Fast File Viewer
ONE VIEWER FOR PDF, TEXT, MARKDOWN AND IMAGES. KEYBOARD FIRST.
Overview
Opening a PDF shouldn't launch a heavy suite. Reading a Markdown file shouldn't show you raw symbols. And checking an image shouldn't need yet another app.
Windows makes you juggle a different viewer for every file type — each with its own toolbars, updates, and waiting time.
Viewing a file should be instant: open, read, done.
Fast File Viewer is one lightweight viewer for PDFs, text files, rendered Markdown and images — driven by a searchable command palette (Ctrl+Shift+P), so your hands never leave the keyboard.
It even plays animated GIFs, remembers your recent documents, and reloads a file automatically when it changes on disk.
Why
Most viewers are built for the mouse: tiny toolbar buttons, nested menus, and dialogs for every small change. Rotating a page or finding a word turns into a click safari.
Fast File Viewer puts every action one keystroke away. Search all text with Ctrl+F, run any command from the palette with Ctrl+Shift+P, rotate, move or delete PDF pages directly — and every change writes a backup first.
The result is simple: documents at typing speed — especially valuable for invoices, scans, notes, and everyday paperwork.
