I need to make a presentation, probably in PDF, of an existing website flow modification.
I took a screenshot of the website, pasted it into figma, and then made some vector changes, so the result is that I have a composite of both the pasted image and new vector additions.
I see the way to export to PDF is by adding frames, but when I export, I see that the pasted image is losing its pixel perfect quality, since figma probably modifies the proportion to fit the frame, and I have no idea what frame size should I choose in order for it not to modify the image.
Any idea, or better idea how to achieve what I need?
