I built Convertaverse because I was tired of "free" file converters that were either buried in ads or required a $20/month subscription just to convert a single large file. How it works: Credits, Not Subscriptions: It uses a pay-as-you-go model. If you use it once a month, you shouldn't be on a recurring bill. Credits never expire. API Access: I’ve exposed the engine via an API for anyone who wants to automate file workflows in their own projects without enterprise-level costs. Tech Stack: Frontend is Next.js on Vercel; the heavy lifting is handled by Go/Python services on Railway.…

Hi HN, I’ve been experimenting with how much file conversion can realistically be pushed into the browser. Last year I tried compiling LibreOffice headless to WASM. The smallest build I could get was ~150MB — far too large just to convert a DOCX to PDF. That’s when I shifted to a hybrid approach. Today ~90% of conversions run client-side using WASM (FFmpeg, PDF/image tooling, spreadsheets, etc.). The heavier edge cases fall back to a small server pipeline (LibreOffice, Pandoc, Poppler).

Hello HN, I've used a lot of image converter websites to run for my daily jobs, but they required uploading my assets on their servers which I didn't like.
