Reflow View
When zooming in on content, the fixed visual layout of PDF documents can make reading difficult, as users often need to scroll horizontally across the full width of the document in addition to scrolling vertically. The text reflow option addresses this by allowing users to magnify text within the limits of the viewport, reducing the need for side-to-side scrolling. Reflow view is significantly more convenient and easier to read, especially at high magnification levels (Acrobat supports zooming up to 6400%).
Before enabling content reflow, the original document’s layout remains fixed, which can pose challenges for users who need to zoom in.

To activate text reflow,
Go to the View tab.Click on Zoom in the View expansion menu. bottom right corner of the screen and click on the Display the Page at 100% Magnification.
In the expansion menu, click More at the bottom to show the full list of options.
Click on Reflow at the bottom of the Zoom expansion menu.
After activating reflow, the document shows as a single column: Although it may not look great when viewed at full width, the real advantage of displaying text in a single column is that it improves the experience when zoomed in, because it eliminates side to side scrolling.
