Metadata

How to clean a PDF before you publish it online

By DeckleUpdated

To clean a PDF before you publish it online, finish all edits first, remove unwanted pages, then open Remove PDF metadata, tick the author, dates, app names, XMP packet, document identifier and any attachments, and choose Remove metadata. Keep a clear title. Then open the "(clean)" copy and read every page, because names and notes on the pages are not metadata and stay in place.

How to clean a PDF for publishing with Deckle

  1. Make your final edits in the source app and export the PDF.
  2. Remove draft pages, internal notes or blank pages with Organize PDF pages, and choose Save pages.
  3. Open Remove PDF metadata and choose the PDF, or drop it onto the page.
  4. Tick Author, Subject, Keywords, Creator, Producer, Created, Modified, the XMP packet, the Document identifier and any Embedded attachments. Leave Title unticked if it is correct.
  5. Choose Remove metadata and download the "(clean)" copy.
  6. Rename the file to something readers and search engines will understand, such as annual-report-2026.pdf.
  7. Open the final file, check its document properties and read each page before you upload it.

The result screen states how many items were removed. Deckle reopens the new file, checks that every item you ticked is gone and compares each page with the original.

What to keep and what to remove

Search engines and browsers show some PDF metadata to readers, so a published file needs good properties as well as no private ones.

Item For a public PDF Why
Title Keep, if it is the real document name Browser PDF viewers can show it in the tab, and search engines can use it
Author Remove, or set it to the organisation in the source app A personal name or login is rarely meant to be public
Subject, Keywords Remove unless written for readers Template leftovers look careless
Creator, Producer Remove They name your internal apps and versions
Created, Modified Remove when timing matters They can show a document was drafted long before an announcement
XMP packet Remove It repeats the fields above and can hold edit history
Document identifier Remove It can tie the public copy to internal versions
Embedded attachments Remove unless they are meant for readers They can contain whole source files

If the title reads "v9 FINAL (2)", fix it in the source app and export again rather than publishing it.

Check the pages, not just the properties

Metadata removal does not touch what is printed on the pages. Before publishing, read the final file for:

  • reviewer names, comments and tracked-change markings that were printed into the page,
  • "Draft" or "Confidential" headers and footers,
  • personal details in signature blocks, forms or appendices,
  • text hidden under images or shapes, which can still be selected and copied.

Try selecting and searching the text on each page. If something should not be public, remove it in the source document and export again. How to review hidden PDF information has a fuller checklist.

Order matters

Every app that saves the PDF can write new properties. Clean in this order:

  1. Edit and export.
  2. Merge, reorder, rotate or remove pages.
  3. Remove metadata.
  4. Upload.

Do not add a password to a PDF meant for public download. If you protect a document for a limited audience instead, clean it first and then use Password protect PDF.

Tips

  • Use a descriptive file name. It appears in the address bar and in search results, and an internal name like final_JS_edits.pdf gives away more than the Author field.
  • Keep a private master. Deckle never changes the original, so the full version with its history stays on your device.
  • Check text is selectable. A public PDF with real text can be searched and read by screen readers. If you exported pages as images, see text PDF vs image PDF.
  • Recheck after any change. If you replace the file later, clean the new version too.

Frequently asked questions

Does a PDF's metadata appear in Google search results?

Search engines can use the title, and the file name is visible in the URL. Other fields are readable by anyone who downloads the file.

Should I remove the title from a public PDF?

Usually not. A clear title helps readers and search engines. Remove it only if it is wrong or internal, and set a better one in the source app.

Will cleaning the PDF change how it looks?

No. Pages are copied unchanged. Only the ticked metadata is removed.

Is the PDF uploaded to clean it?

No. Remove PDF metadata works in your browser and does not upload the file.
