That's a really interesting approach, SamTinnerholm! Giving away risk-free arbitrage opportunities is a unique way to attract and engage users. I'm curious, how do you ensure the security and privacy of the data involved in these transactions? Also, have you considered any specific measures to prevent abuse or misuse of these opportunities? It would be great to hear more about the technical challenges you faced and how you overcame them.

Hi HN, OP here!

I built this over the weekend because I was frustrated with existing HEIC converters. Most of them require uploading files to a remote server, and as an iPhone user on Windows, I didn't feel comfortable sending my personal photos to unknown servers just to convert them.

So I hacked together this client-side solution.

The Tech Stack:

Framework: Next.js (App Router) + Tailwind CSS

Core: WebAssembly (WASM) for local processing

Hosting: Vercel

Why it matters:

Privacy: 0 bytes uploaded. Everything happens in your browser memory.

Speed: No upload/download latency.

Cost: Free (hosted on Vercel's free tier).

It's still an MVP. I'd love to hear your feedback on the conversion speed or if you run into any edge cases with large batches!
