How to reduce file size in Acrobat XI?

How can I to reduce the file size is Acrobat XI Pro? Up until v.9, it was just a matter of opening the pulldown menu Documents > Reduce File Size. and then some more. How's that done in the newer versions of Acrobat?
This was simple and easy:

Works like a charm... I have a pdf file of a A1 size drawing that went from 6,7 to 1.7 Mb. The rendered image became slightly grainier (hardly noticable), but the text recognition stayed intact. Magnificent!
FYI I've tested this file size reduction in three different runs:
Save As Other... > Reduced Size PDF... (Acrobat 1.4 comp.) 1,69 Mb
Save As Other... > Reduced Size PDF... (Acrobat 1.6 comp.) 1,75 Mb
Save As Other... > Optimized PDF... 1,73 Mb

Reduce File Size in Acrobat Pro (9.5.5) Corrupts Graphics in PDF Documents - shows up as black image

Whenever I use Reduce File Size in Acrobat Pro (9.5.5), sometimes some of the images (not all) get corrupted and show up as a black image in the new document.
Actually, the new reduced document looks okay when viewed in Acrobat, but the problem shows up when viewed in the Preview application on the Mac.
I'm using Acrobat 9.5.5 with Mac OS 10.8.6
I've tried re-importing the graphic into a new graphic box, which didn't work. Thinking there may be some type of corruption with the actual graphic file, I then tried viewing the graphic, then taking a screenshot of it to create a completely new file, and then re-importing the new graphic file into the original document (created in Adobe In Design 5.0.4). I then export the new document as a pdf, and brought it into Acrobat Pro to do the Reduce File Size. Same thing happens - black box appears where the graphic was.
I then tried using the Reduce File Size within the Save As function of the Preview application on the Mac - while the graphic remains intact, many of the other graphics in the document are "reduced" too much, to the point where the image quality is seriously degraded, and therefore not usable.
Any other ideas?

Hi Anoop,
I can share the graphic file, but not the pdf which contains it (as it contains confidential information) - thanks!

Issues in Reducing file size on Acrobat 9.3.1

The text has been merged or split on Acrobat 9.3.1 Pro by using the option "Reduce File Size" or "PDF Optimizer". There is no issue in the earlier version of Acrobat (7.0 & 8.0). We are using the Mac OS between 10.4.11 to 10.6.2. I have attached screenshots for your reference; please look at the Word "Issues" has been split after reducing file size on Acrobat 9.3.1. Is there any other way to do Hi-Res PDF to Low-Res PDF without any issue? Kindly help me out to sustain the best process in future.

I found a similar problem with text styled for small caps. It was fine in the original PDF, but became lowercase in the reduced file. The reduction process probably throws away characters from fonts that Acrobat decides are unnecessary.
I was able to partially solve the problem by combining multiple PDFs (book chapters) and selecting the smallest file size icon at the bottom of the page. Alternately, I chose a web-quality preset, which also worked. The file size might not be quite as small, but the files were good.

Making a interactive PDF from indesign, but it's too big. Tried to reduce file size in Acrobat, but it does not reduce file size.

Use the Optimize PDF command in Acrobat, it gives you more control. I think it's under the Advanced menu in Acrobat 9 Pro and File > Save As > Optimized PDF in Acrobat X Pro.
You might try playing around with different settings. You can also click the Audit Space button at the upper right to see if its from images or other things causing the file size problem.
Unfortunately, InDesign doesn't write interactivity in a very optimized way. You get better results with buttons, for example, creating them in Acrobat Pro and using the Duplicate command to duplicate them across multiple pages.

Reduce file size in Acrobat X

What is the best way to reduce file size? The Document menu is no longer an option. When I try to Save As... Reduced File Size or Optimized PDF, the program crashes.

We aren't Adobe. We're just users like you.
Regardless, this is something that requires Adobe Acrobat and not Adobe Reader. This is the Reader forum.

