Is it possible to modify a .FLA file to the HTML5 format? If, yes then how to do this?

Dear Sir or Madam,

Flash will not be supported by Chrome and Edge (Chromium) at the end of next December.

In 2006, I developped this website with Flash 8: Image Style Studio and this website is always online over the Web. It contains Video made with the Flash technology... 😉

Is it possible to get it back in HTML5, because I have always the access to the .FLA file?

Perhaps it is possible with Edge Animate or Animate CC, I do not know?

I look forward to reading you.

Yours faithfully,

John
