There are multiple reasons for the 1 MB per file upload limit.

Here's a short explanation what is done with your images:
I'm not storing the name of your files, metadata (like geo location) or anything else that belongs to your privacy. The metadata is only read to be displayed in the results and is not stored.
The only information stored (for statistical reasons) is not privacy-related and helps improving the tool:
In most cases you've uploaded images that are too large and the encoded string
exceeds the limit of 32 KB, which is set by Microsoft. Internet Explorer 9 has a greater limit of 4 GB.
If you need to support IE 8 users you really have to look at the size of the base64 strings.
There's only a very small percentage (~ 0.5%) of users with these outdated browsers,
using this tool. The easiest way to get Drag & Drop up and running was
to use Dropzone.js, which doesn't support IE < 10.
For older browsers there's a single file upload form you can still use.
