View & Edit PDF Metadata

Quick answer: Inspect, edit, or wipe PDF metadata — title, author, creating software, and hidden history. Open PDF 元数据 — everything runs locally in your browser, and files never leave your device.

Steps

1. Upload the PDF to the Metadata tool to see every stored field.
2. Edit title, author, subject, or keywords as needed.
3. Before sharing externally, use "remove all metadata" to strip software names, edit history, and other traces.
4. Download the cleaned file.

Important notes

• Metadata edits never touch the visible content — they only change document properties.
• Files exported from Word or scanned on phones often carry your username and device name; clean before sending to strangers.
• The filename you see in a file manager comes from the OS, not the metadata.

Common questions

Why does a journal require metadata edits? Submission systems index papers by their Title/Author fields — mismatches break their records.

Can metadata prove creation time? No — it is freely editable and has no legal weight; use a trusted timestamp service for that.
