What is the fastest way to equalize the right and left spaces of a huge PDF file (other than 'removing white spaces')?
In Acrobat Pro you can use the following technique. Use the Crop tool to remove any margins around your area so the actual content of pages touches borders on all sides. Make sure to apply that to all pages. In the Find field search for scale page. Use one of the Scale pages to italic fixups to scale to one of the standard page sizes or Scale pages to specified size italic if you need to scale to a custom size. Margin time search for another fixup Scale page content only to specified size italic . It will ask for the scaling factor play with values between 9 and 97%. This will result in symmetrical margins. As a bonus hack you can play with headers and footers. Acrobat allows to add them with a tool in the Edit PDF group. So you may want to crop out the original ones keeping only the actual content of the page and after performing the steps above you can add a new header or footer to your liking. After initial cropping you may also want to remove the cropped-out original headers with another fixup Remove page objects which arepletely outside of page area italic so they don increase file size and keep things tidy.
Why are portable document format (PDF) files so commonly used?
Because there is a business niche that PDF was created to fill 3 years ago that still exists and PDF is now so mature that it is unrivaled bypetitor formats. That niche is serving as a digital printout and a number of bordering uses. PDF main objective is precisely capturing the appearance of any document or output of any application; identically across platforms and immutably if need be. This original application spawned popularity and further feature development for professional printing archival paperless and secure business document workflows forms engineering and multimedia accessibility and many others. PDF was also the first such format adapted for Internet delivery (as was its apanying free viewer software Acrobat Reader). At the end of th 9s Adobe the creator of both worked with Netscape the then browser market challenger and innovator to develop the concept of plugins extending the browser's functionality to enable the seamless progressive display of PDF as it was being downloaded just like HTML pages. The Acrobat plugin was also downloadable for free. At the time there were no other ways to publish universallypatible and pixel-perfect replicas of carefully designed documents (or books and magazines) to the browser. That as well as PDF's adoption by the IRS in the US hugely contributed to the format's ubiquity and popularity.
