How to Preserve PDF Image Quality When Saving in Word for Mac
Question details
The user wants to prevent a drop in image resolution when pasting a scanned PDF into a Word for Mac document.

- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Inserting a scanned PDF into a Word document while trying to maintain original high image resolution upon saving and reopening.
- Observed behavior
- When pasting a PDF directly into Word, the application converts the PDF to a lower-resolution format like EMF or PNG, resulting in a noticeable loss of quality after the document is saved and reopened.
Ensure you have the native macOS Preview application available, as you will need it to export your PDF files into high-quality image formats before inserting them.
Convert PDF to TIFF or PNG using Preview Before Inserting
Exporting the PDF as a high-resolution bitmap image ensures Word retains the original quality without compressing it through internal conversion.
Microsoft Word for Mac does not natively save pasted PDFs as embedded PDF files. Instead, it converts them into lower-resolution formats like EMF or compressed PNGs to save space. Converting the PDF to a high-quality uncompressed format like TIFF or PNG first bypasses this limitation.
Right-click your scanned PDF file in Finder, select 'Open With', and click on 'Preview'.
In Preview, go to 'File' > 'Export...' in the top menu bar. Choose TIFF or PNG as the format, set the resolution to at least 300 pixels/inch to maintain high quality, and click 'Save'.
Open your Microsoft Word document. Navigate to the 'Insert' tab on the ribbon, select 'Pictures', then 'Picture from File...', and choose the high-quality TIFF or PNG you just exported.
To prevent further quality loss, go to 'File' > 'Reduce File Size' in Word and ensure picture quality is set to 'High Fidelity' or 'Keep Current Resolution'.

Frequently Asked Questions
Why does Word for Mac compress pasted PDFs?
Word is designed to optimize document file sizes for easier sharing. When you paste a PDF directly, Word's internal rendering engine converts it into an EMF or a low-resolution PNG, permanently discarding the original high-resolution data.
Is TIFF better than PNG for inserting into Word documents?
Both TIFF and PNG are lossless formats that retain high image quality. TIFF is often preferred for high-resolution scanned documents and professional print work, while PNG is universally compatible and usually produces slightly smaller file sizes.
How do I stop Word from compressing images globally on Mac?
In Word for Mac, you can go to 'File' > 'Reduce File Size' and select 'High Fidelity', or ensure 'Keep Current Resolution' is checked. Note that this prevents future compression upon saving but does not reverse the initial conversion quality loss of directly pasted PDFs.
Can I embed a PDF as a clickable object in Word for Mac?
Unlike the Windows version, Microsoft Word for Mac has limited support for embedding PDFs as interactive OLE objects. It typically displays only the first page as an image. This is why converting the PDF to a high-quality image format first is the most reliable workaround.
