Why Users Are Leaving PDF24
Dated Interface & Confusing Menus
PDF24's web and desktop tools feature a legacy 2010-era interface with dozens of cluttered sub-menus that make simple tasks tedious.
Desktop App Installation Pushes
Users are constantly steered to download and install a heavy Windows application rather than completing quick tasks in the web browser.
Cloud File Transmission
Online PDF24 tasks transmit your documents to European cloud servers for processing, creating unnecessary latency and data compliance concerns.
