OnepageDF 4‏+

'OnepageDF' is an interactive utility that converts a multiple-page PDF file into a single-page PDF file, with options to trim top and bottom margins for better on-screen viewing.

PDF is a convenient file format for creating, displaying, and sharing documents but its print-oriented structure that insists on representing documents as a collection of pages isn't necessarily the best approach to electronic presentation.

In its simplest form, 'OnepageDF' will open an existing PDF document and export a new one that is a single page, matching the total size of the original and with the content of the original. You can control the content that's exported by adjusting top, bottom, left, and right page margins to eliminate leading and trailing space. The program uses a translucent mask to indicate the excluded document sections.
