This question comes up with some regularity on AcrobatUsers. I am in a print for pay environment and i am needing to know if acrobat 11 pro can be used to see what the dpi of a file is. Or does the file have to be opened in in design or illustrator to find that out. I am the production manager in a digital print center. Technically it not possible to do this for an entire PDF file, because only the raster images within a PDF have a specific dpi or resolution.
But, if you have the Pro. The tool to check the dpi for individual images is the Output Preview tool located under the Print Production panel. In the Output Preview dialog, select Object Inspector from the Preview dropdown, then move and click the cross-hair pointer on top of any image within the file. All the image information will appear in Output Preview display.
To view all the sticky notes, open the Comments List located under the Comment pane. You can also create a summary of all the sticky notes by selecting Create Comment Summary from the Options dropdown. Now, this could get rather tedious if you have many files with several images.
So, to automate the reporting process, open the Preflight tool also located in the Print Production panel. Click on the Single Checks Icon at the top. This will return the results for you and allow you to create a report by using the Create Report… button in the lower right portion of the Preflight dialog.
How to determine the dpi of a PDF file
You can also automate this entire process by creating an Action and running the Action on a folder of PDF files. Lori, this is a great post. Very useful!!! Many thanks! Is there a way of highlighting images below ppiin the single action, preflight?

In most cases, the default settings are appropriate for maximum efficiency—saving space by removing embedded fonts, compressing images, and removing items from the file that are no longer needed. The space audit results may give you ideas about where best to reduce file size. Note: Some methods of compression may make images unusable in a print production workflow. Auditing the space usage gives you a report of the total number of bytes used for specific document elements, including fonts, images, bookmarks, forms, named destinations, and comments, as well as the total file size.
The results are reported both in bytes and as a percentage of the total file size. The PDF Optimizer dialog box opens. From the functionality perspective, both the options are the same.
Choose the location to save the file and click Save. Select the version compatibility that you need, and click OK.
In the Output Options dialog box, specify your folder and filename preferences, and click OK. To use the default settings, choose Standard from the Settings menu, and then skip to step 6.
The options available in panels vary depending on this choice. Select the check box next to a panel for example, Images, Fonts, Transparencyand then select options in that panel. To prevent all of the options in a panel from executing during optimization, deselect the check box for that panel. Optional To save your customized settings, click Save and name the settings. To delete a saved setting, choose it in the Settings menu and click Delete.
Note: To optimize several documents at the same time, use the Output options for the Actions Wizard. The Images panel of the PDF Optimizer lets you set options for color, grayscale, and monochrome image compression, and image downsampling. Reduces file size by lowering the resolution of images, which involves merging the colors of original pixels into larger pixels. Note : Masked images and images with a size less than by pixels are not downsampled.
Reduces file size by eliminating unnecessary pixel data. ZIP is the better choice for illustrations with large areas of solid, flat color, or patterns made up of flat colors. For JPEG compression, you can also specify lossless so that no pixel data is removed.The initial view of the PDF depends on how its creator set the document properties.
For example, a document may open at a particular page or magnification. The basic reading controls, such as page navigation and zoom, appear in a semi-transparent floating toolbar near the bottom of the window. You can also click the collapse button in the floating toolbar. In Full Screen mode, only the document appears; the menu bar, toolbars, task panes, and window controls are hidden. Full Screen mode is often used for presentations, sometimes with automatic page advancement and transitions.
The pointer remains active in Full Screen mode so that you can click links and open notes.
How to Check the DPI of a PDF in Adobe
You can use keyboard shortcuts for navigational and magnification commands, and you can set a Full Screen preference to display Full Screen navigation buttons that you click to change pages or exit Full Screen mode. This helps keep the focus on the content and the received comments. These buttons appear in the lower-left corner of the work area. If the Full Screen navigation bar is not shown, you can use keyboard shortcuts to navigate through a PDF. Note: If you have two monitors installed, the Full Screen mode of a page sometimes appears on only one of the monitors.
To page through the document, click the screen displaying the page in Full Screen mode. Then click the Full Screen tool to switch to Full Screen mode. Follow the steps in the article to close the Tools pane in Acrobat DC. You can change the overall look and feel of Acrobat by setting the display themes. The Preferences dialog box defines a default page layout and customizes your application in many other ways. The preferences settings control how the application behaves whenever you use it; they are not associated with any particular PDF document.
Note: If you install any third-party plug-ins, set these preferences using the Third-Party Preferences menu item. Searches the PDF for items that may not be apparent, such as metadata, file attachments, comments, and hidden text and layers. The search results appear in a dialog box, and you can remove any type of item that appears there.
Note: Transactional messages, which facilitate the Adobe Online Service, cannot be turned off. Note: Two conditions can affect page layout and zoom.To start the conversation again, simply ask a new question.
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.

