FileDiff.net is a fast, free, online file comparison tool. You can compare text, PDF files, binary files, website content (by providing the URL to automatically retrieve), and view the resulting comparison in a visually intuitive format. The resulting diff supports advanced features that are generally not available from other online tools, such as the ability to collapse and expand groups of lines that are identical between files, scrolling in one file automatically scrolls the other file (to keep the applicable line comparisons aligned), having a permanent link of the diff to share with colleagues, being able to embed the diff result in your own website or in a forum / help site, and being able to compare large files.
