How can I find out the dpi of an image in Acrobat. I have tried the pre-flight option but I really don't understand the pixels width x depth information that I get. I basically just want to know at dpi of a single image. Is there other program that will read my pdf file and tell me this information.
Thanks Frank for quick response. But I can't find the "image" menu. I have Acrobat Pro 9. This is driving me insane.
Open the PDF in Adobe Reader or Acrobat.
Find the "Image" menu at the top of the window and then select "Image Size." A new window will open, displaying the "Pixel Dimensions" and "Print Size" of the image.
Try Adobe's forum. It's their product.
Then as klaus1 wrote you'll need to try Abobe support.
good luck
regards
Unless I'm missing something (I've also tried this many times in the past), it's pretty much impossible. As a test, I created a simple page in InDesign CS6 and dropped a small 300 dpi image into the page along with a text box. I saved it out through Acrobat 11 via InDesign's menu links with no compression or re-sampling allowed to the image. This means the image embedded in the PDF is still 300 dpi.
Now just try and find out what that dpi is in the PDF file. I opened the PDF in Acrobat 11 and tried every possible info menu I could find. Nothing tells you what the dpi of any embedded image is. You can get the color space and pixels dimensions, but not dpi.
Advanced > Print Production > Output preview
then, in the menu PREVIEW you click on Object Inspector.
Everywhere in the pdf you'll click, the object inspector will give you all the available info about that element in the page, including the resolution
Thank you, tylerdurdain! That was ridiculously difficult to find. Not sure what version of Acrobat you're using in your image, but for those using Acrobat Pro 11 (in Mavericks), it's buried under View > Tools > Print Production.
That opens a panel on the right.
To keep from having to chase it down this way each time, right click on "Output Preview" and choose "Add to Quick Tools Toolbar". That adds a button to the top right of the toolbar.
Now you can call up the inspector with one click. Choose Object Inspector as tylerdurdain shows above, then click on the item displayed to get its properties.
