Problem uploading images to server (Safari iOS6)?

Question

safari

As many already know, with the release of iOS6, Safari introduced support for uploading media content to the server. So, I ran into the following problem, which I can not solve in any way for a day.
There is a source image image.png (100% quality) which is stored on the server. There is a script that compares the loaded image with the original rgb values ​​of the pixel group. If the values ​​match, then the test passed. The whole thing works fine everywhere except in ios.
I save .png images to the “camera film” on the iPad, upload it via safari to the server, and the compressed .jpg arrives on the server and, accordingly, the script sees a completely different picture. And when you try to send from the film to the mail, the original png file comes. I don't know how to deal with this conversion and compression to .jpg. Maybe someone faced a similar problem and knows its solution. Thank you in advance.
