Replace Text in all pages of a PDF Document

Now I have trial version of aspose.

I want to change format of specified text in all pages of a PDF.

It’s run successfully by using of following code.
Replace Text in PDF|Aspose.PDF for .NET

But after checking new saved file, all text format are not changed.
and also if I search “Information” text and in actual PDF, Information work like “Information”, “INFORMATION”, “information”. ALL word should be count in search and also format.

If I will purchased then all text format will be changed?

Hi there,


Thanks for
your considering Aspose. Yes, purchasing Aspose.PDF will resolve the issue. As Aspose.Pdf evaluation version has
two limitations, evaluation watermark and at most four elements of any
collection can be viewed/changed. However you may request for a 30 days temporary license to evaluate our product without
any limitation to verify your requirements, before the purchase of product. It will help you to change format of all the desired text in whole PDF document.


Moreover, in reference to different cases of searched text, you may use regular expression for case insensitive search. Please check documentation link for the purpose.Hopefully it will help you to accomplish the task.

Please feel free to contact us for any further assistance.
