How can I reduce the file size of a scanned PDF file?


It seems like a lot of folks are struggling with the size of scanned PDFs. Below are excerpts from two emails I received recently:

My [Fujitsu] ScanSnap makes PDFs that are too big . . . like around 60K per page! What can I do to make these smaller in Acrobat?

I have to eFile [with the Federal Court] and am having to split the filings into many segments to go through the [Court] gateway. The issue seems to be with documents that are scanned on our network scanner. PDFs produced directly from Word are a lot smaller. Is there some trick to reduce the size of scanned files?

Before covering how to reduce the size of scanned documents in detail, let’s discuss four factors that affect the size of scanned images:

Scanning Resolution
A scan at 600 dpi results in a much larger file than at 300 dpi. Color Space

Adjust your settings.

Leave as default, or fine-tune your settings as needed. You can switch to different aspects of your PDF (Images, Font, Transparency, etc.) by using the menu on the left side of the window. You can choose to not optimize specific aspects by unchecking the boxes next to each menu item. This can be useful if you want to optimize the text but leave the images unaltered.

When optimizing images, you can change color images to grayscale, compress, downsample, and lower the quality. When optimizing fonts, un-embed fonts that you know all of your readers will have. For example, if you are sending the PDF to people at your school, they most likely will all be using the same system to read it, so those fonts do not need to be...

I scanned some of my personal documents in PDF format on Mac. The files were big sized for any email attachment and so I started looking for some application or free solution to reduce these PDF documents. The first solution that was readily available on my Macbook was to use Preview.

You can open a PDF document in preview mode and then select File–>Export. In export dialog select Reduce File Size for Quartz Filter and click save. A PDF file will be created by the specified name in export dialog with a minimal file size. However the export is not good for use as it substantially reduce the resolution and hence was not a good solution.

Then i stumbled across another simple and free solution. You need to download the below given filters and copy it to the appropriate location as per your OS.

In the context of scanning a document to PDF, can ayone explain the difference between "output resolution (ppi)" located in the Advanced Document Settings and the "Image Quality" slider located in the "PDF Options" (as described by several people, including lions99 above)?

Are the two settings related (ppi vs. the image quality slider)? Are they independent of one another?

My general understanding is that a higher ppi will result in better resolution/quality of the scanned PDF (with a corrolary increase in file size). The way it's being explained, it sounds like the "Image quality" slider bar is being used for the same purpose (i.e. decreasing file size). I'm not sure of the interplay going on between the two settings.

Further confusing myself, I just scanned the same one-page document to PDF twice as a test - for both scans resolution was set at 200 ppi, but for one scan I set the "image quality" slider at "low" and the other I set the slider at "high." The...

Why Do You Need to Reduce Scanned Adobe PDF?

When you scan images through a high quality scanner, it gives you various options for saving the image file. You can save it as a jpg or a tiff, or you can convert the images directly into an adobe PDF file. However, the latter option has a drawback - usually the scanners process image files at high resolutions of 300 dpi or more, and the output images also have a correspondingly high file size. This makes it inconvenient to store or send the files over email, particularly if you have scanned a large number PDF pages. Even after converting the images into a PDF you still need to reduce scanned adobe PDF in order to decrease the file size.

Techniques to Reduce Scanned Adobe PDF

The main feature of a PDF file is that it looks the same, no matter in what program or on what platform is opened. While manipulating file size is not necessarily part of PDF creation software, you can plan, create and save your PDF using techniques targeted to minimize size.

Plan Your Attack

When you are planning a document to share as a PDF, consider steps to reduce the saved size of your document. Unless color is critical to the presentation of charts and photographs, consider using black-and-white or gray content only. PDFs can include objects, such as annotations, bookmarks, links and form fields, that add to the complexity of the file. Minimizing the use of these, or omitting them altogether, aids file size reduction.

Create the Original PDF

When creating your PDF file, you can include not only text, but also the actual fonts used in the original document, a key element of portability. You can choose among three levels of font embedding...

Lately, I’ve been trying to scan How To Convert Scanned Pages Into eReader eBook Format my class notes and handouts, and transfer some e-textbooks so I can view them on my Kindle to save myself carrying too much in my backpack. This is something that Calibre Calibre - Mighty eBook Management Software could help convert easily to ebook reader-friendly formats, but the resulting PDF files are often huge, have several pages and thus, take sometime to load and smoothly display things.
