What is image dpi after "Reduce Image File Size"

Does anyone know the resulting image dpi after using the "Reduce Image File Size" command in pages? My mother is trying to prepare some things for pre-press, and can't send her document to the printing press, because the pages docs are friggin huge! I'm trying to give her the easiest option for resizing all of the many images in the document, but don't know if this is a viable option if the end product needs to be printed. I need the output to be at least 300dpi.

As fruhulda wrote, asking Pages to apply changes to the pictures isn't the good path.
In fact, it's a perfect way to get a fat file.
My practice is :
Prepare the document in Pages to define the wanted size of every embedded pictures.
Edit the picture files in a tool dedicated to this task so that the resulting files will be 300 dpis ones for the wanted sizes.
Then, replace the original pictures by the definitive ones.
In most cases, the file will be lighter than the original one and you will have the 300 dpis resolution (except if you apply shadows but it's an other story).

  • How can I reduce the file size when PDF Optimizer does not do much?

    I have a PDF form that exists of 48 pages. 44 pages are forms / have form fields, the other 4 are just informative. Each form-page has approx. 80 fields (checkboxes, text fields).
    When I started setting up the PDF form the file size was 12 MB and I had placed fields on 21 pages. Then with 34 pages the file size was 19 MB. And with 40 pages it was 35 MB big! Finally with 44 pages the file size is 34 MB.
    So I searched with Google and found some tips. Using the "PDF Optimizer" option inside Acrobat for example. So I did, and the file was reduced only with 3 MB... 31 MB was the file. Also used the option "Save as.... Optimized".... no difference. I also found a suggestion about removing embedded fonts. Using the "Audit Space Usage" option I noticed the fonts taking many MegaBytes:
    * Content Streams: 5.287.000     15,09 %
    * Fonts:                24.556.810     70,08 %  !!
    * Acrobat forms:      3.349.164    12,05 %
    In the older PDF version (I saved and kept this one too) with just 21 pages with form-fields, the  "Audit Space Usage" shows:
    * Content Streams: 5.292.000     40,14 %
    * Fonts:                 1.290.224     9,79 %
    * Acrobat forms:      1.588.758    12,05 %
    So I could save many many MegaBytes by -UnEmbedding- fonts. But if I do this (unembed ALL fonts), the file size stays almost the same!?!?!? Why? What can I do to reduce the file size? I would like it to be 8 MB if possible (32 MB -  24 MB = 8 MB)?
    Thank you for your help!

    If you have authored the form, reduce the number of different fonts for the content and form fields.
    Any font used in a form field will cause that font to be embedded into the PDF.
    If you are going to Optimize the PDF be very careful with forms. Optimization does a lot of removal of items and rearranging of items which can really mess up forms.

  • Unsupported Image Format after opening a file in Photoshop.

    As from today,I am getting an unsupported Image Format after opening a file in Photoshop. I have made nothing more than as crop on the image. Why?

    Ernie, I misread your post indeed. I never saw a option to send RAW files to an external editor. All I can see is the option to chose what editor and then specify if PSD or TIFF is used. I always use PSD, usually 16bit and in one other installation in 8bit (due to RAM restrictions there).
    So Aperture creates the PSD version and PS edits that very version and saves it back into aperture. This is where I sometimes () get that "unsupported image" problem.
    I think this also is what Mike does: select a RAW master, use an external editor -> Aperture creates a PSD or TIFF. I haven't tried the TIFF option , though.
    My main point was: it all worked for a very long time and with the latest updates it is broken.
    have a good day.

  • Email-to facilitate emailing a photo by gmail or AOL, I reduce the file size.  Is it better to reduce the image size or increase the jpg compression?

    To facilitate emailing a photo by gmail or AOL and avoid overwhelming the recipient's screen, I reduce the file size.  Is it better to reduce the image size or increase the jpg compression?  I have been making a duplicate image of 35 MB and reducing the image size to 8"x12" at 72 resolution giving a file size of 1.4 MB.  Then I SAVE AS a jpg of medium compression giving a  file size of about 111 KB.  Overkill?

    Go to File>save for web.
    I usually make the long side 800 px
    At the bottom of the dialog, check "constrain proportions."
    At the top, select JPEG in the dropdown for the file format.
    All the work is done for you! 72px/in is ok for web work. 240-300px/in is the recommended range for printing.

  • How can I reduce the file size rendered by After Effects?

