There is often a need reduce the size of the PDF document,which is already created. For these purposes, the easiest way is to use adobe program Acrobat (Standard or Professional versions). For example version Adobe acrobat 7.0 is now available for free download from the Adobe website (registration may be required). Please note that for these purposes the usual PDF viewer (i.e. Acrobar Reader) is not suitable! Needed exactly pDF editor documents.

For information. PDF file cannot be reduced if it is made of vector objects, i.e. for example from text microsoft applications Office (Word, Excel) or AutoCAD - because vector graphics always take up a minimum of space, unlike raster graphics. therefore this decision will help you a lot, most likely only when compressing scanned documents into PDF, i.e. created from bitmaps.

So, open the PDF file that you want to compress, go to the menu "File" - "Save as Other" and select the item "Reduced Size PDF File":

Next, you need to select the version with which the resulting compressed reduced PDF file will be compatible. The newer the version you select, the smaller the file size will be. But keep in mind that if you select, for example, version "Acrobat 10.0 and higher", the file may not open in version 7, 8, or 9, i.e. previous. But now most users use Acrobat Reader versions 10 and higher, so there should be no problems. And if not, then a newer version of the PDF viewer can be freely downloaded and installed.

By the way, this opportunity can be used if needed. reduce PDF size of multiple files at once!It is very convenient when there are many of them, so as not to open each separately:

After pressing the "OK" button - select a location to save the finished reduced PDF file,and give it a name. At the expense of some loss of quality, the document will take up less space than usual.

Having received today from a person whose abilities I do not doubt at all, and who is no stranger to computers and the Internet, a letter with an attachment of three scanned documents with a total weight of 38 megabytes,

i decided to tell him step by step how to reduce the scanned files.
And then I thought that, for sure, it would be interesting and useful to someone else.

And the link to this page can henceforth be given to people - without additional explanations - receiving from them multi-megabyte letters.
Like this:
"Yes, by the way, I came across a page on the network here, I think you will be interested: "

So. Let's get started ...
Warning: I think that most of my readers will not be interested in this entry and will not provide any new information.
Don't say I didn't warn you ;-)

0. Start withthat management programs for many scanners allow setting the quality and size of the output file, as well as its format.
In 99.99% of cases, you will have enough jPG format , size 1200 * 1600, DPI \u003d 300, in other cases: 2400 * 3200, corresponding to the size of A4 sheet
But, if it was not possible to configure in the scanner, then it is the guide below that will help us solve everything.

1. So, we have a file scanned from A4 page.
We put the TIFF format (or our not-so-new scanner refuses to save files in other formats, or it resets our settings every time, or it works quickly, only saving it to TIFF) - I have come across all the above cases and they are all defeated.
The resulting file is an eerie 26 megabytes.

2. Open it in IrfanView.
I recommend this program because I have been using it for viewing images for over 12 years. It's free for non-commercial use and supports many handy plugins. It is best to download it from the official website.

4.and choose the format - JPG

5. Setting the file quality 85% - in most cases this is more than enough, and this figure has a very strong effect on the final file size

7. You can stop at this, but if the file that we are sending will only be viewed on the monitor without printing, or printed without the need to save high quality, we can make the file smaller... It will take a minute.

We push combination ctrl keys + R or select "resize image" from the menu:

and reduce the size of the image:

After that, the "weight" of the file became very small compared to the initial one, less than 1 megabyte

We can finally stop at this.

I will add that depending on the goals, the size and weight of the file can be changed in a very significant range.
Experiment!
