PDF Editor Online - Formating Issues

We are considering using PDF .NET for our apps but while checking Online Demo page https://products.aspose.app/pdf/editor the formatting looks completely different with the actual file.

Texts are blurred. Texboxes have white background etc…
We tried on Edge and Chrome and having same issues.

We are wondering if this is just issue with the online demo page. Can we use .NET library to make a PDF Editor online page which show PDF content similar to the viewer on desktop?

As far as back-end API (Aspose.PDF for .NET) is concerned, we’ll test the provided files and share outcomes with you ASAP.


Please have a look at these images.zip (2.2 MB) generated using Aspose.PDF for .NET version 22.2. In case you have any back-end API related queries, please post on forum.aspose.com.


Are these files exported using Aspose .PDF for .NET?

We are looking for a solution to solve this business case below:

  • User able to upload a PDF form
  • Fill in the PDF form directly in browser
  • When user click Save button on webpage, backend system will be able to save as PDF form with filled in data and store the file

So we would like to show PDF form in browser as it is in Acrobat Reader.


Yes. Please note that Aspose.PDF for .NET is a back-end API that can be integrated in any .NET project.
Looking at your use-case, you have to develop your own UI:

  • To upload the file
  • To fill and save it

You can also explore the Source code for the live web app. In case of any back-end API related query, please post on forum.aspose.com.