    When I render a relatively simple 5 second project in After Effects, the file size of the resultant .avi is 64MB.  If I change the properties to reduce the file size, the degradation makes the file unusable.  What am I doing wrong?

    Is AE's encoder really that inefficient? 
    The thing is, AVI doesn't mean much.
    It's pretty much an empty container box, which doesn't imply a quality level.
    So, AME could default to something completely different as a starting point to produce an AVI file.
    AE defaults to uncompressed video when you pick AVI as a format. So, obviously this produces huge file sizes. There could be similar quality thresholds with smaller sizes if you pick other AVIcodecs, but that's a different subject. And in any case, when you're rendering a production quality master,  file size is usually not your main concern. You typically use this high quality video file as a source for compressed flavors for distribution. So, pristine video files with huge sizes are a good thing - people then wonder why trailers at apple.com, for instance look so good. And the thing is, the most compressed formats benefit enormously from having an uncompressed file as a source.
    Regarding encoding efficiency, yes, AE is less efficient than dedicated encoding solutions. Above all, because it doesn't support 2 pass encoding. Note that for some formats, 2 pass makes a night and day difference, while for others, nothing as drastic as most users seem to believe.
    All of this is a moot point for AVI, because the default AVI codecs don't offer these encoding options, which are more the realm of distribution formats like FLV, MPEG-4/H264 or WMV.
    There are distribution codecs which use AVI as a container out there, but those are a different case.

  • Save as Reduced Size PDF and Save as Optimized PDF do not reduce the file size.  What gives?

    Save as Reduced Size PDF and Save as Optimized PDF do not reduce the file size.  What gives?  I used Acrobat 9 to do this for a long time.  I recently received new laptop loaded with with Acrobat 10 and it does not work the same.  I typically scan 8-10 pages of receipts, combine the files in Acrobat, and then optimize to reduce the size so I can upload with my expense report.  Typically, my files were reduced to 200-400 KB.  I have a 2 MB file that will not reduce at all.

    Bernd, thank you for your attempt to help but the option dialog windows do not contain the same options.  There are numerous other posts on this forum about this issue and there is no answer.  Clearly, there is an issue.  I have submitted this issue to our internal help desk.

  • Reducing song file size AFTER importing

    I now realize that I should have used the iTunes preferences to set the import file type and the quality setting BEFORE importing songs. However, I now have over 170 songs in my iTunes library, and I would like to be able to reduce the file sizes for those songs. I will change the iTunes settings before importing any more songs, but I would like to be able to reduce the sizes of those files that I have already imported. Some of them are as large as 6 MB, while most of them are around 3 MB. Both are too big. Is there any way to take care of this problem? I am particularly concerned about those songs that I imported from the iTunes store after paying for them. Songs that I imported from my CDs can be done over, but I don't want lose the money that I have invested on those songs that I bought from iTunes.

    Your answer reverses the usual order: it starts out with the bad news but then finishes with the good news...I think. I guess you're saying that nothing can be done with the songs I have purchased from iTunes. With them, I'm stuck with 3 MB for the usual 3-minute song. Well, so much for iTunes, then. I'll certainly never buy any more songs from them. That IS bad news. On the other hand, I think you're saying that I CAN convert songs I obtain from my CDs to smaller bundles. I used to do that quite routinely when I was in OS 9, but I'm not sure of how to do it now that I'm using OS 10.3.9. I hope it's not much more difficult, but I'll just have to see. Anyway, thanks for the information. Now I have to study OS 10 and the latest version of iTunes.

