ContextPack is a free, client-side web tool that lets you upload a ZIP archive or a folder, preview and select files/folders in an interactive tree, and generate a single, LLM-ready text block from your selection. All processing is done in your browser—no files are ever uploaded.
- ZIP or Folder Input: Upload a
.ziparchive or select a local folder (including subfolders). - Interactive File Tree: Preview your input as a collapsible tree (powered by jsTree) with tri-state checkboxes for easy selection/deselection of files and folders.
- Selection Statistics: See real-time stats for total files, folders, input size, and your current selection.
- Client-Side Processing: All processing is done in your browser. No files are uploaded to any server.
- Text and Binary Handling: Text files are included as UTF-8. Optionally include binary files (e.g., images) as Base64.
- LLM-Ready Output: Concatenates all selected file contents in a strict, repeatable format for easy LLM prompt use.
- Copy/Download Output: One-click copy or download of the output, with the filename based on your input.
- Responsive UI: Clean, modern, and mobile-friendly interface.
- LLM/AI Prompting: Quickly package your codebase or documentation for use as context in LLMs or AI coding assistants.
- Documentation & Analysis: Generate a single text file for documentation, code review, or text analysis tools.
- Version Comparison: Compare the textual content of different codebase versions easily.
- Privacy & Speed: All processing is done in your browser—no files are uploaded to any server.
