6. 個人經驗與觀點
「GIF 仲未死，唔係因為佢好，而係因為 人懶得轉。你知唔知一條 10MB 嘅 GIF 轉成 WebM 之後可以細到 2MB，畫質仲要靚幾倍？GIF 嘅存在係一種集體慣性——你以為佢方便，但其實你每 Share 一次，就浪費緊人哋嘅 bandwidth。呢個工具嘅價值唔係俾你『玩轉檔』，而係俾你 做一個負責任嘅網絡公民。GIF 係時候退休，WebM 係未來。」

6. Personal Insights & Expert Advice
"GIF is still alive not because it's good—but because people are too lazy to switch. Did you know a 10MB GIF can become a 2MB WebM with better quality? GIF's existence is collective inertia—you think it's convenient, but every time you share one, you're wasting someone's bandwidth. This tool isn't about 'playing with conversion'—it's about being a responsible netizen. GIF should retire. WebM is the future."