Setting Up Adobe Acrobat and Reader on Windows 10
May 2, AM in response to tdadesign In response to tdadesign. Unless I'm missing something I've also tried this many times in the pastit's pretty much impossible.
As a test, I created a simple page in InDesign CS6 and dropped a small 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 dpi. Now just try and find out what that dpi is in the PDF file. Nothing tells you what the dpi of any embedded image is.
You can get the color space and pixels dimensions, but not dpi. May 2, AM. Feb 2, AM in response to tdadesign In response to tdadesign.
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. Feb 2, AM.Password Notices Tip Got Facebook?
I've spent the day working on a heavily-illustrated scanned book, OCRing it in Finereader then adding some finishing touches in Adobe Acrobat 4 ancient version but it still works. The problem was, Finereader kept crashing, the whole PDF was so large. After hours of tweaking, I thought I had great results, but then I decided to try viewing it in two-page view so that I could see both halves of an illustration on two pages.
The actual images are the same size, but Acrobat is interpreting them as being different because it thinks that they are different DPIs. Another possibility is to do it in Finreader itself, you can do it from the original files or reloading the final copy of the pdf I advise you to do in 1 above.
Note that I do not know what version of Finereader you have but in version 9: 1 - after opening your pdf file, choose save as pdf; 2 - in the windows that opens to save choose options; 3 - from the window that opens, choose picture settings and from the options available choose custom; 4 - from the window that opens choose one resolution that is less than the lower one you want to compress.
If your smaller resolution is less the 96 dpi you will not be able t resolve your problem this way. Best regards. Thanks for the tips, but I still haven't found a satisfactory solution.
I redid the individual pages that were a problem in that one document, but it looks like all the PDFs I've been created have been being reported as being what looks to be 72dpi the typical figure used for "screen resolution" when they were scanned at dpi.
Which explains why I was having a problem viewing the final PDFs on my Sony Reader-- it would look great but small on the full-page view but the text would be massively oversized when I reflow to medium font, and too big to show up at all at large font.
I don't want to redo all the PDFs, I don't want to throw away resolution-- all I want is to modify the PDF file so that it knows that those "72dpi" images are really dpi, therefore from pages around 6 inches across and not pages around 25 inches across like the PDF thinks that it is. I don't see any reason why that is something that could not be easily fixed-- change a couple of bits in the settings of the PDF or at worst tell it to change a couple of bits on every page. But it doesn't seem like Acrobat or anything else?
Acrobat itself doesn't have a way to do this that I know of ; there are plugins that will. FineReader should let you export with a choice of DPI options; you should be able to re-output the pages with different settings. You can in Acrobat 7; I don't remember if you can in 4.

Searchable Image retains the underlying scanned image and adds an invisible layer of text on top which may be selected:. ClearScan offers improved text quality with a decrease in file size:. Read on to learn about size comparisons, how to use ClearScan OCR and a bit more about how it all works.
In addition to Acrobat, I also had Excel running. At dpi, ClearScan offered improved visual quality at aboutone-third the total file size. At dpi, the ClearScan file was seven times smaller and looked better. ClearScan works by turning the images which represent text characters on the page into smoothed vector outlines.
Each character on the page is compared and all matching characters are replaced with a an outline character:.
ClearScan does not replace the font with your system fonts. Rather,a custom font it is created to match the visual appearance of the pixels. Besides better visual appearance, print time is reduced. Instead of sending large images to the printer, Acrobat can send the compact font information instead.

You can use the build in Preflight function. There are also other plugins and stuff, but as there is this built in option I don't think you'll need it. For more stuff on the topic just google for " image dpi in pdf " and you'll find lots on the topic. If you do this a lot and have a specific standard you want to always hit e.
Then in the "Images" tab you can set it to give you an error message or a warning when you run this preflight check if any image is below or above a set PPI:. The handy thing about preflight profiles is, you can include any checks you want at once. So you can also include other common checks, like warning you if anything is in RGB, listing fonts, warning you if any fonts are not embedded, mentioning if there's an odd number of pages or if any pages are blank, etc etc, all in one handy one-button check.
First, make sure the measurement units in your Preferences are set to inches. Adobe may not realise that.
Call up the Output Preview dialog. Its location in the drop down menus is different from one Acrobat version to another, so I added it to my standard toolbar:.
The default option is to show "Separations"; the third choice in the 'Preview' list is "Object Inspector". Select this option. Now details will be shown for every object you click on.How to Reduce a PDFs File Size using Adobe Acrobat Pro

Ah, okay, so one has to run a preflight, and the the images and their dpi is found in the results list. Thank you. Clicking any takes you straight to that image, with a dotted line around it.
