How much RAM can a website in iOS Safari use

Viewed 419

I am developing a browser-based photo editor Photopea. Many iOS users report, that it crashes on their iPads (latest iOS, 4 GB of RAM). Users work with large documents (big resolution, many layers) and Photopea may require 2 - 3 GB of RAM.

  • Is it known how much RAM websites are allowed to use in iOS Safari? Could you maybe test it on your iPad?
  • What is the best way to make Apple fix it?
