Worked fine for me. Today, I just happened to have tried to save a 200dpi file as both a 100dpi and 150dpi file using PDFPlus but neither file was legible. With PDF Compressor Pro 3.0 the 120dpi file was still readable and the file size was reduced from 411KB to 187KB.

If you use the 'Send To' option from Windows Explorer, and then use the 'email' option, all images sent this way get reduced, and quality is still acceptable.

A picture reduce, Only scaned pictures, I use PDF regularly and do not create them by scaned. Yes I do scan items to add to a PDF and then create the complete PDF in the computer and send it by the net.

Number 14 - I would also be interested in your search program.
How can I get in contact

#3 & #14 XP-Man (and #13 Roland):

Did you manage to communicate on the "search" topic? Please see my entry under the forum category "Software Talks" on FileSearchy Pro 1.3 that I started (and reply, I hope) -- Thanks!

As a reminder, anyone can search this web site for prior reviews of similar software for compressing PDF files. PDFZilla themselves have generously offered many PDF-format-related applications since January 2009 (to see their prior titles, just click on the "Publisher" link in the box near the top).

Also, try a simple search of this site using their own feature:

...although I get more results searching the site via Google:

Ok the developers acknowledge the problem themselves and say that this program is not for mainly text pdfs, but for scanned pdfs. Have no need for this, especially when orpalis mentioned above manages to compress even a mainly text pdf to less than 50%

This software is a joke. It increased the size of all my pdfs, in some case from 2 Mb to 55 Mb. Why is that? - its because it converts everything to an image, including the text! So essentially an efficient text file gets converted in a inefficient picture. Deleted

Increased the file size of a largely text-based pdf by several times.

Worked as expected on an image based pdf. But at 120dpi, a mostly text-based pdf (help for Revo Pro) expanded from

2.79Mb to 16.9Mb - about 5 times bigger, not smaller.

This program uses customised Windows frames, so snap doesn't work, for example, nor utilities that rely on standard frames like FileBox Extender.

I found the 'Original pdf folder' confusingly named. For example, when I dragged a pdf in to the program, I somehow expected that to open its original folder.

Minor text issues:
Recommended/ recommanded on GUI (seen when clicking Default)
FileName should be File Name

Why the compressed PDF file is still big or larger?
=>Why is the compressed PDF file still big or larger?
Why the compressed PDF Pages are Blurring?
=> Why are the compressed PDF Pages Blurred?

In my job I have to scan in several receiver reports and email them to specific people. A lot of the times with the exchange server companies will set email size restrictions normally like 10mb or 25mb. In my case it's around 10mb as for restrictions.

I can't even start to say the amount of times I have had to decrease the quality of a scanned in image to make sure there is plenty of room.

However, while in theory and concept this program is useful and I'm sure somebody out here would find this user friendly I personally find it kind of pointless.

1) If I need to scan a document in it will auto become an image. I can choose to either save it as a pdf or as a .jpeg/.png. If it's a jpeg/png the file already is going to be about 100-500kb size by itself compared to a pdf which can easily be 2-4mb per page on a pdf with around 300-400 dpi.

What I will do a lot of times is change the dpi from 300 to 200 so that a 5-7 page receiver report becomes about 2-4mb. This procedure works great and is still fast to do.

Uninstalled and rebooted machine.

Tried compressing two pdf files, both resulted in a bigger size file.
Description of product states that it can also remove protection. Great, tried it, that doesn't work, or has no option to do it? Confused, but uninstalled anyways.

Any software that comes with the scanner can do auto compression, just go to settings and tell the resolutions in dots per inch, done.

#13 Roland.
Would be more than happy to oblige if you can find some way of letting me get in touch with you.

To #3 Xp-Man : Thank you for your contribution. Would be very much interested in your search program you are talking about. How would it be possible to get it?

#8 Thanks yet again mona.
Tried the program you suggested and it performed very well on a document containing text and graphics; it reduced the PDF file from 430 K to 210 K with minimal deterioration of the images.

Also tested the first selection in #4 Giovanni’s comment, no change in the file size, in fact no noticeable change in the document.

Now this is something I can use. In the past I have used a free online PDF reducer to make copies I can email, however, I dislike sending documents to the web even though they claim to be removed within an hour. Much safer to do it on my desktop.

i have to share PDF documents with my coworkers on a regular basis.my upload speed is only 15KB/s and uploading a 15mb PDF file takes 20 minutes.i will test this software and if it works will use it to compress my PDFs' before uploading to save time.

