Can Windows Tag PDFs? How to Tag PDF Files in Windows 11

Tag and rate your PDFs right in File Explorer — and find them again in one click.

Quick answer: File Explorer does not normally offer an editable Tags field for PDFs, even though PDFs can contain metadata. With Tag+ from Productivity Plus Pack, you select PDFs in File Explorer, right-click and choose a tag, then find them again from the Search filters section in the navigation pane or with Windows Search.

It's a common surprise: photos and Office documents have a Tags field under Properties > Details, but PDFs — often the very files you most need to find again — don't.

Tag+ and Rate+ from Productivity Plus Pack add tags and star ratings to PDFs, store them with the file, and make them searchable from File Explorer.

Step by step

  1. Select your PDFs. Select one or more PDF files in File Explorer.
  2. Tag or rate them. Right-click and choose a tag or a star rating, or press Ctrl+Win+Alt+T followed by a number key (1-9).
  3. Find them again. Open the Search filters section in Explorer's navigation pane and click the tag or rating.
  4. Let AI help (optional). Turn on Tag Sense AI to have tags suggested from each PDF's content — scanned PDFs included.

Ways to do it

Use what's built into Windows, the tools you already have, or Productivity Plus Pack — they work well together.

Built into Windows

Windows Search can find text inside PDFs when a PDF filter is installed, but Windows doesn't let you add your own tags or ratings to them.

With Productivity Plus Pack

Tag+ and Rate+ tag and rate PDFs from the right-click menu, and the tags show on thumbnails and in search filters.

Let AI suggest tags

Tag Sense AI reads PDFs, including scanned ones, and suggests tags using AI that runs on your own PC.

Where are PDF tags stored?

In a hidden NTFS stream attached to the PDF on your PC. The PDF's content isn't changed, and nothing is uploaded.

Do the tags stay if I copy the PDF to a USB stick?

Only if the drive uses NTFS. FAT32 and exFAT drives, common on USB sticks and SD cards, can't keep these tags. Photos and videos such as JPG and MP4 store tags inside the file, so theirs travel everywhere.

Can I comment on a PDF too?

Yes. Comment+ adds a comment to a PDF the same way, and you can find the file by its comment later.
