Optimize PDF eBook File For iPhone & Android Mobile Devices

PDF is now a standard with almost every mobile and eBook reader supporting it. The importance of PDF documents cannot be underestimated. It has to be kept in mind that PDF files can go as high as hundreds of megabytes when filled with graphics and other visually appealing styles.

PDF documents were originally meant to be read on the desktop, and optimized for this very purpose. Most users now want to experience it on the devices with small screens. The breakneck growth of mobile devices and eBook readers have increased the demand of PDF support on these devices. As an example both iOS and Android natively support PDF format.

Suppose you have Nexus One, HTC Desire, EVO 4G, Droid Incredible, or even an iPhone, the question is, will you load a 200MB PDF document in the device or will you resize, crop, and optimize it, so that it can load faster and take less space?

PaperCrop is an opensource tool that will crop, resize, and optimize the PDF file in such a way that the experience wouldn’t change but the file will take less space than the original document.

According to most users, the best method to load a PDF file into a mobile device is to convert it’s pages into images. Even though, this software is also capable of converting pages into images, this is definitely not the best way.

What PaperCrop does best is to optimize the PDF pages and reduce the size, all while keeping the same original PDF format. In the end you will have a resized and optimized PDF file which will take less space and is equally impressive on a small screen.

Another advantage of keeping the PDF format is that it can easily organized in iBooks app which can be found in both iPad and iPhone. Since iBooks will be supporting the native PDF format, it makes sense to organize the books and documents in the original PDF format rather than converting it’s pages into images.


From the main interface, users can only crop and change the segmentation parameters. To resize the whole PDF document, open config.lua (which can be found in the same folder where the app is residing) with Notepad. Now change the device_width and device_height parameters as needed and save it. Please note that you will have to restart the application once the resolution is changed.

The usage can’t be more easier, you just have to load the PDF file (either by drag-and-drop or by clicking the Load button), hit Default Present button, choose the style and hit OK. When all is done, finally click Process All Pages.

If you are a more advanced user, you might want to play around with segmentation parameters. And if you want to set the segmentation manually, uncheck “Use automatic segmentation” and select the region by clicking and dragging.

Once getting used to it, the application becomes fairly easy to use. The best part is that it is a portable application which means optimizing PDF files while on the go is finally possible.

The application works on Windows XP, Windows Vista, and Windows 7. We tested the application on Windows 7 32-bit OS and it worked like a charm.
