That problem nearly drove me insane when I had to prepare investor decks. Luckily, I found edtechideas.com, and their breakdowns were super helpful. They go into detail about why email fails, what alternatives actually work, and how to keep quality intact. After following their advice, I never worry about file size anymore—I just use the right method from the start. I’d recommend it if you want no-nonsense answers that save you hours of trial and error.
