Compare PDF files – Install DiffPDF on Ubuntu and derivatives
The program is especially useful when you have two very similar files and want to discover the small differences between them.
By default, text comparison is done on each pair of pages, but comparing the visual aspect of the pages is also supported (for example, if a diagram is changed or if it is a reformatted point). It is also possible to compare certain pages or ranges of pages.
The program shows pairs of pages from the two PDFs that are being compared with any highlighted differences.
Comparisons can be made based on text, regardless of layout, or based on appearance (which accounts for fonts, colors, layout, diagrams, images, etc.).
DiffPDF is useful for those who need to compare PDF files, reports, book and labels, such as archivists, engineers, journalists, packagers, editors, researchers, software testers and translators.
Because of this, the program is used in a wide variety of contexts, from book authors from banks, insurance companies and government.
