ASPX stands for Active Server Page Extended. It’s designed for Microsoft’s ASP.NET framework. The code or element in the APSX file is processed on a web server. The code or scripts help to tell the browser how to open or show a certain webpage.  

Most of the case, you might have seen .aspx in a URL like this:

Or when your browser sends you an .aspx file to download. This usually indicates some communication problem with the website and the browser. 

If you accidentally download an .aspx file, no need to worry about that. Here we will show you how to open and edit it fast and easily! 

How to open ASPX files? 

In most case, if you download a file with the extension .aspx, it is very likely that something is wrong with the website or your browser. To open an .aspx file: 

1) Rename the file. The easiest thing to do is to change the file extension to the file type you want. For example, you can change the file extension to .pdf and then open the file. If you want it to be an image, just change it to .jpg. Fast and easy.  

2) Re-download the file from another browser. As mentioned, if your browser failed to talk to a certain web page about how to display it well, then you are very likely to have an .aspx file downloaded.

To fix it, just change to another browser and download again. For instance, you can change from Google Chrome to Firefox and re-download from the same web page.

If the file is still with aspx extension, you may want to contact the website administrator and tell them about some issues with their web page.
