Does Preview compress PDFs when saving?

Hi.  My scanner can group separate scans into a single PDF on its own, but it is significantly slower than scanning documents separately and merging them with Preview. 
Since scans are essentially saved twice when going the "merge with Preview" route (once when scanned, again when merged), I'm curious to know whether Preview compresses PDFs with each save.  If so, I'd like to know how lossy this process is.  Anyone know?
Thanks in advance for any help / info!

  • Using Fields from PDF when saving

    Im looking on how to use fields in a pdf form when saving the form.
    ex. Incident Report
    Staff open up the form. Put in the information. Want it so when they save it puts the clients name and date in the save as. So they open Incident_Report.pdf when they save it would be Incident_Report_ClientsName_Date.pdf Yes the staff could type that in that way but want to make it as easy for everyone involved.

    So let's say you have the following fields in your file:
    Incident_Report
    ClientsName
    Date
    You can then add this code to the file's WillSave action (under Tools - JavaScript - Set Document Actions):
    var newFileName = this.getField("Incident_Report").valueAsString + "_" + this.getField("ClientsName").valueAsString + "_" + this.getField("Date").valueAsString + ".pdf";
    app.response("Please copy the text below and use it as the new file-name:","", newFileName)
    Of course, you can adjust the message to the user, and even the format of the file-name, although I've used the format you specified.

  • Does Preview support PDF JavaScript?

    Due to a PDF vulnerability, various security experts are suggesting turning off JavaScript in Adobe Reader. I don't see any way to do this in Preview. Does this mean that Preview does not support PDF JavaScript?

    From this link:
    -=-=-=-
    "There are exceptions. Preview can't open protected PDF files, and it may not render all PDF documents properly. The PDF file format has become extremely complex over the years, including support for JavaScript, embedded Flash content, and other advanced options. Acrobat includes far more extensive controls and content capabilities than simply printing to PDF, especially if you need to manage image resolutions and formats. Of course, this complexity in Reader and Acrobat is where a lot of these security problems come from in the first place.
    Since there is no risk unless you open a malicious file with Reader or Acrobat, one of the best steps you can take to limit the chances of future issues (aside from staying up to date with patches) is to set Preview as your default reader. Not that Preview is perfect, but we have yet to see it face the same number of zero day vulnerabilities or exploits."

  • Preview deletes info when saving a pdf form from the IRS

    This is driving me CRAZY. I have been working on my tax forms which have all been saved from the internet as a pdf through preview. When I go into the file to update numbers and try to save the file  with the updated information, it won't let me. It will only let me do a "save as". If I do a "save as" and name the file the same as before (replaces original) or if I rename it, the pdf will save, but any data that I did not type in in the most recent session is deleted. So, when I open up my taxes and change a few numbers, the new numbers are saved, but all the rest of my data from before is deleted. It is making me want to scream. It does this repeatedly to different forms saved from the IRS' website and my local state's revenue website and on different days and with a shutdown in between. It isn't the websites, it is preview! 
    Oh, and just for info, sometimes preview will let me save the data I have updated and I don't lose anything, but then I can make a couple of more changes, go to save and the ability to "update" my current file with "save" isn't highlighted, only the "save as".
    This is a brand new macbook pro, only a couple of months old. It has Preview version 5.0.3. I have done all updates that the computer has downloaded.
    Any ideas anyone?
    Thanks,
    Kristie

  • Name of PDF when saving

    Hi,
    I created a pdf and display it in WD4A. Everything works flne but when my users want to save the PDF locally with the standard adobe save button, the file name by default is "F.pdf".
    Thats in deed not a very meaningful name and I asked myself where it come from.
    But what I would like to ask you guys is whether and especially where and how i can set the PDF name for saving.
    In the best case it would automatically get the e.g. something like this "[invoicenumber]-[customer]-[currentdate".
    I have neither found anything in the parameters of the function moduls i use nor in previous post.
    Thanks!

    Hi,
    yes, I will try today or tomorrow to find a corresponding method in ABAP for such an byte stream operation.
    Your suggestion made me thing about it and maybe I also find a good hint in "offline forms" if I cant implement it in ABAP like you did in Java. Maybe Java is more powerful than ABAP. Wanted to learn it already but could never get an understanding how these WD-Java components get transported and how the whole stuff needs to get setuped with the development environment etc... But maybe I should rethink about it, looking at all the possibilities WD-Java offeres.

