How to find Image DPI/PPI in word

Hi all,

Could any one know how to find out image DPI/PPI in word. Is any possibilities to identify using macro.

I am preparing document for printing so I need to identify low resolution image using their PPI/DPI.

Thanks,
Krishna

Word changes the dpi of the image when it is inserted. The resulting resolution depends on the selected default resolution. Go to File > Options > Advanced. You can select resolutions up to 330 ppi, or select "High fidelity" which avoids compression. This is the default in Office 2016.

However, if the image has less pixels than required for good printing, Word cannot increase the image quality, so he result will still be poor.

As a result, what you require cannot be done. When you insert the image, Word changes the resolution, depending on the setting. And, once the images are inserted, Word no longer knows the resolution of the original.

I not asking about word option. I am preparing word document for printing. So I am checking print preflight to converting word document into PDF and checking image resolutions and DPI/PPI. If it is low resolution image then again i am opening word document and replacing image and convert to pdf and again checking. Its getting more time to and time.

So, I want a tool to check those thing in word surface itself. So any way to find out. Can we use adobe DLL to reference in macro and do or with help of dot net using adobe dll reference.

As I explained in my last comment, once the image is in the doc, you can no longer check its resolution. Word can keep the original resolution, or change it into one of its own, up to 330 dpi. But it will not tell you what that resolution is. Even going back to the original image does not get you its resolution within the doc (unless Word is set to high fidelity) - but at least the original image can tell you how bad it could be when printed.

If all you want to do is to check the resolution of the image before inserting it in Word, and you want to do it inside Word itself, here's what you can do.

Go to Insert > Picture. Find the image you want and right-click it. Now select Properties, and then the Details tab. That will tell you the size of the image in pixels. To get the resolution, divide the number of pixels by the size at which it will be inserted in the doc. For example, say the image size is 1024 x 768 pixels and it will be inserted so its size (as printed) is 4" x 3". In that case the resolution will be 1024/4 = 256 dpi.

Word also shows a resolution, below the image size, but that is meaningless for you, as the real resolution will depend on the image size after insertion.
