HTML5 File Reader API - image quality

Question

hey i have this simple piece of code to read image from input file in a form:

 var reader = new FileReader();
        reader.onload = fileOnload;
        reader.readAsDataURL(file);

then i send the file binary via ajax, but when it comes an image and i save it the image quality is little bit lost, is there any way to specify in html5 quality of the image while reading that ?

Or it's only a server side problem?

Answer 1

The File Reader API doesn't modify the files. If the quality is being changed it is because you are modifying the file on the server (instead of saving it directly).
