Exporting reducing file sizes

Im using a version of aperture 2 at the moment and i have noticed that when i export my jpegs at original size they are only coming out half the size into my destination folder - i shoot in HQ jpeg, original size straight out of camera is 5-6mb. When i import them into aperture they still show as 5-6mb in the metadata. Then when i export them - always at original size I have checked and checked this - they are reducing to 2-3 mb in the destination folder. In photoshop these smaller files are measuring approx 4000x3000 pixels and when i then save them as high res jpegs out of PS they are jumping back up to the initial 5-6mb. I am confused. Dont want to be doing any more destruction than i need to.

Check your export settings. When you see "JPEG - Original Size" as the export preset, that is just the title of the preset. Choose edit and see what the actual settings are for "JPEG - Original Size"
And I'm looking at Aperture 3 when I say that. Can't remember if it's the same with 2.

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!

Reducing file size in iphoto

I needed to free up disc space (I have over 6000 photos stored in iphoto). I couldn't find a solution in this forum, but have hit on a way that works.
1. Move photos to a CD to preserve original file size. 2. Export photos at reduced file size to a folder on the desk top. 3. Trash original photos. 4. Import reduced size photos. 5. Trash folder.
Reduced size photos are fine for viewing and 4x6 prints. Larger prints can be made from the CD.
Perhaps there's an easier way, but this works.

File -> Export
Note the Jpeg Quality setting. That has the most impact on file size.

How to reduce file size

I have one page file. There is no image, just text. Now the file size is 3MB.
I cannot reduce size anyhow. I have moved the tick from embed fonts at save option tab but file size is same.
How I can reduce file size?
In addition this file is used so many times.

Probably not.
If you don't see the Master Page tab in Designer, then the way in which you imported the existing PD means that the page was brought in as artwork. I don't think you will be able to reduce it now.
One potential option would be to:
Go back to the existing PDF and export the page as an image. You can process the image in Photoshop (or similar) and get the image file size down.
Then start a new form in Designer and on the Master Page drag on an Image object and associate it with the image in step 1.
Save this new form and see is the file size acceptable. If so, proceed.
Now open your existing 3Mb form in Designer and copy all of the objects.
Paste these into your new form.
You may need to move things around a bit.
Hope that helps,
Niall

Reduce file size w/o blurring up my images?

I have a Pages (iWork '09) document with a lot of images (screenshots) in it. Many of these are large shots where I've used the mask option to hide what I don't need. The file is pretty large, even when I export it to PDF. Using the Reduce File Size option turns my screenshots into a blurry mess. Is there are way to get rid of the cropped areas w/o mucking with the image resolutions? Most of the pics were screenshots from Evernote dropped into the Pages file.
Short of that, will exporting to PDF and using Adobe Acrobat Pro's file optimization do the trick w/o blurring things up too badly?

Thanks for that. I was hoping I had independent control of cropping. I'll just have to do the cropping manually and rely on masking for trimming out little bits of things. I'm coming to Pages after years with Word, which allows more control when it comes to dumbing down images. I really like composing things in Pages. Now I just have to learn the best ways to get quality output w/o huge file sizes.
Thanks,
Wheat

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.

Acrobat 7Pro - Reduce File Size

I make PDFs by exporting from QuarkXPress 8, using the "Screen - Low/ Quality/Low Resolution" option for proofing. When I try to "Reduce File Size..." in Acrobat, it re-writes the files but DOESN'T make a smaller file. Any suggestions? I hate sending 9mb proofing files to my clients.

If you have a file made from AutoCAD it is probably just line drawing. There is really no scope to reduce the size of these (except by taking away lines, which wouldn't be popular). I don't know why it gets bigger, but it's unlikely to get smaller, so I'd recommend finding a different way to deliver the file (many web sites exist for delivering large files).

Btach reduce file size within iPhoto interface

Fellow iPhotorers
Is it possible to bulk or batch reduce file size within iPhoto - i.e. without having to export then re-import the pics THEN delete the originals?
For example - if I have shot a bunch of pics at high res which I decide or worth keeping as small (low KB) jpegs and not 3MB camera originals.
Cheers
Russell

Russell:
Welcome to the Apple Discussions. Depends on what you mean by resize. Do you want to reduce the pixel dimensions, say from 2272 1704 to 800 x 600 keeping the same ratio of dimensions, and, thus, reduce the file size? Or do you want to keep the original pixel dimensions and reduce the file size, which requires a reduction in quality thru greater compression?

Undo reduce file size

Worked up documents on Pages with multiple photos, some at high resolutions. Reduced file size for emailing and sending to dropbox and now want to print in an 18" x 24" size. Sample print is very blurrry How do I undo reduce file size? Would exporting file via pdf (best file quality) help? Any other suggestions. Much aprreciated.

