Draftable Clean Supported file types

Draftable Clean supports the following file types for metadata scanning and cleaning:

​

Document files (Word, Excel, PowerPoint, and PDF)

Word, Excel, PowerPoint, 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, and cleaning behaviour is controlled through your cleaning profiles.

• Excel (.xlsx) — Workbooks are scanned and cleaned using the same review workflow as Word and PDF files. Excel-specific metadata — such as formula cell references — can be reviewed in the viewer.
• PowerPoint (.pptx) — Presentations are scanned and cleaned using the same risk-rated workflow, with PowerPoint-specific metadata available for review before cleaning.

For a detailed list of every metadata type that Draftable Clean can detect and clean — including Excel-specific and PowerPoint-specific metadata — 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.

​

Image files

Draftable Clean supports .jpg, .jpeg, .png, .tiff, .gif, and .bmp image files. Images are scanned for embedded metadata — such as EXIF data, GPS location, XMP and IPTC tags, camera maker notes, and colour profiles — which is removed according to the active cleaning profile. The profile editor exposes the metadata types relevant to images so you can configure image cleaning with the same granularity as document formats.

​

Converting Office files to PDF

Draftable Clean can convert Word, Excel, and PowerPoint files to PDF as part of the clean — in both the desktop application and the Outlook add-in. In the desktop app, click the inline PDF icon on a file (it turns blue when flagged) or select files and click Convert in the toolbar. Flag supported files before or after cleaning to address metadata and deliver a consistent output format in one step.

​

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.

​

Unsupported file types

In the Draftable Clean Outlook add-in, if you attach a file in a format Draftable Clean does not support, 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.
