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.

Why can I only "Save as Other... Reduce File Size" a single time for an Adobe X file?

We are struggling with our form editing in that anytime we make a change and save the file size is doubled. As a work around we started using the ...Reduce File Size save as. However, we can only use that once per file. Some of our forms contain several hundred fields that are edited, with the behavior as is we cannot save our work as we go.
Reproduction Steps...
1. Open a file in Acrobat X and note it's file size.
2. Make any kind of change (our work is focued on View>Forms>Edit)
3. Go to File > Save as Other... > Reduce Size PDF
4. Set Version Compatability to 'Retain Existing' and Save
5. File size should be very close to the original
6. Open the new file
7. Rinse and repeat steps 2 and 3
8. Note that when you go to try to Save as the new edit, the Save As Reduce size is grayed out and no longer available for seslection.
Please help!!!!

Just do a standard Save As. The problem is that Save includes the old and new. Save As deletes the old. Also, if you distribute the form it is locked from editing as I understand it.

No option to "save as" PDF to reduce file size in Preview

There is no Save As option. I have tried exporting my pdf, there is no file size option when I do this. I have tried to duplicate the pdf as suggested in another topic on this forum, which also then didn't have the Save As option and also didn't have any file size options when trying to save in all the many ways which I had already tried. I also tried to print and save from there, which was another option suggested on this forum. That also didn't offer me any options to reduce the file size despite it being a "save as" window. I'm lost. Send Help.

The screen capture won't let me snag the dropdown selection (attached) but the only options available to me are...
Photoshop (*.PSD;*.PDD)
Large Document Format (*.PSB)
OpenEXR (*.EXR)
Photoshop Raw (*.RAW)
Portable Bit Map (*.PBM;*.PGM;*.PPM;*.PNM;*.PFM;*.PAM)
Radiance (*.HDR;*.RGBE;*.XYZE)
TIFF (*.TIF;*.TIFF)

How do I reduce file size in Preview?

how do I reduce size in Preview? Tools > Adjust Size is greyed out. I have a scan of receipts at 300 dpi that's 5.3 MB. I want to reduce for e mail.

I did go back and saved to .jpg and got an option to determine the quality and settled for 225 KB image. That works and it looks fine.
Unfortunately, though I clicked correct answer on your post - it looks like its giving me credit. I tried to undo, but I can't.

Compress PDF vs. Reduced File Size Quartz Filter?

Sometimes the PDFs I produce through the print function get pretty huge.
In the PDF drop down on the print menu there is a compress PDF option that I sometimes use.
Then someone said I should go to print, to the copies and pages, select "colour sinc" and on the Quartz Filter select "Reduce File Size" then hit the "save as pdf" on the pdf button.
I have no idea what I just typed
What's the difference between the two approaches and which would produce the best quality PDF at an manageable size?
I just tried PDFing this page using the three options -- regular pdf, compressed pdf and that colour sink / quartz filter / reduce file size. Damned if the smallest file isn't the regular (at 76 kb) next is the reduced (92kb) and the largest file is the compressed (140kb). Maybe not a proper test but what the heck?
Any thoughts?
Thanks

I believe that the same filter is applied no matter whether it is done through the Compress PDF button, which is an Automator action, or using ColorSync.
If you would like to experiment with it, you can also apply it through the ColorSync Utility. If you copy the Reduce File Size filter, you can change the amount of reduction done. You can preview the results there, too.
The filter only affects images, not text.

I have to zip pdf files to email them to someone with a PC. The problem is they aren't smaller after zipping and I can't email them. I tried adjusting the Quartz filter to the Reduce file size. Now they're smaller, but the recipient can't read them. Help!

I need to zip pdf files to email them to a PC user. The problem is file size is not reduced.
I tried zipping them in Win 7 (which I use via Parallels 7) and sending them to the Finder to email.
But lately nothing is reduced. I tried choosing the Reduce File Size option in the Quartz Filter when I save the doc. The file size was reduced. However, the recipient could not read the file. Everything was blurry.
Is there a solution?

I am having some PDF sizing issues also, I am a BETA tester for TurboCAD Mac, and with the usage of (public) version 5, I have had some scaling issues. I have had (auto sent) 15 plus crash reports, (available as text) and had posted my scenario within the "lion- problems so far" article, so not to use up extra bandwith- or whatever- there are pictures there. I was not able to upload a PDF on site, and the staff @ Turbo CAd is working on it also. this is Lion specific new update, as I have posted many large format PDF's

How to reduce image's file size in Preview?

