processing capabilities implemented in Go.\n\nIt focuses on correctness, robustness and independence from external dependencies.\n\n---\n\n## Focus\n\n- comprehensive PDF processing functionality  \n- minimal external dependencies  \n- predictable and stable behavior  \n\n---\n\n## Documentation\n\n* Project documentation: https:\u002F\u002Fpdfcpu.io\n\n### CLI\n\n* Command help: `pdfcpu [command] --help`\n\n### Go API\n\n* Package documentation: https:\u002F\u002Fpkg.go.dev\u002Fgithub.com\u002Fpdfcpu\u002Fpdfcpu\n* API documentation: https:\u002F\u002Fpkg.go.dev\u002Fgithub.com\u002Fpdfcpu\u002Fpdfcpu\u002Fpkg\u002Fapi\n* Examples:\n\n  * https:\u002F\u002Fgithub.com\u002Fpdfcpu\u002Fpdfcpu\u002Ftree\u002Fmaster\u002Fpkg\u002Fapi\u002Ftest\n  *

[issues](https:\u002F\u002Fgithub.com\u002Fpdfcpu\u002Fpdfcpu\u002Fissues\u002Fnew\u002Fchoose)\n* Discuss ideas on the [discussion board](https:\u002F\u002Fgithub.com\u002Fpdfcpu\u002Fpdfcpu\u002Fdiscussions)\n* For PRs, please open an issue or discussion first\nv\n### Guidelines\n\n* Base your work on the latest commit\n* Include verbose output (`pdfcpu cmd -vv ...`) and a sample PDF when reporting issues\n* Please sign your commits\n\n### Reporting crashes\n\nCrashes may occur due to the wide variety of PDF producers and formats in use, including older or non-compliant files. In many cases this is related to validation issues or edge cases in the parser.\n\nEven with relaxed validation, some files cannot be processed. These cases are essential for improving pdfcpu by extending validation and handling additional real-world PDFs.\n\nIf you encounter a crash, please report it.\n\nStart by validating the file using the CLI:\n\n```bash\npdfcpu validate -vv \u003Cfile.pdf>\n```\n\nInclude in your report:\n\n* the command used\n* verbose output (`-vv`)\n* a sanitized sample PDF\n\nIf validation crashes for a PDF that opens in Adobe Reader or macOS Preview, it is likely we can extend relaxed validation and provide a fix.\n\nIf the file cannot be opened by both Adobe Reader and macOS Preview, we cannot support it.\n\nPlease include a sample PDF to reproduce the issue whenever possible.\n\n---\n\n## Contributors\n\nThanks 💚 to all contributors:\n\n\u003C!-- ALL-CONTRIBUTORS-LIST:START - Do not remove or
