Edge “Capture full page” screenshot is saved smaller than the page, text gets blurry

When I use Microsoft Edge’s screenshot tool (Ctrl+Shift+S, then Capture full page), the saved image comes out smaller than the page itself, so small text looks soft and hard to read. Capture area on the same page keeps the normal size.

Resetting page zoom with Ctrl+0 before capturing does not change it.

A Microsoft Q&A thread from 2023 describes the same thing, with the full page capture saved at about 94% of the real size, and the only workaround offered is Capture area with manual scrolling. That is not practical for long pages.

Is there a setting or flag that makes Capture full page save at 100%, or is the downscale a fixed limit of the feature?
