Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nRemove supported document properties and verify output; scope exclusions explicitly.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"remove-pdf-metadata\",\n  \"category\": \"pdf-tools\",\n  \"built\": true,\n  \"requirements\": \"Remove supported document properties and verify output; scope exclusions explicitly.\",\n  \"implementation\": {\n    \"fields\": [],\n    \"files\": true,\n    \"multiple\": false,\n    \"input\": false,\n    \"accept\": \".pdf\",\n    \"note\": \"Page numbers start at 1.

([Markdown](https://happytails.ai/en/pdf-tools/merge-pdf.md))\n\n- [Split PDF](https://happytails.ai/en/pdf-tools/split-pdf/): Save selected PDF pages as separate files. ([Markdown](https://happytails.ai/en/pdf-tools/split-pdf.md))\n\n- [Extract pages](https://happytails.ai/en/pdf-tools/extract-pages/): Create a PDF containing the pages you select. ([Markdown](https://happytails.ai/en/pdf-tools/extract-pages.md))\n\n## How to use Remove PDF metadata\n\n1. Choose a file in PDF.\n2. Review the settings, then choose Run Remove PDF metadata.\n3. Review the result, then use Copy result or a download link when available.\n\n## What to expect\n\nClear common document metadata from a PDF copy. This clears standard title, author, subject, keyword, creator, and producer values and removes the catalog metadata stream. It does not remove visible text or guarantee that every embedded object is free of metadata.\n"