  • Older LaserJet printers compress PDF when printing

    When I print a PDF to both a newer (LJ 4250) and an older (LJ 4m) LaserJet, the older LaserJet compresses the PDF vertically, even though page scaling is turned off.  I'm trying to print a PDF of data onto a preprinted form, and the compression is causing alignment issues.  Thoughts or solutions?

    It might be your printer settings rather than adobe reader. When you get the dialog box up have a look at the prefernces next to your printer selection and make sure they are what you need. E.g. if your printer thinks it's printing out on a different paper size it my change the dimentions of the print out.

  • "Message Processor" does not get assigned when saving the document.

    Hi folks!
    When creating a support message (SLFN) and saving the document usually the BP of the current user got assigned to the partner funtion "message processor".
    This used to work but does not anymore. Now I cannot find the reason why.
    I think I could achieve this via customizing "Make Settings for Change Transaction Types" and using "Specify Copy of Current User" but I am pretty sure this was not customized before.
    I could use partner determination procedure, too. Access sequence "User" but still I am not sure this was customized before.
    I am using SLFN transaction type service provider scenario (SLFC0001)
    Anyone got an idea?
    Thanks in advance.

  • Explain Compression Options when Saving as TIFF

    Adobe PhotoShop CS5 offers three options for convertion of a RAW file to TIFF (LZW, ZIP, and JPEG).
    I would appreciate if someone can help me to make sense of the following.
    I do not understand which of these employ the "run-length encoding" scheme that should make the TIFF
    file much smaller than the RAW file.  I  have used all three types of compression but the only one that
    resulted in a subtantial reduction in size was the JPEG compression.
    The TIFF file with no compression is actually twice the size of the raw file.
    What are the LZW and ZIP compressions actually doing?
    Thanks

    How did you arrive at the conclusion that the tif should be smaller than the RAW-file?
    jpg is a lossy compression, so best avoided uo until the final output.
    As for lzw and zip (from the Help):
    LZW (Lemple-Zif-Welch) Lossless compression; supported by TIFF, PDF, GIF, and PostScript language file formats. Most useful for images with large areas of single color.
    ZIP Lossless compression; supported by PDF and TIFF file formats. Like LZW, ZIP compression is most effective for images that contain large areas of single color.
    So image-noise for example can negate all savings and I think zip with 16bit is a problem.

  • Does iOS modify images when saved to camera roll?

    As in, if I save an image from gmail so that I can then upload it to Dropbox, will that resulting image file still be the same raw uncompressed image as if I did it directly on a PC?
    This has been a big concern for me for years, I've always avoided it by using RDP when I need to save a picture I want to keep.

    Should I ask this under iPhone instead? Or perhaps there's a better forum to ask?

  • Why does Illustrator not remember filepaths when saving ??

    Hi,
    I'm finding it really frustrating that Illustrator 10 (on iMac G5 OS 10.3.9) does not remember filepaths when saving.
    Perhaps I've overlooked a setting somewhere.
    Does anyone know how I can rectify so Illustrator defaults to the last used filepath (as does almost every other program on earth) ??
    I'd be very grateful for any help.
    Thanks in advance.

    Can anyone tell me why this is happening?  Am I not saving this correctly?
    Well, to what format are you saving? The native AI format should always retain layers. Other formats such as EPS or older PDF Levels may indeed enforce flattening. also make sure you are not confusing layers with groups/ objects. There's a crucial difference between the two.
    And even more important, is there any way of restoring the different layers once this has happened?
    Well, you can manually add new layers and drag&drop your objects and groups into the new layers in the layers panel, but if you save it again to the wrong file format, that is wasted effort, so for the life of it make sure you get that figured out first.

  • Chinese characters copying incorrectly when saving pdfs with Preview

    So this is a very strange problem. When I save a .pdf that I have annotated in Preview, it saves fine and everything continues to display correctly. However, if I then try to copy Chinese characters from the pdf, it pastes gibberish. F'rex:
    灿烂辉煌 becomes "3456"
    and
    遇到的问题 becomes " !"
    Does anyone know what is going on and how to deal with it?

    The strange part is that initially the Chinese characters copy fine. It's only after I save the .pdf that copying goes all wonky.
    I think there is a bug related to annotation.
    Is there any way to control what encoding Preview uses when saving?
    No. PDF is the worst possible format to use for any kind of editing.
    Have you tried Adobe Reader? Or Skim?

    Preview is not always the best option.
