Upload a file, make precise edits, and download a corrected EPUB, no accounts, no background processing, and no files stored on the server.\n\n- Simple install with Docker image available.\n- No configuration necessary\n\n*The project is inspired by [BentoPDF](https://github.com/mgmeyers/bentopdf) in both philosophy and workflow.*\n\n\u003cp\u003e\n  \u003cimg src=\"https://img.shields.io/github/v/release/gjessing1/epub-bookprep\" alt=\"Latest release\"\u003e\n  \u003cimg src=\"https://img.shields.io/github/stars/gjessing1/epub-bookprep?style=social\" alt=\"GitHub stars\"\u003e\n  \u003ca href=\"https://buymeacoffee.com/gjessing\"\u003e\n    \u003cimg src=\"https://cdn.buymeacoffee.com/buttons/v2/default-yellow.png\" width=\"80\" style=\"vertical-align: middle;\"\u003e\n  \u003c/a\u003e\n\u003c/p\u003e\n\n## Live demo (temporary)\nA public demo is available for testing and evaluation:\n\n👉 **[Try the demo](https://gjessing.io/epub/demo/)**\n\nThe demo is intended for light, manual testing only.  \nUploaded files are processed in memory and are not stored, but availability and uptime are not guaranteed.  \nFor regular use, self-hosting via Docker is recommended.\n\n## Features\n- Inspect and edit common EPUB metadata fields  \n  (title, author, language, publisher, series, identifiers, description)\n- Fetch metadata from public sources using ISBN or title-based search\n- Review and selectively apply fetched metadata to avoid incorrect matches\n- Search for available cover images, preview alternatives, and explicitly choose whether to replace or keep the existing cover\n- Clean and normalize metadata:\n  - trim whitespace\n  - normalize date formats\n  - strip HTML from descriptions\n  - deduplicate subjects\n- Preview how metadata will appear in OPDS-based clients before importing into a library or reader\n- EPUB 3 editor with EPUB 2 backward compatability\n- Extremely lightweight: the Docker container uses under 30 MB of host memory, as all processing happens in the browser.\n- Light and dark mode support\n\n## Screenshots (Mobile view)\n\u003cp align=\"left\"\u003e\n  \u003cimg src=\"/examples/First-example.png\" alt=\"Mobile view\" width=\"18%\"\u003e\n  \u003cimg src=\"/examples/Second-example.png\" alt=\"Mobile view\" width=\"18%\"\u003e\n  \u003cimg src=\"/examples/Third-example.png\" alt=\"Mobile view\" width=\"18%\"\u003e\n  \u003cimg src=\"/examples/Fourth-example.png\" alt=\"Mobile view\" width=\"18%\"\u003e\n  \u003cimg src=\"/examples/Fifth-example.png\" alt=\"Mobile view\" width=\"18%\"\u003e\n\u003c/p\u003e\n\n## Key principles\n- Uploaded files are processed entirely in memory and are never stored on disk. Once a request completes, no files or metadata remain on the server.\n- The app only modifies EPUB metadata (OPF and related fields). Book content, structure, and reading experience are left untouched.\n- The tool avoids deep EPUB “repair” or content manipulation to ensure results are easy to understand and trust.\n- Only EPUB files are supported. Other ebook formats are intentionally out of scope.\n- The application runs out of the box with no required configuration or environment variables.\n\n## What this tool is not\nNot an ebook library manager\nNot a reader application\nNot a full EPUB editor or authoring tool\nNot a replacement for Calibre or Sigil\n\n## Typical use case\nUpload an EPUB file\n- Inspect and adjust metadata (title, author, language, series, cover, etc.)\n- Optionally enrich metadata from public sources\n- Download a cleaned EPUB\n- Import the result into your library or reader of choice\n\n## Deployment\nThe application is distributed as a Docker container and can be run either behind a reverse proxy or directly via a mapped port. No volumes are required, as uploaded files are processed entirely in memory and never persisted.\n\n- Download the example compose file: [`docker-compose.yml`](/examples/docker-compose.yml)\n- Start the service from the same directory:\n  ```bash\n  docker compose up -d\n- The application listens on port 3007 by default.\n- Access it via http://localhost:3007, or expose it through a reverse proxy such as Caddy, Traefik, or Nginx\n\n\n## Like the project?\nPlease consider buying me a coffe, I really do drink it alot!\n\u003cp\u003e\n  \u003ca href=\"https://buymeacoffee.com/gjessing\"\u003e\n    \u003cimg src=\"https://cdn.buymeacoffee.com/buttons/v2/default-yellow.png\" width=\"80\" style=\"vertical-align: middle;\"\u003e\n  \u003c/a\u003e\n\u003c/p\u003e\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgjessing1%2Fepub-bookprep","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgjessing1%2Fepub-bookprep","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgjessing1%2Fepub-bookprep/lists"}
