I am trying to export the konvaJs stage as base64 using stage.toDataURL().
I would like to export the stage with size 36 by 48 inch which is 10800 by 14400 resolution.
I am using pixelRatio to generate the exported output with this desired resolution.
It is a huge resolution. I have all the konvaJS logic on client side. Exporting such a huge resolution is impacting the performance as the final output is above 50MB.

I tried setting quality to 0.5 but still the size of final output is huge.
Is there any better solution that I could use.
I appreciate any help with this please.