I don't want to pile on but, how is a reduction from 30mb to 8mb a reduction of 23%? A reduction OF 8mb is approximately 23%. That comment gave me no confidence in this software.

... To reduce the size of PDF file ...
Some time ago someone mentioned this Orpalis PDF Reducer.
I tried it out and now its my favorite for shrinking PDF files.
Good results with a little efford (getting rid of the nagscreens after 3 -5 PDF files each batch processing).

Thanks for the information just couldn't believe anyone would produce such a useless program.

This can be achieved in PDFill PDF Tools (Free) with a better choice of options.
http://www.pdfill.com/pdf_tools_free.html

Using it just convert to image, compress it further and then convert back to PDF with the advantage of a good selection of DPI in the first conversion.

i didnt install that sw - i dont need it. but from my experience: if you have a pdf combining normal (editable) text and images, such programs sometimes convert text into raster image too. and that causes MUCH greater, not smaller file (and jaggy no-editable text). for really only-image pdf (e.g.scanned pages) it can work, but the same result you can probably get with printing your pdf with a "pdf-printer" to another pdf with lower dpi settings. ofcourse you loss quality, but this program dosent preserve it too...

@ 3. XP-man

This program works ok exclusively for scans, without any normal text string converted in PDF file.

Installed and registered with no difficulty, opened to a program devoid of options other than compression level.

Really looking forward to using today's download; a recent giveaway was a file search program and a program of this type that I wrote fulfilled a lot of requests contained in the comments and I wanted to put it out as freeware.
My help files are always written in PDF format for the simple reason it is easy to make clean looking documents that contain lots of information.
Images that look very small on the page in this format can be zoomed without any loss of quality unlike most wordprocessor documents.

My file was created in OpenOffice and consisted of a number of high-quality images and text giving a total size of 140 K.
I tried compressing it to a reasonably high quality level using this program and it became 370 K with poor quality in the images.
To actually get it smaller than the original I had to go to 2% (137 K) on the slider in the program, the resulting document has absolutely no detail in the images.
Putting the slider to 97% produced a document of 739 K, this showed considerable deterioration in the image quality compared to the original.

Very disappointed as the program did more harm than good and will be removed from my computer ASAP.

Reducing the image quality is an irreversible process, so better keep a copy of the original PDF and only use the "compressed" version for sending across the Internet if bandwidth is limited.

On another note, while to the human eye the compressed image-quality might look acceptable on the screen, a better quality is required when printing because the printer page has many more pixels than most monitors.

Installed and registered without problems on a WIn 8.1.2 Pro 64 bit system.

This is a so called PDF compressor, it is in reality a simple picture size "reducer". It works only with PDF, which are a collection of scanned pictures, reducing the DPI from let's say 300 to DPI 120. With the corresponding loss of quality, but an of course reduced file size.

Keep in mind, what they write about this software :

2. Why the compressed PDF file is still big or larger?

First please check if your PDF files are scanned PDF or not. Scanned PDF documents are made from images so that the program can compress it. If the PDF files are not scanned PDF, the compressor will not work properly and make files bigger than before.

Another reason may be the PDF file has been compressed already. Once the PDF file has been compressed, you cannot compress it twice.

3. Why the compressed PDF Pages are Blurring?

Please check the Compress Quality and DPI value. If these two values are too low, the compressed PDF file could not keep the good quality. Try to turn the Compress Quality higher than 75% and set the DPI to 120.

http://www.pdfcompressor.net/tutorial.html#2

A simple, non resizable window opens, you select your PDF(s), enter a target DPI (120 is the default, 100 the minimum and 500 nonsense), a compress "quality", which correspond to the JPG quality, in the save dialogs of your picture tools.

A link answers the question : Why the Compressed PDF is still big?

After compression is does not open the output folder or the PDF file.

I have made a short test - a German catalogue with mostly images compressed from 49 MB to 28 MB, given the default DPI 120 and the preferred quality 75%.

This is the original PDF:
http://www1.xup.to/exec/ximg.php?fid=14674183
This the reduced size:
http://www1.xup.to/exec/ximg.php?fid=98596120

In this case you don't see a real quality loss. It depends from the original picture quality.

Does what it claims. If you have ACROBAT, you don't need it (of course!)

A simple PDF tool, keep it, if you want to reduce the size and the image quality of your PDF.

I don't need it. Uninstalled via reboot.