  • A simple and free way of reducing PDF file size using Preview

    Note: this is a copy and update of a 5 year old discussion in the Mac OS X 10.5 Leopard discussions which you can find here: https://discussions.apple.com/message/6109398#6109398
    This is a simple and free solution I found to reduce the file size of PDFs in OS X, without the high cost and awful UI of Acrobat Pro, and with acceptable quality. I still use it every day, although I have Acrobat Pro as part of Adove Creative Cloud subscription.
    Since quite a few people have found it useful and keep asking questions about the download location and destination of the filters, which have changed since 2007, I decided to write this update, and put it in this more current forum.
    Here is how to install it:
    Download the filters here: https://dl.dropboxusercontent.com/u/41548940/PDF%20compression%20filters%20%28Un zip%20and%20put%20in%20your%20Library%20folder%29.zip
    Unzip the downloaded file and copy the filters in the appropriate location (see below).
    Here is the appropriate location for the filters:
    This assumes that your startup disk's name is "Macintosh HD". If it is different, just replace "Macintosh HD" with the name of your startup disk.
    If you are running Lion or Mountain Lion (OS X 10.7.x or 10.8.x) then you should put the downloaded filters in "Macintosh HD/Library/PDF Services". This folder should already exist and contain files. Once you put the downloaded filters there, you should have for example one file with the following path:
    "Macintosh HD/Library/PDF Services/Reduce to 150 dpi average quality - STANDARD COMPRESSION.qfilter"
    If you are running an earlier vesion of OS X (10.6.x or earlier), then you should put the downloaded filters in "Macintosh HD/Library/Filters" and you should have for example one file with the following path:
    "Macintosh HD/Library/Filters/Reduce to 150 dpi average quality - STANDARD COMPRESSION.qfilter"
    Here is how to use it:
    Open a PDF file using Apple's Preview app,
    Choose Export (or Save As if you have on older version of Mac OS X) in the File menu,
    Choose PDF as a format
    In the "Quartz Filter" drop-down menu, choose a filter "Reduce to xxx dpi yyy quality"; "Reduce to 150 dpi average quality - STANDARD COMPRESSION" is a good trade-off between quality and file size
    Here is how it works:
    These are Quartz filters made with Apple Colorsinc Utility.
    They do two things:
    downsample images contained in a PDF to a target density such as 150 dpi,
    enable JPEG compression for those images with a low or medium setting.
    Which files does it work with?
    It works with most PDF files. However:
    It will generally work very well on unoptimized files such as scans made with the OS X scanning utility or PDFs produced via OS X printing dialog.
    It will not further compress well-optimized (comrpessed) files and might create bigger files than the originals,
    For some files it will create larger files than the originals. This can happen in particular when a PDF file contains other optomizations than image compression. There also seems to be a bug (reported to Apple) where in certain circumstances images in the target PDF are not JPEG compressed.
    What to do if it does not work for a file (target PDF is too big or even larger than the original PDF)?
    First,a good news: since you used a Save As or Export command, the original PDF is untouched.
    You can try another filter for a smaller size at the expense of quality.
    The year being 2013, it is now quite easy to send large files through the internet using Dropbox, yousendit.com, wetransfer.com etc. and you can use these services to send your original PDF file.
    There are other ways of reducing the size of a PDF file, such as apps in the Mac App store, or online services such as the free and simple http://smallpdf.com
    What else?
    Feel free to use/distribute/package in any way you like.

    Thanks ioscar.
    The original link should be back online soon.
    I believe this is a Dropbox error about the traffic generated by my Dropbox shared links.
    I use Dropbox mainly for my business and I am pretty upset by this situation.
    Since the filters themsemves are about 5KB, I doubt they are the cause for this Dropbox misbehavior!
    Anyway, I submitted a support ticket to Dropbox, and hope everything will be back to normal very soon.
    In the meantime, if you get the same error as ioscar when trying to download them, you can use the link in the blog posting he mentions.
    This is out of topic, but for those interested, here is my understanding of what happened with Dropbox.
    I did a few tests yesterday with large (up to 4GB) files and Dropbox shared links, trying to find the best way to send a 3 hour recording from French TV - French version of The Voice- to a friend's 5 year old son currently on vacation in Florida, and without access to French live or catch up TV services. One nice thing I found is that you can directly send the Dropbox download URL (the one from the Download button on the shared link page) to an AppleTV using AirFlick and it works well even for files with a large bitrate (except of course for the Dropbox maximum bandwidth per day limit!). Sadly, my Dropbox shared links were disabled before I could send anything to my friend.
    I may have used  a significant amount of bandwidth but nowhere near the 200GB/day limit of my Dropbox Pro account.
    I see 2 possible reasons to Dropbox freaking out:
    - My Dropbox Pro account is wronngly identified as a free account by Dropbox. Free Dropbox accounts have a 20GB/day limit, and it is possible that I reached this limit with my testing, I have a fast 200Mb/s internet access.
    - Or Dropbox miscalculates used bandwidth, counting the total size of the file for every download begun, and I started a lot of downloads, and skipped to the end of the video a lot of times on my Apple TV.

  • How to reduce jpg file size, not pixel dimensions?

