Draftable Clean supports the following file types for metadata scanning and cleaning:
File typeExtensions
Word.docx (Word Document), .doc (Word 97-2003)
PDF.pdf
Archive.zip (ZIP compressed folder)

​
Word and PDF files

Word and PDF files are scanned individually and assigned a risk rating based on the metadata detected. Each file can be expanded to review its metadata categories before cleaning. For a detailed list of every metadata type that Draftable Clean can detect and clean, see Supported Metadata Types.

​
Password-protected files

Draftable Clean supports password-protected Word and PDF files. If a file requires a password, it will display a PASSWORD status badge (highlighted in orange) and show a Password Required prompt. Enter the password and click Check Password to authenticate. If the password is correct, the file is scanned and its status changes to SCANNED with a risk rating. If the password is incorrect, a Password Invalid message is displayed — re-enter the correct password and click Check Password again.

​
Cryptographically signed PDF files

When Draftable Clean detects a cryptographic digital signature in a PDF file, the file cannot be cleaned. This is by design — removing or modifying metadata would invalidate the signature, as it proves that part or all of the document is unchanged. To preserve signature integrity, Draftable Clean skips cleaning for these files.
This applies specifically to cryptographic digital signatures, not to visual signatures or annotations created with tools like Adobe Fill & Sign. Those are standard document content (text and image objects) and do not prevent cleaning.

​
ZIP files

When you upload a ZIP file, Draftable Clean scans the metadata of the archive. Cleaned ZIP files are included alongside other cleaned files when saving or emailing.

​
Coming soon

Support for additional file types is planned for upcoming releases:
  • Excel (.xlsx, .xls)
  • PowerPoint (.pptx, .ppt)
  • Image files (.png, .jpg, and other common image formats)

​
Unsupported file types

If you try to add a file with an unsupported file type, Draftable Clean will notify you that the file cannot be processed.
In the Draftable Clean Outlook add-in, if you attach a file with an unsupported format, the add-in displays an “Unsupported format” status with the message: “This file type cannot be cleaned.” A link to the Knowledge Base is provided for more information on supported formats. Unsupported files do not block sending by default. You can configure this behavior in Settings > Add-In > Send Protection, where each scenario (unsupported attachment types, attachments not finished cleaning) can be set to Allow, Prompt, or Block.
