Why convert ASHX to JPG?
ASP.NET image handlers serve photo or image responses under a URL ending in .ashx, and browsers sometimes save the file using that URL as the filename. The underlying bytes are already a .jpg or PNG; only the extension label is wrong.

- A genuine
.ashxfile is server-side C# or VB.NET source code - no dedicated converter exists or is needed; only misnamed image downloads benefit from a rename. - If renaming to
.jpgfails, inspect the actual content: open the file in a text editor and check the first few characters (JFIFindicates JPEG,PNGindicates PNG,%PDFindicates PDF). - Sites claiming to convert
.ashxto JPG work only because the uploaded file was already a JPEG - no actual conversion occurs.
Frequently asked questions
Should I rename to .jpg or .png?
Try
.jpg first; if it does not open correctly, try .png - the server may have served either format.Can I right-click the image on the website instead of downloading and renaming?
Yes - right-clicking the image and choosing 'Save image as' lets you set the correct filename and extension before saving, bypassing the wrong name entirely.
What if the renamed file shows garbled content?
The downloaded content is not an image; open it in a text editor to check what the server actually sent - it may be a PDF, HTML, or an error message.