Hi Trudy,
Reducing file size works by reducing the file size of any high resolution images to 72 dpi, OK for on screen use, but quite pixelated if printed or enlarged. Here's an example:
Here's the original—This is a detail, enlarged to 400% on the screen, but reduced by the discussions software to fit on this page. Note the spider web below the frog.
Here's the warning you get when you choose Reduce File Size:
Note that it says it "replaces" the original versions of the images. Scarey thought, but not as permanent as it appears.
Here's the result:
The frog's snout is quite pixillated, and the web has almost disappeared, as has much of the texture of the frog's skin and of the rough-sawn cedar siding behind. Again, a 400% enlargement on the screen, with the reduction imposed by the discussions software.
If you act at this point, it is possible to undo the change—throwing out the edited image and replacing it with the original version. The option appears to remain available even after the document is Saved, but disappears when it has been Closed. That would make sense, as Saving both the reduced image and the full version would not result in a reduction in file size.
But there's one other factor: When you drop an image onto a placeholder in Pages, the image that is inserted is a COPY of the original image file. The editing referred to above is done with that copy, not with the original image file, which continues to exist, unchanged where it was before being inserted.
To get the hi-res version back, then is a matter of dropping the original file onto the placeholder again.
Seems to work.
Regards,
Barry

Reduce File Size causes images to be blurry

I created a document in Pages '09 that contains several masked images, resulting in a really large file size. I clicked Reduce File Size to get rid of the cropped parts of the images. Unfortunately, the images are now blurry. Any way to mask or crop a picture, or use Reduce File Size, without loss of image quality?

The images are being reduced to 72dpi with no sharpening that I can see and the excess image outside the masking shape doesn't seem to get trimmed. I suspect you then saved to a pdf with a lower quality setting which would have given a 2nd reduction in quality on top of the first.
So the best option is to take your images into Preview, crop them, reduce their resolution and sharpen them then bring them back into your Pages layout before exporting to pdf.

How to reduce file size when using batch processing?

I use File > Process Multiple Files to batch process photos to a smaller file size along with adding my watermark. I've played with many different settings and no matter what I choose, I can't get my average file size to be less than about 200k. However, when I've exported the same photos using iPhoto, I can get the file size to about half of that with no difference (to my naked eye at least) in quality.
I definitely want to keep the height at 768 pixels so that needs to stay constant.
My current settings in batch processing (average file size = 200 kb)
Resize images with a height constraint of 768 pixels at 150dpi
What I've tried:
Resize at 72dpi (reduced file size by about 5kb)
convert file to JPEG low quality (reduced file size by about 10kb)
convert file to JPEG medium quality (not much difference in file size)
I'm using PSE 10 on a Mac running Lion.
Thank you in advance for your help!

You should go with default settings of Optimizer.
One difference between default settings of Optimizer and Reduce file size is that Optimizer does not guarantee a reduction in file size (if your Optimizer settings lead to an increase in file size, that's what you will get).
With Acrobat 9, the default setting in Optimizer has an additional setting which would not do an image optimization that results in increase of file size. In that sense it would in most cases give a smaller file.

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
Colin

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.

Optimize/Reduce File Size

I'm working with a PDF that I did not create but have been asked to try to reduce the size of. It was created in InDesign CS4 (don't know if it was Mac or Windows). It is a large book (600 pages) but entirely text, other than one graphic on the cover. A similar book that I had worked on produced a PDF of about 2.8 MB. The one in question is over 6MB. Using the Reduce File Size command and using the Optimizer both increase the file size.
Auditing the space usage shows that 86% of the space is "Structure Info." I believe the InDesign file was done by someone not very versed in the ways of InDesign, and that there were many places where text was threaded in strange ways, with lots of overlapping text boxes. I don't know if that would have anything to do with the "structure info" in the PDF. "Structure Info" isn't even listed in the audit results of the normal PDFs I'm comparing this one to. The InDesign file was actually several InDesign files, and I don't know how the PDFs of the individual files were combined, but that's another piece of information.
Given the above facts and the little I know about how the PDF was really exported and assembled, does anyone have any ideas about actually making the file smaller? Based on the other PDFs we've done of simlilar books, it should be somewhere around 2.5 to 3MB in size, not the 6 to 8 it currently is.

Auditing the space usage shows that 86% of the space is "Structure Info."
It would appear that the PDF is a Tagged output PDF.
As discussed in ISO 32000-1, Tagged PDF facilitates content use/consumption by:
--| users of AT for Accessibility
--| users of mobile devices (reflow)
--| content export with format/layout information
--| simple copy/paste
If the PDF is, in fact, a well-formed Tagged PDF then the author actually has commendable competency with InDesign.
Oh yes, using Acrobat Pro you can use either Optimizer or a Preflight to remove all structure. This would help reduce the PDF's size.
Be well...

Reduce file size for posting

I am trying to upload some photos to eBay. The original file size ris under 5Mb in Aperture but eBay claims it's too large at over 9Mb (the max apparently is 7Mb).
Rather than bang my head again the wall arguing I'd like to reduce the file size even more to say 2Mb in Aperture but have no idea how to do this. Would changing the pixel vertical and horizontal count be an easier way?
I also have no idea how to do that despite searching Help yet again to no avail. I tried reduce photos, reduce file size, reduce pixels... nothing relevant came up.
Sorry for being such a clutz but I never seem to get anthing from help but you guys always come up with the goods.

You can look at the exported files in the Finder to see the size the size and you can tell if it really is to big or if something else is going on.
So how did you export the images you tried to upload already? What settings did you use? There are a few different ways to control file size and which to use depends on how you plan on using the images.
Assuming you're exporting as JPG you can drop the quality slider down that will definitely bring the file size down but again without knowing how you exported how much over the file really is and how you plan on using them it's difficult to get more specific.
regards

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.