    I am preparing images for the web and I really have 2 questions: one about gifs, and one about jpgs.
    My standard procedure is to reduce the image to the desired pixel dimensions at 600 dpi
    That gives me a crisp small image. then I either use it as is if the file size is low enough (I try for under 600 kb) or convert it to a gif with the save for web and devices tool.
    So here are my 2 questions (I will count this solved with either answer)
    1) When I convert to a gif I have the 4 boxes: one with original size, the other 3 with options but often the options are too low res for me How do I change my 3 options to start at a higher gif res?
    2) If I try to reduce the file size of the jpg in the image size box I set the resolution lower ( 400, 300), which lowers the pixel dimensions and the filesize, but I don't want to cahnge the pixel dimensions. And  If I reset the pixel dimensions back to the size I want them, even though it is a lower resolution the file size doesn't change. How to reduce jpg file size using only the resolution, not pixel dimensions?  PS I have tried messing with checking and unchecking the 3 little boxes( scale styles, constrain proportions, and resample) but nothing has worked.

    Gif is not a great filetype, especially if you want a crisp image. What are your pixel dimensions?
    For web, it makes no difference what the dpi is, only the final pixel dimensions so once you have that as you want, use 'Save for Web and Devices' and you can lower the quality - 100% being max and 0% being lowest. I wouldn't save anything below 55%. For a 600kb image, your dimensions must be rather big.

  • How to reduce folio file size

    This is a quote from the Adobe support pages:
    Default Image Format Choose a default option for the folio. Individual articles can have different Image Format settings. Choose Automatic if you want to let InDesign determine whether to export the pages as JPEG, PNG, or PDF. If you want to reduce file size at the possible expense of image fidelity and performance, choose JPEG or PDF. Choosing PDF lets users zoom in on pages that do not have interactive content.
    Our app is now 825mb and I am looking for ways to shrink it. We have used auto settings (presumably this means JPEG) at High. Our intention was to remake all the folios using PDF* to enable pinch/zoom (on pages that have no interactivity) but there is no way of telling what effect this will have on the file size since the PDF option offers no control over image quality.
    Can Adobe please clarify these settings.
      * We would have done this from the outset but for the fact that there is no desktop preview for this option.

    Thanks Ali
    Syncing audio to slide shows difficult, I have tried it. We do have quite a bit of video but also a lot of large stills and these are the ones that I am concerned about if rendering as PDF since there are no controls for altering the image quality within PDF folios. I am wondering what setting actually is actually used?

  • Retouch photo without reducing the file size/quality?

    I have been retouching some pictures for use in a photo book but notice that each time I do so, the file size decreases fairly significantly e.g from 4MP to 2MP.
    Is there a way I do minor retouching to a photo without reducing the file size/quality?
    Thanks in advance

    Where are you seeing this size reduction? What format are the original photos?
    For example when you edit a RAW photos you create a JPEG modified version which is much smaller - one I just did went from 17 MB as RAW to 4.4 as a JPEG  --  you could save as a TIFF but to me that is not worth the space loss - I seriously doubt that you will ever do anything that you can see the difference in quality between a TIFF and JPEG of yoru images

  • Reducing AI file size, without converting to another file type CS6

    I designed artwork for a large banner (84" x 32") so my AI artboard is that large. As you can imagine, with all the text and graphics I used, this file size is 22.8 MB. I need to email this art to the printer, but the file size is too large to email. How do i go about reducing the file size in AI so it still maintains large format print resolution? Will saving to a PDF lose the print quality? I'm at a dead end... help!

    For a 84" x 32" banner (vinyl, fabric/paper) a small amount of compression should be fine.
    I would start out with the high quality setting which gives you compression but at maximum quality 300 dpi.  this should make your 22.8mb file much smaller, (my guess without seeing your art is you have an image in there and will get under 10mb)
    If you need a smaller file yet,  go down to 200 dpi (change top 4 values to 200) and max to high quality to make the .pdf even smaller, and for a medium sized banner as you have that would look very good and you would have to look hard to see the difference, at a distance would be unnoticeable.

  • Reducing the file size Pages

    I am trying to reduce the file size of a document in Pages. It has many jpegs. When I use File>Reduce File Size or Format>Image>Reduce File Size, I get stuck at "Determining potential file size reduction ..." and it will go no further. Selecting "Cancel" or "Reduce" has no effect. I need to to a forced quit to get anywhere. Thanks

    To use the Reduce file size isn't the best way to do it but the easiest if it works. You probably have an image clogging the process.
    Instead reduce the image sizes in a graphical application suited for it. Do the cropping of the images first if you haven't done that already. Then down size the resolution to about 300 dpi if you want to print the document images. If it is only going to show on the screen you can down size the images to about 75 dpi.
