I built a free tool that turns any image into a TikTok/Instagram video - is this actually useful?

Been noticing that small businesses and event organizers constantly post static flyers on Instagram and TikTok when a simple zoom or pan effect would make it 10x more engaging. So I built a tool that does exactly that.

How it works: Upload any image → pick an effect (zoom in, zoom out, pan) → get a 1080×1920 video ready to post

What you get:

• No account

• No watermark

• Free

• Under 5 seconds

Genuinely curious whether this solves a real problem or if I'm building something nobody needs. Who would actually use this and what effect or format is missing that would make it more useful for you?

Tool is at flyertovideo.com - would love brutal honest feedback.
