The difference

Built the opposite way to every other PDF site

This isn't a privacy promise from a marketing team. It's a consequence of how the site works.

Other PDF sites
01You upload your file to their server
02It waits in a queue behind other users
03Their machine opens and reads it
04The result is sent back down to you
05A copy stays on their disk for hours
Plus daily limits, watermarks and an account wall.
