I've spent the last month building OptiDrop — a free toolkit with 300+ tools (image compression, PDF tools, calculators, resume builder, developer utilities like JSON/JWT/Base64) that run entirely in the browser. No file ever gets uploaded to a server — everything processes client-side.
Why I built it this way
I kept running into the same problem: needing a quick tool for something (compress an image, merge a PDF) and not wanting to upload personal or sensitive files to some random server to do it. So I built a version where the processing happens entirely on your device.
How I built it
Solo project — I'm a student, no funding, no team. Some of it I wrote by hand, some with Claude Code, mostly HTML/CSS/vanilla JS, deployed on Vercel.
Where I'm stuck
Technically it works well, but I have almost no idea how to get real people to find it. My traffic right now is basically me, a few friends, and search bots. I'd genuinely appreciate feedback on:
- What would make you trust a "no upload" claim from a tool you've never heard of?
- If you've built something similar, what actually got you your first real users?

Open to any feedback — brutal is fine.`
