PDF gaining file size when "optimizing"

I have a PDF that I'm trying to reduce the size of, the original size is around 6 MB, when I have "optimized" the size actually increased anywhere from 9MB to 15MB. There were a few attempts that I do get it to a lower size, but along with that there are missing letters and font issues. I've attempted numerous processes, but can't seem to find one that works. Any suggestions on a fail-safe way to do this? Any help would be appreciated. Thanks!

Getting rid of fonts is a bad idea if you are making it a web document. However, you could subset the fonts. You might also try FILE>Reduce File Size. There are a lot of options in optimize and you may need to play with those a bit. Bill

Nothing much. Different formats.

Try editing the original file. Resample pics to a lower resolution, check out other graphics, check table borders (eliminate any dotted lines or borders), check font usage. When generating PDF, try Save As (instead of Print > Save As), although I don't expect that'll make much difference.
Next, open the PDF in Preview, choose File > Save As, choose Format: PDF, Quartz Filterz: Reduce File Size. If that isn't enough, you can use ColorSync Utility to duplicate the Reduce File Size filter, and then edit it for a more aggressive size reduction. But keep in mind that size reduction means lower quality.

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,

Adding Bates numbers to PDFs increases file size by 10x - How to keep original size?

I have a lot of email texts that I converted from Word to PDF and then Bates numbered.
However, Bates numbering made each email's file size go from about 50kb to 500kb.
Once I combine these larger files for uploading to a docket, at the maximum allowable file size is 4 Mb, I can put together only 8-10 emails at a time. What to do to keep the original file size small when Bates numbering?

Hi paulu40695891,
Yes, there is a significant increase in the file size when one applies bates numbering to the pdf and saves it.
A workaround for this issue would be to save the pdf file again as reduced size pdf. (File -> Save as other -> Reduced Size PDF. )
Does that helps with your issue? Please revert back for any further query or assistance.
Regards,
Rahul

Yeah - I tried that, several times; each time I get "iTunes is restoring the software on this iPhone" and after about 30 minutes the screen on the phone lights up again with the same screen I had before. After that ... nothing.

File sizes when burning in different formats

Like many people, most songs in my playlists are MP3s/MPEG.
If I want to burn 20 songs as an Audio CD (to play in a car's CD player) and select same in Preferences>Advanced, I understand that the files will be uncompressed to something like AVI format.
My playlists show (at the bottom) file sizes of 50MB to 70MB. Obviously, the real size when uncompressed is something nearer 700MB. It means a bit of guesswork as to how many songs I can burn on one CD.
Similarly, when burning Data CDs, the file size will be much reduced.
Is there a way I can ascertain the exact file size when burning in different formats?

+"It means a bit of guesswork as to how many songs I can burn on one CD."+
For audio CDs, there is no guesswork required. At the bottom of the playlist that you are about to burn, you will see the number of songs and the total time. If the time is under 80 minutes, the list will fit on a normal audio CD. If it is approximate, like "1.2 hours," click on it and it will change to exact hours, minutes, seconds.

Export to PDF (smallest file size) is giving me a very large file

Hi all,
I got 2 document with around 100 pages (same size), with a picture or two in each page.
I've been using the Export to PDF (smallest file size) and export it.
first file became 5MB, which is fine
second file became 30MB, this is much too much.
I have used the exact same setting for both files and have no idea why the big difference between them.
The only difference between them is that first file contains CMYK photos, and second one - RGB.
Can this be the difference?
Any suggestions?
thanks,
shlomit

That's certainly part of the difference. Additional font information if one of the documents uses more fonts or additional glyphs could be some of it, too. Swatches and styles might also be a factor. Vectors don't compress like bitmaps, either.
Have you opened the optimizer and done a space usage audit to see what is taking up all the space? Did you do a Save AS before export?

I need to compress an InDesign file to web-quality pdf but file size is still too big. Help!

