Re: File Compression

[Rick Armstrong]

Hi Clive,
I was going to suggest that first off but I wasn't sure if you had InDesign and 
some of the replies were quite informative. I can't understand why Adobe 
Acrobat can't keep reducing the original pdf, it just seems to do it once and 
then thats it.

 Hi Clive,
 
 The effectiveness of compression of a PDF will vary wildly
 depending on the content. Large PDF files normally contain a
 large number of images or a few very large images. If you have
 access to the source of the PDF you can choose to compress the
 images at a lower resolution and thus cut down on the size
 dramatically. You can also purchase tools which will compress  
 the
 images in a PDF even if you do not have the original source
 document.

You got in before me with this one Merv. PDFCompress is worth every penny. It 
performs better compression than Quartz, with a higher quality result. I would 
typically expect a 13Mb PDF to compress to around 3Mb, with little or no 
perceivable difference from the original using this utility.

Highly recommended.

Re: File Compression

Hi Guys

I have just tested a 1mb PDF in preview and it reduced it by two thirds, so 
export, format PDF, then use the Quartz filter to reduce size.  Of course it 
will depend on the PDF you are using and your mileage will no doubt be 
different.  The best option is to go back to the original and work on it there.

 Hi again Clive,

 I remember using it a long time ago and it did significantly reduce
 the size of a PDF file.
 
 "ColorSync Utility.app" From finder select the "Go" menu, and
 select Utilities.
 In this folder you will find the ColorSync application.
 
 1. Open ColorSync.app
 2. Go to the File menu and select open. Find the pdf file you want
 to shrink and select it.
 3. You will see the first page of the pdf file in a 'preview
 window', and at the bottom of the window you will find a drop down
 menu with "Filter" by the side of it.
 4. Use the drop down menu to select "Reduce File Size", and then
 click "Apply".
 5. You can then close and save the document, which will now be a
 smaller size.

 Compression works principally by finding patterns of repeated bits
 and replacing them with an copy of the pattern and a count of how
 many times the pattern is repeated. So a file with a lot of spaces
 in it, or an mp4 video with large areas of the screen all the same
 colour will compress down very nicely. However, if the file you
 are
 trying to compress contains little repetition such as an
 executable
 program file, then you will get very little compression.
 
 What was the file you were trying to compress?

 Hi Clive,

 Just adding to Carlo's comments.

 Open the PDF in Preview and then save it (as a PDF) again; the
 resulting file will usually be significantly smaller than the
 original with no difference in quality.

 Preview Save dialog includes, in the Quartz Filter pop-up menu, a
 Reduce File Size option.
 However, this option uses compression, so it reduces the quality
 of images and text in the resulting PDF.
 If you simply re-save a PDF, without this option, no compression
 occurs.

 How does this work if Preview isn’t actually compressing images?
 The program is simply using OS X’s built-in PDF-processing
 features to strip PDF files of all the unnecessary bits: preview
 images, metadata, and the like.
 This feature is especially useful for PDFs created in Adobe
 Illustrator and InDesign, which tend to be unnecessarily large
 because of program-specific components and other non-vital data
 these applications save inside each PDF.

 Ronni

Re: File Compression

[Daniel Kerr]

Just to weigh in.
Did the pdf come from something you'd "made", ie was it a pdf with photos that 
came out of Microsoft Word, or something similar?
Was it made from choosing "Print to PDF" from an Application?
Sometimes you have to go back to the "source" and then work forward to get the 
smaller pdf.

Kind regards
Daniel

Hi Clive,

Yes I find that Preview App will often increase the size of a PDF, particularly 
if you do some editing or highlighting. I avoid saving from Preview except as a 
last resort.

Depending how important this problem is to you, here is one of the paid apps 
that I mentioned that will compress the PDF for you.

 Hi Clive,
 
 The effectiveness of compression of a PDF will vary wildly  
 depending on the content. Large PDF files normally contain a  
 large number of images or a few very large images. If you have  
 access to the source of the PDF you can choose to compress the  
 images at a lower resolution and thus cut down on the size  
 dramatically. You can also purchase tools which will compress the  
 images in a PDF even if you do not have the original source  
 document.

 Carlo

Hi Ronnie

We will try ColorSync, we did as suggested using Preview but it  
doubled the file size??

Re: File Compression

[Ronda Brown]

Hi again Clive,

I forgot about using ColorSync Utility. If Preview does not reduce the PDF 
enough try ColorSync Utility.
I remember using it a long time ago and it did significantly reduce the size of 
a PDF file.

"ColorSync Utility.app" From finder select the "Go" menu, and select Utilities. 
In this folder you will find the ColorSync application.

1. Open ColorSync.app
2. Go to the File menu and select open. Find the pdf file you want to shrink 
and select it.  
3. You will see the first page of the pdf file in a 'preview window', and at 
the bottom of the window you will find a drop down menu with "Filter" by the 
side of it. 
4. Use the drop down menu to select "Reduce File Size", and then click "Apply". 
 
5. You can then close and save the document, which will now be a smaller size.

Cheers,
Ronni

 Hi Clive,
 
 Compression works principally by finding patterns of repeated bits  
 and replacing them with an copy of the pattern and a count of how  
 many times the pattern is repeated. So a file with a lot of spaces  
 in it, or an mp4 video with large areas of the screen all the same  
 colour will compress down very nicely. However, if the file you are  
 trying to compress contains little repetition such as an executable  
 program file, then you will get very little compression.
 
 What was the file you were trying to compress?
 
 Regards,
 Carlo

Re: File Compression

[Ronda Brown]

Hi Clive,

Just adding to Carlo's comments.

Open the PDF in Preview and then save it (as a PDF) again; the resulting file 
will usually be significantly smaller than the original with no difference in 
quality.

Preview Save dialog includes, in the Quartz Filter pop-up menu, a Reduce File 
Size option. 
However, this option uses compression, so it reduces the quality of images and 
text in the resulting PDF. 
If you simply re-save a PDF, without this option, no compression occurs.

How does this work if Preview isn’t actually compressing images? 
The program is simply using OS X’s built-in PDF-processing features to strip 
PDF files of all the unnecessary bits: preview images, metadata, and the like. 
This feature is especially useful for PDFs created in Adobe Illustrator and 
InDesign, which tend to be unnecessarily large because of program-specific 
components and other non-vital data these applications save inside each PDF.

Cheers,
Ronni

Re: File Compression

Hi Clive,

Compression works principally by finding patterns of repeated bits and 
replacing them with an copy of the pattern and a count of how many times the 
pattern is repeated. So a file with a lot of spaces in it, or an mp4 video with 
large areas of the screen all the same colour will compress down very nicely. 
However, if the file you are trying to compress contains little repetition such 
as an executable program file, then you will get very little compression.

What was the file you were trying to compress?

Regards,
Carlo

File Compression

Hi

OSX 10.4.11 g4,

Trying to compress a 37mb file using archive does not compress the  
file , turns it into a .zip but the file size is the same size. What  
am I missing.
