Text comparison software is very useful for us, for example, after the upgrade of php code, some places will be improved, if you want to know which places have made changes, then the use of two eyes is not able to do this thing. And what about a pdf document, which is difficult to edit? That will make people even more crazy, fortunately there is DiffPDF this software, to allow you to compare the differences in pdf documents.
Although pdf documents are not used at all in normal times. However, they are often encountered in the office. The non-editable nature of the document also makes it ideal for use as an electronic version of a document such as a contract. If you encounter the need to compare two pdf documents at work, then you can only blame the following two points for encountering such a tragic job.
1, born with a bad fate, or called RP can not.
2, DiffPDF this software is completely free, you can take it with you to use.
Does it have other uses?
In fact, this is still a single-file green version of the pdf reader. So after using this software adobe reader can be laid off. Because in terms of size, the latter is too large.
As a result of not being able to open a single document, so if you want to use DiffPDF as a reader, you need to open two files at a time, if you need to browse more pdf, then this is also considered a pdf reader with tabs.
If you only want to view one of the articles, use the mouse to drag the middle to hide the other file.
To use as a comparison tool.
Click on the file to add a file, then click on “compare” on the right to compare. The differences are commented in red. If you don’t like the colour, you can change it to something else.
