Microsoft Word is heavily optimized to keep file sizes as small as possible. To achieve this, Word uses an automatic image compression algorithm. If you take a massive, 15-megabyte high-resolution photograph with your DSLR camera and paste it into a Word document, the software will silently “downsample” the image behind the scenes, permanently deleting pixels to compress the file size down to a standard 220 ppi (pixels per inch).
While this is great for emailing lightweight documents, it completely destroys image quality. If you are designing a brochure, a scientific report, or a flyer that you intend to print on a high-quality laser printer, Word’s automatic compression will result in your images looking blurry, pixelated, and unprofessional on paper.
You can force Microsoft Word to completely abandon its compression algorithms and preserve the raw, original quality of every image you insert.
How to Stop Word from Compressing Images
You must change the image fidelity settings within the Advanced Options menu.
- Open your document in Microsoft Word.
- Click on File in the top-left corner of the ribbon.
- Click on Options at the bottom of the left sidebar.
- In the Word Options window, select Advanced from the left-hand navigation pane.
- Scroll down the right pane until you reach the section labeled Image Size and Quality.
- Look for a checkbox labeled Do not compress images in file.
- Check this box.
- Right below it, locate the drop-down menu labeled Default resolution:. Change this setting to High fidelity.
- Click OK to save your changes.
From now on, Microsoft Word will never discard image data. If you paste a 4K resolution photograph into the document, it will retain every single pixel, ensuring your final printout looks exceptionally crisp and sharp (though be aware your .docx file size will increase significantly).
