Last updated:July 8, 2026

When using WPS Attachments, common questions usually involve membership access, opening attached files, and PDF size changes; this FAQ covers 4 common questions and a glossary.

FAQ

Why is the Attachment button unavailable?

  1. Make sure the file you opened is a PDF rather than another document type.
  2. Check whether you are signed in with a WPS account that has the required benefits.
  3. Confirm that your current environment supports PDF editing, then reopen the file and check the related entry again.

What file types can I attach?

  1. You can attach common document files, images, compressed folders, audio files, video files, and other local files.
  2. After you select the file, it is embedded into the PDF.
  3. If the file cannot be opened later, check whether your computer has a compatible app for that file type.

Why does the PDF file become larger after I add an attachment?

  1. The attached file is stored as embedded content inside the PDF.
  2. Larger attached files usually make the saved PDF larger as well.
  3. To control file size, attach only the files you need or compress the file before inserting it.

How can I view all attachments that were already added to the document?

  1. You can first look for attachment icons on the page and open them one by one.
  2. In some interfaces, you may also be able to view an attachment list from the left sidebar.
  3. If you do not see a list entry, use the attachment icons on the page first.
