I used to think that flipping e-books getting blurry when zoomed in was just an industry-wide problem, and I always blamed "heavy compression" or "bad screens." Then a friend made a lecture handout on FLBOOK and sent it to me. I zoomed in until only four or five characters filled the whole page—and the text was still crisp. That's when I realized: the problem wasn't the tool, nor the resolution, but my PDF file. 1. First, an admission: I was blaming the wrong thing I fell into both traps: "it's blurry because the platform compresses it" and "free e-book versions must be limited in every way." Both wrong. Understanding one thing is enough—which type of PDF you upload determines the result