I am in Preview Version 5.0.3 (504.1). I have a PDF file that is 3.7 meg. in size. That is a big large for what I want to do with it. I would like to reduce its size to something a bit more manageable.   The Preview Help gives these instructions:
To reduce an image’s file size without changing its dimensions:
Choose Tools > Adjust Size.
Select “Resample image.”
Enter a smaller value in the Resolution field.
My problem is that in my open window for this file the "Adjust Size" tool is dimmed. I cannot choose that tool as instructed.
Does anyone know why and how to get Preview to reduce the size of a PDF file?

try File-Save As...
& choose format:pdf    quartz filter:reduce file size
pick another name to check the results - there's no undo

Reducing file size by changing the photo size?

I inherited a bloated pages file with some photos over sampled at 14Mb+ Probably should be about 500k.
I want to open the file's package contents and edit the images using graphic converter. So far my attempts have resulted in the physical size reducing on the page. Anyone with a tip to reduce the resolution of the photo with out the result shrinking on my layout?
thanks

Well to answer my own question
1) for PDF files–open in preview>>save as>>select quartz filter- reduce file size.
2) for tiff/jpg open in image editor and change the resolution. Save as to NEW location.
in pages select the image and under format>>advanced menu "set as media placeholder" drag new image to this place to replace. TIP drag the icon in the title strip at the top of the saved file instead of locating in finder.
NOTE: for 2 if the image has been masked the pages image will need to be resized.
Of course this only works if the placed images have high resolution to start with or have been shrunk in the pages layout.
I had a 120Mb 5 page file that is now under 10Mb

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?
Good luck,

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!

Reducing file size #1...what exactly does file, reduce file size do?

Questions on reducing a pages to pdf file size…I will post each question seperatly.
1) I was surprised to see page reduce file size take it from 50 megs to 20 megs…when I looked at a large jpeg file, its size went form 230k to 70k, but the entire image (not just the visible part after the mask) was there (I was hoping it would crop to the mask).
I am curious, what exactly is reduce file size doing?
Is it applying a quartz filter that I can control through colorsync (I think not)?
Thanks, bob

You will need to test the results, but I suspect it is definitely lowering the resoltion to either screen resolution (72dpi) or double (150dpi) and upping the compression of the .jpegs.
In contrast to the Quartz filters, the results from file reduction in Pages is disappointing with a hefty loss of quality for not so much file reduction.
I would work with known distiller settings in Acrobat Pro for a better result.

Reduce File Size Help

Hi
Would any experts out there know how to adjust the default setting of "Reduce File Size" function? I thought it was linked to the default Colorsync "Reduce File Size" Quartz Filter but I found that changing that filter only effect Save As PDF functions.
I've been googling around without much luck.
Thanks in advance.
John

Peter is right. If you want to reduce the size of a PDF you can use ColorSync to create a PDF setting that reduces the quality (and thusly the file size) of the pictures in your document. In fact, Apple's already done this for us - Pages has 3 PDF export choices. But this has nothing to do with the file size of the Pages document itself. Your best bet is to use photo editing software to crop and resize the photo before you put it into the Pages document.

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!

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?

Reduce File Size doesn't work!

When I click the (new) option 'Reduce File Size' in Keynote '09 the app prompts a estimated new size which is smaller than the current size. When I click on 'Reduce' the app doesn't do anything except for showing an error report which tells me something like: "..the file size was not reduced", for all of the files included. They are just regular .jpg/.png and .psd files. Did anyone else notice this bug..?

I'd say if it is a very large file with multiple large images, it might not be actually freezing, just taking its sweet time.
It's why I leave Activity Monitor running when I use iWork applications.
This way, I know ifd the app is dead or if it's heavily busy.
Either that or it has nothing to do. It trims and reduces the resolution of bitmap images to 72dpi. There will be a fair bit of work if you have transparency in the document.
It doesn't do a very good job IMHO and to reduce the file by 90% is a big ask.
The 'Reduce FileSize' feature isn't linked to the 'export to PDF' feature.
As explained, before applying "Reduce file size" it's good practice to "Reduce Image File Size".
This will drop the parts of the pictures which aren't displayed.
The asked task doesn't imply a reduction of the pictures by 90%.
As I already wrote several times, it's more efficient to crop images to the really used area *_before inserting them in a Pages document_*.
A Pages document is huge by nature because the Index.xml file describing its contents is highly verbose.
If the document was saved with the 'embed Preview.pdf' feature active, the size of this PDF is adding a lot of used space.
I'd print to pdf and reduce the quality in Acrobat Pro.
Most of us don't own Acrobat Pro.
I feel that it would be a bit silly to buy an application whose price is : 450$ as a complement for a 80$ set of applications.
Before doing that, I would
(a) crop pictures before inserting them
(b) try to enhance Pages behaviour for free installing enhanced PDF filters.
