I like how it changes the dimension. But converting to PNG is massively increasing the file size?

"Original file was: 137724 bytes Transmitted size was: 844176 bytes (due to base64) New file is: 633131 bytes"

It might be - not sure it's just a PNG issue, or if it's a canvas flaw, or what. The system could ideally check the before/after sizes, and only send the smaller one. Good catch (I think I'd seen that once in testing too).
