STDU Viewer
STDU Viewer is a free viewer for multiple file formats. The goal of this software is to replace the multiple document viewers with a single one simple application.

Adobe Reader and STDU Viewer, despite their wildly different upbringings, share a common goal: letting humans squint at digital documents while pretending they actually enjoy it. Both will obediently display PDFs, allow you to search for words you’ll never find and even let you add the occasional annotation—should you feel an overwhelming urge to remind your future self of something incomprehensible. Most importantly, they are free, at least until someone finds a way to monetize the simple act of looking at text.

Adobe Reader, forged in the corporate depths of America back in 1993, is a behemoth that does everything you might possibly want with a PDF, including things you never asked for, like embedding videos and nagging you about updates. It’s resource-hungry, loves the sound of its own permissions dialogs and is aimed at professionals who need to digitally sign their soul away. Its security patches arrive with the frequency of unexpected asteroids, keeping it one step ahead of people who use PDFs for evil.

STDU Viewer, on the other hand, hails from Russia and first appeared in 2008, offering a lightweight, no-nonsense approach to document viewing, ideal for students, researchers and people who just want to read something without launching a space shuttle control panel. It happily handles DjVu, TIFF and comic book files, all while using fewer resources than a well-behaved toaster. Unfortunately, it hasn’t received an update since 2017, meaning it now sits in a quiet corner of cyberspace, awaiting users who appreciate its minimalist charm and don’t mind a little digital dust.
