Could you review this file conversion tool and give me some optimization suggestions?

Hi everyone! 👋
I’m a beginner web designer, and I just launched a site: https://fastconvert.ai/ — it’s a free online file conversion tool that lets users convert images, PDFs, videos and more quickly and easily in the browser.

I’d really appreciate it if you could take a look and give me some feedback! Here are a few things I’m curious about:
✅ Does the homepage clearly explain what the site does?
✅ Is the design layout easy to understand and use?
✅ Are there parts that feel confusing or could be improved?
✅ Any suggestions for better colors, spacing, or navigation?

Your honest feedback will help me learn and improve my web design skills 🙏

Thank you so much! 😊
