Everything you need to read code
Why Use Code Viewer?
Syntax Highlighting
Automatic keyword-based highlighting for 15+ languages. Keywords, strings, numbers, comments, and functions are color-coded for readability.
Powerful Search
Find any text in your code with regex support, match count, and next/prev navigation. All matches are highlighted in the editor.
Light & Dark Themes
Switch between a clean light theme and a dark VS Code-inspired theme. Comfortable viewing in any environment.
Fullscreen & Minimap
Go fullscreen for distraction-free reading. The minimap gives a bird's-eye view of your entire file at a glance.
Common Use Cases
Why view code online
Quick Code Review
Quickly review code files sent by teammates or found online without opening an IDE. Syntax highlighting makes it easy to read.
Debug & Inspect
Search for specific patterns, variables, or function calls across a file. Highlight lines of interest to focus your debugging.
Learning & Teaching
View code samples with proper highlighting to study syntax. Great for tutorials, workshops, and code walkthroughs.
View on Any Device
Read code on tablets or phones where IDEs are not available. Responsive design ensures readability on any screen size.
How It Works
Upload or Paste Code
Drag and drop a code file, paste code directly, or load a sample to get started instantly.
Language Auto-Detected
The language is detected from the file extension. You can also override it manually from the dropdown.
Explore Your Code
Browse with line numbers, search for patterns, highlight specific lines, and toggle word wrap.
Copy or Download
Copy the full code or selected lines to clipboard, or download as a file.
Pro Tips for Code Viewing
Use Keyboard Shortcuts
Press Ctrl+F to open search, Ctrl+G for go-to-line, and Escape to close overlays. Shift+click line numbers for range selection.
Try Dark Mode
Dark mode reduces eye strain during long reading sessions. The Catppuccin-inspired palette is easy on the eyes.
Regex Search Tips
Use \bword\b for whole-word matches, .* for wildcards, and [0-9]+ for number patterns. Invalid regex falls back to literal search.
Adjust Font Size
Increase font size for presentations or decrease it to see more code at once. The minimap scales accordingly.
