Compare PDF in cURL

Our cURL SDK is designed to give you the most accurate result, even though comparison is a complex function itself.

Sometimes you need to be sure that the document in the PDF format has not been changed, and if it has, you need to find out what the difference is. Just use our cURL diff tool to compare two PDF files and find differences in whole words or single characters. Moreover, if only one character in a word has changed, this word will be marked as changed entirely.

Now you no longer need to spend time manually comparing PDF documents, and you can quickly find even small changes and export such diffs to a document in a convenient format.