Hi Bill,
It sounds like your document has a lot of pages and/or images in it.
Instead of using the normal InDesign > Export command to create a PDF, you may be able to reduce the file size by printing to a PostScript file, then distilling it to PDF using Acrobat Distiller.

I print 2 pages to pdf and file size is 600k, I print 1 additonal page and file size goes to 6M, what would cause this (graphics are same on all pages)

I print 2 pages to pdf and file size is 600k, I print 1 additonal page and file size goes to 6M, what would cause this (graphics are same on all pages).
I know the colour graphic shading in the document that causes the issue of larger file size, but it doesn't make sense that printing 1 additional page with same information as first 2 pages would cause this.

Stop images from losing file size when scaled down?

Ive read this tutorial;
http://joedasilva.com/blog/?p=32
and ive just found out that if you scale an image smaller,
the file size is permanently decreased, and enlarging the image
again will make it pixalated. If im working with images and I want
a lot of freedom to play around with the scaling, do I need to
convert them all to grafics?
Is there a setting I can change so that the images are saved
at the display resolution when I export them, but maintain there
full file size when in the document? Is this how illustrator works?
thanks

There is no such a thing as a "grafic." In your Fireworks
document, you can have bitmap objects and vector objects. Bitmap
objects, such a photographs, are rectangular objects with detailed
information, where the color and transparency of each pixel is
specified. Vector objects are mathematical objects, where the shape
is determined by nodes and the color is determined by the fill
type. You cannot convert a bitmap object to a vector object
(although you can sometimes create a vector illustration that
resembles a photograph).
If you are still experimenting with your design, what you can
do is add a layer with your original-sized bitmap objects. Put this
layer at the bottom of your stack and keep it hidden. Then, anytime
you feel a need to refresh an object that you've resized too many
times, copy that object from your originals layer. It may not be a
perfect solution, but it should help you.
I've never had a problem with multiply resizing photos,
myself, because I design my layouts with vector shapes first. Once
I have all my proportions set,
then I add any photos I have. With this worflow, I know what
size to make my photos. Of course, I might change my mind, later,
but my process keeps me on track.

How can I keep tabs on the file size when importing from the Event Library into a Project? I want to ensure the movie will fit onto a 4.7Gb disc?

iDVD does not care about file sizes, as it compresses the file to the standard DVD format of mpeg2.
It only cares about length i.e. max 2 hours including titles etc.
iDVD encoding settings:
http://docs.info.apple.com/article.html?path=iDVD/7.0/en/11417.html
Short version:
Best Performance is for videos of up to 60 minutes
Best Quality is for videos of up to 120 minutes
Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
Professional Quality: The Professional Quality option uses advanced technology to encode your video, resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned abo
In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

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.

Acrobat 7.0.9: Optimizing PDF increases file size?

Audit Space Usage in the Optimize dialog shows "Color Spaces" ballooning from 0.8 MB to 22 MB when a PDF is optimized (goes from 3% of the file size to 58%). File size increases from 23.8 MB to 35.6 MB.
What exactly is happening, and how can I fix it?
Thanks for any info.

Hey, Jon
Interesting...
Original file (300 dpi CMYK images) 23.8 MB
Images 19 MB
Color Spaces 0.8 MB
Optimize with flattening (72 dpi images, low quality) 68.7 MB
Images 49 MB
Color Spaces 18 MB
Optimize without flattening (72 dpi images, low quality) 68.2 MB
Images 48 MB
Color Spaces 18 MB
Not sure why color spaces are down to 18 MB from 22 MB, I used a preset that I THOUGHT was the same one I used yesterday. Regardless, it's bizarre that both images and color spaces are getting huge when optimized.
I used Create PDF from Multiple Files to bring in a bunch of pages, but I'm reasonably sure that all those files were already flattened before I brought them in.
I'll file that transparency tip for next time though, you never know when it might come up.
Thanks.
