How to Decrease PDF File Size in iPhone (tutorial)

Why It Doesn't Work

• The thumbnail text simply repeats the video title, missing an opportunity to add intrigue.
• The dark iPhone blends into the black background, reducing visual impact and clarity.
• The small PDF icon and file graphic are difficult to see on mobile screens.
• The overall composition feels unbalanced with too much empty space on the right.
• The thumbnail lacks a clear 'before and after' visual to demonstrate the value proposition.
