is still blurry in the created PDF, so that we can reproduce this, please send us the PDF and the original screenshot with this button:
