Reducing file sizes of multiple PDF's

Hello everyone,
I just got hired at a structural engineering company, and we are trying to go "paperless". I am in charge of scanning tons and tons of our old record drawings. We have an old scanner and the PDF's it creates are anywhere between 10,000Kb to 70,000Kb. After I scan every sheet, I am supposed to use the "Reduce file size" option in Adobe Acrobat. I am using Adobe Acrobat 7.0 Professional and I always make the files compatible with 5.0, which reduces the file size by 1/6 - 1/10. I've only been able to reduce 1 sheet at a time, which again, is time consuming. Is there a way I can reduce multiple files at once? I looked online and found an article here: http://help.adobe.com/en_US/Acrobat/9.0/Standard/WS65C0A053-BC7C-49a2-88F1-B1BCD2524B68.w. html, saying that in Adobe Acrobat 9.0, I can select "Apply to multiple" to reduce multiple files. Is there a way I can do it without upgrading?
Thank you in advance.

Unfortunately, it's not possible if you're using Acrobat XI. In previous
versions you can tell an Action to ignore non-PDF files but this feature
was removed in XI. Also, 35,000 files is way too much for Acrobat to
process. You need a more robust application for such a batch processing
task.

  • PDF Reduce File Size makes certain pdfs HUGE

    Generally reduce file size works great for me but certain files, those coming from someone using Microsoft Publisher in particular, result in larger pdfs. She sends me newsletters for a website and sometimes the 3 page pdfs are 2-4mb. I tried opening in Preview and re-saving them using the Reduce File Size filter and the result is that they ballon up to 50-100mb!! Info for the file reveals that the pdf producer is GPL Ghostscript 8.15 and the content creator is PScript5.dll Version 5.2.2. I seem to be able to open and reduce file size using Acrobat so I'm not quite sure why Preview is choking on them.

    Hi geekinthegarden- This does not surprise me. There are many variations and reiterations in specifications of the PDF format.
    Going from Ghostscript language interpreter, to Apple in rendering could introduce complications which we will not be able to sort out in this forum encapsulating a complete description of a fixed-layout 2D documents that includes the text, fonts, images, and 2D vector graphics which compose the documents.
    Suffice to say it is not a perfect science.
    Print PDF has a compress PDF file option as well as ColorSynch in your /Utilities folder +reduce file size+ option for PDF's. This may or may not be of use.
    You found your workaround using Acrobat, this is part of the value of having more than one PDF viewer, good computing!

  • How do you reduce file size of a PDF if Save As doesnt work?

    I have been trying to reduce the size of a PDF, using the Save As > Optimized PDF method.
    I have also tried Save As > Reduced Size PDF.
    This is on a file made up of 20 pages of full page Jpegs. (These were generated by the script in Photoshop that generates Jpeg files from Layer Comps within the document.)
    If I use Reduced Size PDF, I get a greatly reduced file size but the image quality suffers greatly. (Lots of artifacts and blurryness)
    There are no options to choose the level of compression I want.
    If I use Optimized PDF method, I cant seem to reduce the file size no matter what I set the Jpeg compression to.
    Is there some way to cut the size of the file down but not lose so much image quality?
    Any suggestions?

    Part of the problem here is that the files that are produced when I run the script to output files from layer comps are very big.
    If I "save for web" for each layer comp, I wind up with way smaller Jpegs. Thus a much smaller PDF.
    So the question is: Can you make the script, Layer Comps to Files, create smaller more optimized Jpegs? (Like you get when you save for web)

  • Reduce File Size and Optimise PDF both increase file size

    Hi All
    I have exported a pdf (our college mag) at smallest file size from Indesign CS4 for online use. The problem is the resultant file size is a little under 19Mb. Using both or either Reduce File Size or Optimise functions simply result in an increase to 22Mb. The document is packed with images however I would have thought one or both of these processes would have helped reduce the file size to a more manageable download file size.
    A pdf is also produced to go to print so simply compressing all images prior to imcuding them in Indesign is not a preferable option - this would mean creating two separate Indesign documents, something which I would rather avoid if possible.
    Any help would be greatly appreciated as always.
    The file reside here if anyone cares to take a look http://www.ayrcoll.ac.uk/index.php?name=UpDownload&req=viewdownload&cid=11&orderby=dateD  It's the latest release (September 09)
    Thanks

    You might want to do an audit of the PDF (button in PDF Optimizer) and try to figure out what the various parts are. It shows 58% is content streams (sorry, but I am not sure what that is), 26% is overhead, and only 12.7% is graphics. Since you are not storing bookmarks and such, you might want to try going back to ID and printing to the Adobe PDF printer for a comparison. It may be one technique is more efficient than the other.
    When I used the optimizer, the file did get larger. When I used Reduce File Size, it got slightly smaller. The key may be in figuring out what the various parts are from the audit. You might try copying one page of ID to a new document and play with various versions - different fonts (all were embedded and that is probably best), variations on graphics, etc. That is all I can suggest since I would simply be playing with different ways to produce the document and looking at what is causing the bloat. When the Images are only 12.7% and the fonts less than 1%, there is something going on to produce the size, and those 2 are typically the killers. I would mention tags that tend to bloat, but you do not have any (normally used for assessibility).
    You might want to try some of the preflight checks to find issues. I did the transparency check and got 170 instances in 22 pages. Flattening the page may help. There were some pages that seemed to be very bad. However, I did not get a big file size reduction. I did not get a lot of improvement by printing to a new PDF either. Certain pages seem to be part of the bloat problem. The print took a long time around pages 11 and 22.
    One troubleshooting technique would be extract pages to separate files and look at the details of each page to see what is causing the issue.
    Need to go. Good luck.

  • Reducing file size on multiple photos

    I up load my photos for prints. Most of my photos are 2+ mb in file size so when I am up loading a group of photos for prints it takes an hour or so at a time. Is there a way in Elements 4.o to reduce the file size of multiple photos simultaneously for up load without over writing the original image?
    I'm willing to save a copy of the images in the reduced file size that I could delete after up loading, but would love to find a way to reduce the file size on multiple images instead of "Save as" on each image.
    Any thought would be appreciated.

    Good evening
    Process multiple files (under File) should do what you want-you can select files from a folder, send them to a new folder (to save the originals), adjust size and quality. The pop up window is fairly straight forward, but post back if you have any questions.

  • Reducing file size #2...Preview, Quartz Filter vs Adobe Pro Optimize

    Questions on reducing a pages to pdf file…I will post each question seperatly.
    2) I read that you can reduce file size of a pdf in preview with a quartz filter. I created my own filer and it worked as expected. But, I also have Adobe Acrobat Pro, with save as PDF Optimized. The pro seems to have much more capability than the quartz filters.
    Is one better that the other to use? The adobe optimize (standard settings) took it from 20 to 6 megs.
    THanks, Bob

    The Adobe Acrobat settings you chose are probably using .jpeg to reduce the file size.
    .jpegs are lossy. ie You lose detail and sharpness the more you compress the image.
    The Quartz filters are usually of very high quality, but they are a black box and you need to understand what the settings are in each one. Quartz filters are extremely powerful, fast and as I said usually high quality but I suggest you experiment and see if they meet your needs.

  • 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 do I reduce file size in Adobe 9.4.5?

    Hello,
    I'm using Adobe 9.4.5. I can't figure out how to reduce file size. My 'save as' options don't offer this because they only offer 'save a copy' or 'save as text'. And I don't have the 'Document/reduce file size' option. It's simply not there.
    I'd appreciate any advice on how to do this.
    Many thanks.

    You can also try Document>Reduce File Size. The PDF Optimizer has more features, but Reduce File Size my meet your need. I find different results with both methods, making me sometimes wonder which is the best approach.

