    iOS Mobile File Upload for Form. Image Compression.

    Asked by oscarmorrison on March 22, 2013 at 03:07 AM

    Hi Jotforms. I am making, using your forms a House Expense form.

    Eg. enter items, select payer, then the persons selects upload file and takes a picture of a reciept.

    This is then emailed to all recipients and compiled in a spreadsheet for sum tallying.

     

    This is currently working near perfect, EXCEPT. When iphone take picture, the file is 2mb +.

    I want to make it so that the image is a maximum resolution of 500px wide.

     

    Can you please help!

    I think you will need to use a specialized app for this. There are great free apps that can crop/resize the image to make it smaller.

    Hi oscarmorrison, Jotform support,

     

    Very interesting matter, I am looking into the same thing for my own iPad form. I guess you are talking about client-side image compression (or even resizing would make the file a lot smaller) before upload...is that right?

    Did you find a solution for this yet?

    I know that there are a couple of fully JS solutions and some which use libraries, I think all of them using the HTML5 canvas. I was not yet able to integrate this into the Jotform file upload component, but maybe Jotform support can help us out a little on this?

     

    These are the ones I found:

    @JotformSupport, is there a(n easy) way to integrate one of these compression/resizing methods into the Jotform File upload component?

     

    Thanks a lot!
