What file size is a PDF?

I receive lots of PDF files but I can't figure out what file size the creator used. If he used the smallest size setting, it wouldn't have a high enough resolution for professional printing would it?
I have preflighted PDFs but can't figure out where it tells me if a PDF is the smallest file size or Press Quality.
Thanks for your help in advance.

Sorry peeps but I have a question that is at the beginning stages but I seem to need to re visit this area, can anyone PLEASE tell me how to print to pdf. I usually hit command-p and go to printer and set my dpi to 300 and than check custom so that my postcard will fit correctly save to my designated folder and let Acrobat do the rest...the reason I go this way is because I have to keep my file size as low as possible because I have to email my files to the printer. is there a sight or can anyone please tell me what I'm doing wrong..I start with a file at 6.63mb and after I print to pdf with the settings I said at the beginning and I wind up with 51.23kb PLEASE help!

Reduce File Size and Optimise PDF both increase file size

Hi All
I have exported a pdf (our college mag) at smallest file size from Indesign CS4 for online use. The problem is the resultant file size is a little under 19Mb. Using both or either Reduce File Size or Optimise functions simply result in an increase to 22Mb. The document is packed with images however I would have thought one or both of these processes would have helped reduce the file size to a more manageable download file size.
A pdf is also produced to go to print so simply compressing all images prior to imcuding them in Indesign is not a preferable option - this would mean creating two separate Indesign documents, something which I would rather avoid if possible.
Any help would be greatly appreciated as always.
The file reside here if anyone cares to take a look http://www.ayrcoll.ac.uk/index.php?name=UpDownload&req=viewdownload&cid=11&orderby=dateD It's the latest release (September 09)
Thanks

You might want to do an audit of the PDF (button in PDF Optimizer) and try to figure out what the various parts are. It shows 58% is content streams (sorry, but I am not sure what that is), 26% is overhead, and only 12.7% is graphics. Since you are not storing bookmarks and such, you might want to try going back to ID and printing to the Adobe PDF printer for a comparison. It may be one technique is more efficient than the other.
When I used the optimizer, the file did get larger. When I used Reduce File Size, it got slightly smaller. The key may be in figuring out what the various parts are from the audit. You might try copying one page of ID to a new document and play with various versions - different fonts (all were embedded and that is probably best), variations on graphics, etc. That is all I can suggest since I would simply be playing with different ways to produce the document and looking at what is causing the bloat. When the Images are only 12.7% and the fonts less than 1%, there is something going on to produce the size, and those 2 are typically the killers. I would mention tags that tend to bloat, but you do not have any (normally used for assessibility).
You might want to try some of the preflight checks to find issues. I did the transparency check and got 170 instances in 22 pages. Flattening the page may help. There were some pages that seemed to be very bad. However, I did not get a big file size reduction. I did not get a lot of improvement by printing to a new PDF either. Certain pages seem to be part of the bloat problem. The print took a long time around pages 11 and 22.
One troubleshooting technique would be extract pages to separate files and look at the details of each page to see what is causing the issue.
Need to go. 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!

How do i reduce the file size on a pdf document?

How do i reduce the file size on a pdf document?

The only way to reduce the size is by editing the original document to reduce its size and then converting again to PDF.

How do you reduce file size of a PDF if Save As doesnt work?

I have been trying to reduce the size of a PDF, using the Save As > Optimized PDF method.
I have also tried Save As > Reduced Size PDF.
This is on a file made up of 20 pages of full page Jpegs. (These were generated by the script in Photoshop that generates Jpeg files from Layer Comps within the document.)
If I use Reduced Size PDF, I get a greatly reduced file size but the image quality suffers greatly. (Lots of artifacts and blurryness)
There are no options to choose the level of compression I want.
If I use Optimized PDF method, I cant seem to reduce the file size no matter what I set the Jpeg compression to.
Is there some way to cut the size of the file down but not lose so much image quality?
Any suggestions?

Part of the problem here is that the files that are produced when I run the script to output files from layer comps are very big.
If I "save for web" for each layer comp, I wind up with way smaller Jpegs. Thus a much smaller PDF.
So the question is: Can you make the script, Layer Comps to Files, create smaller more optimized Jpegs? (Like you get when you save for web)

How can I reduce the file size of a pdf when exporting?

I don't want to just choose between high quality print or smallest file size.
I want to export it from 60MB to 40MB.
Can I do this manually? When I use smallest file size the quality is too low and the content looks bad.
But high quality print exports my PDF at 60MB which is too big.

You cannot simply legislate the size of a PDF file. If you content is primarily text and vector, there is not much at all you can do to reduce PDF file size other than to cut out content. Otherwise, the only other variables are those of downsampling and compressing the raster images from your content.
You must be very careful in choosing the PDF export settings. The “smallest size” settings yield PDF files that realistically really are not fit for printing and may mess up any CMYK colors. The “high quality print” and “PDF/X-4” settings yield best print output, but yield the largest PDF files since they do less image resolution downsampling and only the maximum quality lossy JPEG compression.
I would recommend that you start with either the “high quality print” or the “PDF/X-4” settings and make a custom set of export settings. Assuming that you aren't going for offset or gravure printing, change the color image and grayscale image downsampling values from 300 and 450 to either 200 and 275 or no less than 150 and 225. If that doesn't give enough file size reduction, change the compression image quality from “Maximum” to either “High” or no less than “Medium.” Beyond these changes, you may end up with PDF files that will neither print nor display with any reasonable quality.