How to reduce file size

I have one page file. There is no image, just text. Now the file size is 3MB.
I cannot reduce size anyhow. I have moved the tick from embed fonts at save option tab but file size is same.
How I can reduce file size?
In addition this file is used so many times.

Probably not.
If you don't see the Master Page tab in Designer, then the way in which you imported the existing PD means that the page was brought in as artwork. I don't think you will be able to reduce it now.
One potential option would be to:
Go back to the existing PDF and export the page as an image. You can process the image in Photoshop (or similar) and get the image file size down.
Then start a new form in Designer and on the Master Page drag on an Image object and associate it with the image in step 1.
Save this new form and see is the file size acceptable. If so, proceed.
Now open your existing 3Mb form in Designer and copy all of the objects.
Paste these into your new form.
You may need to move things around a bit.
Hope that helps,
Niall

What do I loose with "Reduce File Size" to Acrobat 8.0 compatability?

When scanning documents using the Acrobat interface in 9.0, I find that the file sizes are very large...about 1.5MB per page. If I then select the "reduce File Size" option from the Document tab, and select Acrobat 8.0 and later compatibility, the file size is reduced by 10 fold....to something approaching 150 KB per page. I don't see degradation of the scanned image on my screen....but am I loosing image quality?

I tried it at home & I used the optimize pdf thing. It went from 17MB to 12MB so I re-optimized it & got it down to 3MB. It's as good as it is going to get. The big problem is that the .pdf that I have was scanned on a copier machine.
I printed the 3MB pdf on the color printer & it came out okay, but then I printed it on the black & white printer & it barely had any ink on the page....
I am just going to not bother with it anymore. Not much I can do with a scanned document & it's not even my job to begin with!
Thanks Bill.

Reduce file size in Acrobat 7

Is there a way to automatically reduce the file size in acrobat 7 so that it is compatible with version 4? I would like to be able to do this automatically instead of having to go to File=>Reduce file size and downsizing each doc individually.
Any help would be greatly appreciated.

I have the exact same problem and I'm running 7.1.0 on XP. I've tried the detect and repair and no dice.
What's really annoying is that every 6 mos or so some functionality is 'lost' and I have to re-install Adobe and download/install the updates.
I know there are newer versions of Acrobat, but frankly, although I use Acrobat frequently, it is simply to PDF files (nothing fancy, straight PDF) and getting a newer version doesn't seem warranted.
My paranoid self is beginning to believe that Adobe has an 'expiry date' - i.e., it begins to self-destruct if you haven't upgraded in 2 years or more?
Don't expect a reply, just venting.

How to reduce file size when using batch processing?

I use File > Process Multiple Files to batch process photos to a smaller file size along with adding my watermark. I've played with many different settings and no matter what I choose, I can't get my average file size to be less than about 200k. However, when I've exported the same photos using iPhoto, I can get the file size to about half of that with no difference (to my naked eye at least) in quality.
I definitely want to keep the height at 768 pixels so that needs to stay constant.
My current settings in batch processing (average file size = 200 kb)
Resize images with a height constraint of 768 pixels at 150dpi
What I've tried:
Resize at 72dpi (reduced file size by about 5kb)
convert file to JPEG low quality (reduced file size by about 10kb)
convert file to JPEG medium quality (not much difference in file size)
I'm using PSE 10 on a Mac running Lion.
Thank you in advance for your help!

You should go with default settings of Optimizer.
One difference between default settings of Optimizer and Reduce file size is that Optimizer does not guarantee a reduction in file size (if your Optimizer settings lead to an increase in file size, that's what you will get).
With Acrobat 9, the default setting in Optimizer has an additional setting which would not do an image optimization that results in increase of file size. In that sense it would in most cases give a smaller file.

How to reduce file size of pdf documents from 12 mb to 4 mb

i am trying to reduce file size at adobe reader original document size is 12 mb i need to get it down to 4 mb , please help how

You might be asking for the impossible or the easy. Acrobat Pro can reduce the size of PDF files, but nobody can promise any particular PDF can shrink.