  • Reduce file size with action wizard

    (German version below)
    Hey,
    I got two questions for action wizard in Acrobat XI Pro.
    I try to reduze file size of many PDFs using acion wizard. My tests worked fine but now I got some problems I try to explain now:
    1. I add a directory with many subdirectorys to my process list. Adobe now adds not only PDFs to my list, it also adds JPGs, DOCs etc. That means I have to delete every single file I not want to convert to PDF cause I only want to reduce file size of excisting PDFs. Is there any possibility to only add PDFs in my processing list?
    2. If a PDF is opend by any other user I get a information about it. This info I need to acknowledge every time it pops up cause my process interrups. Is there any possibility to ignore this info?
    I´m happy for any help i can get here. Thx.
    Regards
    (Sorry for bad english, it´s not my favorite language )
    Hallo Leute,
    ich benötige Hilfe beim Benutzen des Aktionsassistenten im Acrobat XI Pro.
    Ich versuche bei sehr vielen PDFs die Dateigröße zu verringern. Dazu habe ich mir eine Stapelverarbeitung per Aktionsassistent erstellt die bei meiner Testumgebung auch super funktioniert. Leider habe ich noch einige Probleme für die ich Hilfe benötige:
    1. Wenn ich einen Ordner mit sehr vielen Unterordnern und verschiedenen Inhalten einfüge möchte ich eigentlich nur die PDFs verarbeiten. Leider fügt Acrobat auch alle JPGs DOCs etc. hinzu. Ich muss also alle unerwünschten Dokumente herausfiltern, da auch keine sortierung vorhanden ist. Bei mehreren Tausend Dokumenten nicht leistbar. Gibt es hier eine Möglichkeit nur PDFs in die Stapelverabeitung aufzunehmen?
    2. Sollte die Verarbeitung mal laufen kommt es hin und wieder vor das die PDFs durch einen Benutzer geöffnet sind. Ich bekommen hier eine Meldung von Acrobat die ich erst bestätigen muss bevor es weiter geht. Da das Programm eigentlich über mehrer Tage/Wochen im Hintergrund laufen soll passt mir das gar nicht wenn ich alle Stunde überprüfen muss ob die Stapelverabeitung noch läuft.
    Ich hoffe es gibt jemanden der mir helfen kann. Ich bin über jede hilfreiche Antwort glücklich.
    Gruß

    For starters, let's refer to your original post: "this is indeed a serious problem and step back in functionality..."  This statement is a quite ridiculous assertion, unnecessarily dramatic, wholly inaccurate, and unhelpful.  Your statement "is this a joke" and "I know Acrobat tends to choke...etc..." is just pure gibberish and polemical.   It is quite easy to feed any application enough data to cause a performance failure, but one would really need to question one's motive and prudent use of one's time at this point - unless you are tasked with stress and load testing the software to determine minimum working requirements.  
    'Batch Processing' is, since Acrobat 9.x, dead and gone, Acrobat 11's approach is to aggregate many hitherto unavailable tools and commands and allow the user to create custom workflows.  More interactivity has been built into the process, which may or may not be desirable in each case depending on the workflow context and requirements.  But we have obviously moved away from the concept of processing a large number of files and towards a more targeted and effective processing of smaller sets of files.  The default Actions we deliver with Acrobat 11 reflect this intention.
    The feature "Batch Processing", which was an Acrobat feature from A5 (I believe) up to A9, previously had been hidden in Menu/Advanced/Document Processing/Batch Processing has been wholly replaced by a completely overhauled framework called Actions, now part of the Tools panel, and will be immediately accessible when Tools is called in the UI.
    Thus the obscured Batch Processing may have been a tool considered and used by an extremely small set of users to do exactly that, i.e., batch process a large number of files, but had been fairly inflexible, generally speaking, and buggy.  We were very well aware that if we were to overhaul the feature, add a considerably larger number of available tools and commands in Acrobat, provide wide possibilities for customization built towards specific workflows, and bring it to the forefront, we were going to sacrifice some of the aspects of batch processing a large number of files.  Not calling it "Batch Processing" anymore - because it isn't - may be an indication of this intention.
    Personally I have used and tested Batch Processing periodically during various Acrobat projects, but I don't remember encountering the "Reduce File Size" command - which is a subset of Save and file optimization -  to use within a batch sequence.  I may be wrong, and your screen shots would be welcome here.  In fact go ahead and construct a batch sequence that (1) uses 'Reduce File Size and (2) applies file type filters to it, and post it either here or to me privately.  I would be happy to be wrong.  But regardless, we are grateful for positive input that points out defects, allows us to improve the functionality of the product, providing the intended changes are reasonable, and that the communication of said issues remain respectful of this process and of the individuals we depend upon to implement these changes.  The tone of your response comes very close to rendering a proper consideration of this issue irrelevant.

  • Reduce file size makes documents much larger.

    In my new Acrobat 10.1.6, "reduce file size" and "optimize" keep making the document much, much larger. Reduce file size even took a document previously at 3.3 mb and turned it into 24 mb. So I took the same document and went back to my previous Acrobat 5, and it actually reduced the file size as expected. What's going on?