How do I reduce the file size of a pdf to email?

I have a 260 MB pdf file generated from Photoshop 6. I can't seem to reduce the size in Photoshop. Is there anyway to reduce the pdf outside of Photoshop? Thanks in advance for any help.

Hi Scott,
That's a pretty big PDF! You'll have to reduce it pretty dramatically to attach it to an email. But, you can use Acrobat to reduce the file size. Please see this video for pointers: https://acrobatusers.com/tutorials/how-to-compress-a-pdf-file
If you don't have Acrobat, you can try it for free for 30 days. For more information, see www.adobe.com/products/acrobat.html.

Reducing file sizes of multiple PDF's

Hello everyone,
I just got hired at a structural engineering company, and we are trying to go "paperless". I am in charge of scanning tons and tons of our old record drawings. We have an old scanner and the PDF's it creates are anywhere between 10,000Kb to 70,000Kb. After I scan every sheet, I am supposed to use the "Reduce file size" option in Adobe Acrobat. I am using Adobe Acrobat 7.0 Professional and I always make the files compatible with 5.0, which reduces the file size by 1/6 - 1/10. I've only been able to reduce 1 sheet at a time, which again, is time consuming. Is there a way I can reduce multiple files at once? I looked online and found an article here: http://help.adobe.com/en_US/Acrobat/9.0/Standard/WS65C0A053-BC7C-49a2-88F1-B1BCD2524B68.w. html, saying that in Adobe Acrobat 9.0, I can select "Apply to multiple" to reduce multiple files. Is there a way I can do it without upgrading?
Thank you in advance.

Unfortunately, it's not possible if you're using Acrobat XI. In previous
versions you can tell an Action to ignore non-PDF files but this feature
was removed in XI. Also, 35,000 files is way too much for Acrobat to
process. You need a more robust application for such a batch processing
task.

How do you minimize a file size in a PDF?

Help! I just need to minimize a file in a pdf- how?

You mean reduce the PDF file size? You need Acrobat for that; Adobe Reader cannot do anything like it.
Also, how much you can reduce the file size much depends on its contents. I have seen PDFs reduced down to 10%, others just by a few KB.
P.S. why do you need to reduce the file size?

A smaller file size of a pdf proof?

I'm working on a project for images in a 10"x13" book. I need to send a pdf proof of it to someone and the pdf file that I made is around 80mb. Is there anyway to reduce this when 'printing to pdf' from aperture so that the file size is smaller or more compressed?
Thanks.

Hi
You can use OSX built in quartz filters - see here;
http://docs.info.apple.com/article.html?path=Mac/10.6/en/8545.html
I used them to reduce an Aperture book to publish on the issu website and it worked very well.
You can get other tips by doing an internet search.

What file size is used for "optimized" upload/download?

When I upload my photo files from Aperture (and previously from iPhoto) I routinely use the upload setting named "dowloading of optimized" files. I know that this downsizes the files for faster upload/download, but still gives a file size acceptable for great onscreen presentation and for a resulting small print of someone downloads. Can anyone tell what downsizing Aperture/iPhoto does in this case? For example, 50% jpeg, email sized jpeg, etc. Since Apple will kill the MobileMe galleries in June I have to switch to another photo presentation host. For upload to such a host Aperture/iPhoto gives choices like 100% jpeg, 50% jpeg, etc. What I want to do is end up with something similar to what I now get with the "optimized" setting. Thank you.

You will note that I referenced both programs (iPhoto & Aperture) in my original message above, and I have posted in both forums. Since both programs offer the same (at least on the surface) option of "optimized" to MobileMe galleries, one might assume that both use the same or a similar system. Lengthly testing of my own is the "best" solution only if I can not find anyone who is knowledgeable about what these programs do in the upload. It has been my sincere joy over many many years that I often find people on these forums who possess knowledge much greater than I. As to the programs changing the algorithum at any time, I doubt that since this MobileMe function will disappear in June. Seems like a strange time to make changes.

What file size?

I want to export pics from iPhoto to do a slideshow in Final Cut Express. Does the file size matter regardless of where your show is being played, a T.V. or a 60' screen? My show will be played on a BIG screen and then DVD's made for T.V. What size should I export them as? Thanks.

'video' in FC/e has a max resolution of 1920x1280 HDef.
DVD is 720x480 pix, always SDef.
If you like to add 'Ken Burns'-effects to your stills ('camera movement'), resolution should be bigger for sure.
and, in case of a follow-up question: there's no such thing as DPI in video ...

Learn the file size of a PDF or other downloaded file?

How can I, with my ipad2, learn the size of a PDF file downloaded and libraried in iBooks? I need the information to decide how I'll distribute it to other users. Thank you.

Thanks guys for your prompt and quality information. In addition to using both your solutions I decided the best distribution mechanism was to load to Google Docs then email a link to my 17 users with download instructions and loading to iBooks. I hate to overburden mail systems with bloaty data. Thanks again to you both.

What file size and format show I ask someone to send me a movie in?

A company is sending me a movie which they filmed and edited.I want the full edited movie so I can just extract scenes from it.
What file, format and size should I ask it for in?
Or would it be better for me to recieve it as a Mini DV and recappture it on my computer?
I want the movie in as high quality as possible. Is quick time, 720x486, uncompressed, good? I don't want to sound like I don't know what Im talking about

What file, format and size is it originally and what do you intend to do with it once you have extracted scenes?
