什么是 viu？

viu is a small but powerful command-line image viewer written in Rust that displays images directly in your terminal. It adapts to your terminal's capabilities, using the best available protocol — from the high-fidelity Kitty and iTerm2 graphics protocols down to Unicode block characters as a universal fallback.

            🚀 Why Latest Versions Matter: viu continuously improves support for new image formats, terminal protocols, and display options. The latest releases include AVIF support, improved Kitty protocol rendering, better GIF animation handling, and performance optimizations for large images.
        

⚡ Key Features of viu

🖼️ Multiple Display Protocols

Supports Kitty terminal graphics protocol, iTerm2 inline images, Sixel graphics, and Unicode block characters — automatically picks the best one for your terminal.

📦 Wide Format Support

Displays PNG, JPEG, GIF, BMP, ICO, TIFF, WebP, AVIF, and many more formats via Rust's image crate.

🎞️ GIF Animation

Plays animated GIFs directly in the terminal, looping through frames at the correct frame rate.

📏 Flexible Sizing

Control width, height, or let viu auto-fit the image to your terminal window. Useful for pipelines and scripting.

🔗 Pipe-Friendly

Reads from stdin or file arguments, making it composable with tools like curl, find, and shell pipelines.

⚡ Fast & Lightweight

Written in Rust — minimal startup time, low memory footprint, and no runtime dependencies beyond the binary.

🖥️ Supported Terminal Protocols

Kitty: Full-resolution pixel-perfect images (kitty, Ghostty, WezTerm)
iTerm2: Inline image protocol (iTerm2, WezTerm, Tabby, VSCode)
Sixel: Compatible with foot, Windows Terminal, and many classic terminals
Unicode blocks: Universal fallback — works in every terminal

viu image.png

# Display multiple images
viu *.jpg

# Display from stdin
curl -sL https://example.com/photo.jpg | viu -

# Display a GIF animation
viu animation.gif
        

Sizing options:

# Set width in terminal columns
viu -w 80 image.png

# Set height in terminal rows
viu -h 24 image.png

# Disable auto-resizing
viu -s image.png
        

Pipeline examples:

# Browse images in a directory
for f in ~/Pictures/*.jpg; do viu -w 40 "$f"; done