Can using "Reduce File Size" in Acrobat Standard 9 effect DPI

I'm sure the answer is no to this question, but before I wholeheartedly recommend this fantastic tool for use throughout our firm, I need to know if there is the possibility of a PDF's functional DPI being reduced in a scanned PDF by using Reduce File Size. What I mean, I guess, by functional DPI, is the DPI in the PDF after running the tool. Courts require 300 dpi on scanned PDFs, which is our standard, but once in a PDF it's impossible to determine (as far as I can tell) DPI in a file. I notice no reduction in quality when using this tool, but want to make sure that we aren't circumventing court guidelines when using it to help reduce the size of files scanned at 300 dpi.

Hi Anoop,

Cannot reduce file size in Acrobat X due to "image masks"

Occasionally, when I try to reduce the file size of a PDF file in Acrobat X, I am getting the error message that the file was not re-rendered because of "image masks".
What precisely does this mean? How are image masks created in the PDF production process and how do I avoid them going into the file?
In this case, it was a simple Word document including a text and two semi-transparent GIF images on top of each other placed behind the text.
Any help would be appreciated!

Try to flatten the pdfs that should get rid of the masks (use Preflight tools).

REDUCE FILE SIZE with Acrobat Pro

Hi everyone!
I created a epk for a rock band with Illustrator then I created one pdf that contains the all three pages with Acrobat Pro (I downloaded the trial because it was just for this occasion) This epk is a pdf file with 3 pages, some pictures and hyperlinks.
I need to send the epk to the band and they want a reduced size one. The original is 8.3 M but obviously it's too big to be sent via email.
I have been trying with the option SAVE AS - REDUCED SIZE PDF but it doesn't work! Still the same size.
I am new to acrobat so maybe I am missing something.
HELP!
Thanks

Hi michelab,
You can also try choosing Save As > Optimized PDF. There are various settings in that dialog box that you can manipulate to bring down the file size. Here's the Help topic on that dialog box, with information about the various settings:http://helpx.adobe.com/acrobat/using/optimizing-pdfs-acrobat-pro.html
Please let us know how it goes.

Reducing file size in Acrobat Pro XI

Created a 36 page PDF from 300ppi scans of pages of a large 1822 Bible, applied OCR, resulting file size was 53, 149 KB. Need to get it down below 20,000 KB. Used "Save as Other>File Size Reduce" and "Save as Other>Optimize." Set the latter to Reader X, and minimum size. Result was no reduction whatever in file size. What's wrong?

I have Acrobat Pro X - so I'm not sure if XI has this same feature, or if it's in the same location, but see if you can try this:
Tools > Document Processing > Optimize Scanned PDF
I use this a lot to reduce PDFs that won't reduce through a Save As.
Hope this helps.

Captivate 6 - how to reduce file size

We are having problems reducing our Captivate 6 file (around 198 slides) from around 93MB. It needs to be a lot smaller (i.e. 30MB) in order to publish it as SWF file on our company website. Currently we can only publish some of the file.
It does have lots of widgets, photos & (non-linked) powerpoint imports.
I've googled this & read numerous forums & have tried everything - to no avail.
This is what I've tried so far:
1. Compacting the (non-linked) powerpoint imports.
2. Deleting unused library files.
3. Setting quality as 'Low'.
4. Reducing audio setting (there is no audio function anyway).
5. Clearing cache.
6. Cutting & pasting content into new blank file.
7. 'Publish Adobe connect metadata' unchecked (in publish settings).
Any ideas welcome ;o)

You should also look into the size of your images in your content. They may be far larger than they need to be.
Try going to each slide, selecting an image and clicking the option in Properties tab to Reset to Original Size. If you find images are then resizing huge, you need to go back to your source images, open them in a graphics editor (e.g. Photoshop or similar) resize the physical dimensions of the image so that they match the pixel dimensions required for your Captivate slide, create a version of the image at that size, and import THAT image into Captivate for your slide.
If your images are all way huge, then this can significantly bloat the published file size.
Finally, if there are any video files in your project, this will also likely blow the filesize out.