  • Need help reducing file size.

    We're using Acrobat 8 Standard and are able to reduce an 8 MB file down to 7 MB but a fellow employee with Acrobat 9 Pro was able to reduce the size of the same file to 1.8 MB. We're doing the same function (Reduce File Size) in both apps so we're not sure why there's such a big difference in finished file sizes between the two programs. Is there a setting in Acrobat 8 Stnd that we're missing to be able to drop the file size much closer to what Acrobat 9 Pro can achieve?
    Any help would be greatly appreciated.
    Thank you!

    There are a lot of factors that can affect file size. PDF Optimize allows you more control over those options that does the Reduce File Size. With PDF Optimize, you can do an audit of the PDF to see what is taking up a lot of the size. Things that can affect the size include:
    1. Image resolution (PDF Optimize can reduce)
    2. Embedded fonts (subset fonts recommended to reduce size - leaving the fonts out is not a good idea)
    - Other?
    That may help some. When you compare how different machines or versions of Acrobat do the file reduction, you need to simply review all of the options that are being used. Sometimes, you can get a reduction by reprinting to a new PDF, but that is not a perfect process either.

  • Making a interactive PDF from indesign, but it's too big. Tried to reduce file size in Acrobat, but

    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.

    You have two options:http://www.screencast.com/t/p3srGDGP
    In this screen shot I have two method chosen.
    the one highlighted in yellow is more effective, except in the case where the pdf was from a Scan which is graphics only.
    select the one in yellow first and click on Fonts. Remove all duplicates. for some reason, I don't know if its defect in Acrobat, but usually multiple copies of the exact Font will show up and some cases there will font families not even used in your document.  remove all duplicates.
    Note: Duplicates do not mean for example: Helvetica, Helevetica Bold, Helvetica Bold Italic (these are three different fonts).
    You can reduce the quality of the graphics used and so on while in menu.
    The feature highlighted in green  more or less just reduce the general qaulity of the PDF. and may work for some PDF's

  • 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!

  • PDF reduce file size filters and CMYK to RGB conversion

    This doesn't seem to be on-topic to this forum, but I'm hoping someone here has the expertise to answer my question. We have some scripts which take a series of press-quality pdfs and use the "reduce file size" filter to prepare them for viewing on the web. We run these scripts on a 10.4 machine, and the filter works very well, reliably reducing file sizes of all sorts of pages.
    When we tried to upgrade the machine, we discovered that the quartz filtering has changed in 10.5 and 10.6. While it's usually an improvement, getting maybe 5-10% better compression ratios, it has become unreliable in that about 5% of my files fail spectacularly -- they blow up to 3, 4, 5, 6 times the original size.
    The other thing that happens is that the 10.5/10.6 filters munge the colors up. I found the solution to this -- in the ColorSynchUtility, make a duplicate of the Reduce File Size filter, and add a Color Management Component called Convert To Profile. This allows me to set a filter that converts the CMYK content to RGB. The problem is that there are about 40 choices of profiles, and it's not at all clear what I should use. Many of them have printer manufacturer's names in them, some say "Adobe", others have cryptic codes (probably referring to various RFCs and schemes). I've tried a couple of the ones that don't look like they are for printers, basically chosen at random. They all produce files of slightly different sizes for the reductions that go well, but on the files that blow up, some filters are better than others. (For example, I have a 5MB page which reduces to 1.4MB with the 10.4 filter, but blows up to 27MB with the "sRGB IE61966-2.1" profile, but only 12MB with the "Adobe RGB" profile.)
    So I have 2 questions:
    1) Is there any way to configure a 10.5/10.6 custom profile so that it behaves as reliably as the 10.4 "stock" PDF Reduce File Size works? It doesn't have to be the most wonderful compression algorithm out there, just so that it never or rarely has a file blow up in size.
    2) For converting press documents to pdfs that are going to go on the web, what is a good "Convert to profile" to use of the 40-some choices on the pull-down menu?

    Cathy,
    You have posted your question in a forum dedicated to the Final Cut Studio application Color. It is a very specialized program to grade (adjust) the color in video/film images. We know nothing regarding PDFs.
    Have you tried posting this on an Adobe support site?
