Much larger file on Safari(Mac) or iOS compared to Chrome(Mac) #459

Current Behavior

I'm currently having an issue when generating an image with html-to-image on iOS as it takes quite a long time compared to Android. I was able to reproduce it using Safari on Mac versus using Chrome I've noticed that regardless of the quality settings or formats or any other property that I pass on the options object, the image file size generated initially on Safari is much larger than in Chrome. On a small image, on Safari the file size can be around 8/9 MBs while on Chrome it can be around 200/300 KBs This is also impacting the time to get the final screenshot as the request is much larger.

Did anyone run into the same issue?

Steps To Reproduce

  1. Use html-to-image on Safari
  2. Check Network tab to see the requests when the screenshot is taken
  3. Compare with Chrome
