How to pdf metadata

  1. Drop the PDF.
  2. Type the properties you want to set.
  3. Press Save and download.

What happens to your file

Only the document information — the four fields readers show under Properties — is rewritten. Pages, text, bookmarks and form fields are not touched.

A field you leave empty keeps whatever the file already has; creation and modification dates and the producer are left as they are.

Questions

Why does the title matter?

Readers show it in the window and tab instead of the filename, search engines use it as the result’s heading, and screen readers announce it. A PDF exported from Word often carries the wrong one.

Does this remove hidden personal data?

No — it sets the visible properties. Comments, annotation authors and XMP metadata are not changed.

Do this in code

curl -X POST https://api.fylane.dev/v1/jobs \
  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "pdf.set-metadata",
    "options": {
      "title": "Leave empty to keep the current one",
      "keywords": "comma, separated"
    }
  }'

The same operation, pdf.set-metadata — Title, author, subject, keywords — written as an incremental update. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
