What it does
ConvertCraft is a browser-first file lab with 120+ tools for images, video, PDFs, and more. Unlike bloated online converters, it runs tools locally for speed and privacy. We grew to 95,000+ monthly requests with zero marketing, proving users want a clean, fast alternative. The Pro plan removes limits and keeps files on your device.
124+ conversion tools powered by the ConvertCraft WASM Cloud. Most run locally in your browser. Advanced features use our private cloud helpers that auto-delete files after processing. Sub-2s conversions.
Tools that can run locally are processed locally. Server-assisted tools use temporary processing and automatic cleanup when needed. Many tools run entirely in your browser using WebAssembly — your files never leave your device for those tools. Hybrid architecture: local-first where possible, private helpers with auto-delete when extra power is needed. No tracking. Sub-2 second conversions powered by the Nuclear Engine. No waiting for uploads or downloads. I built ConvertCraft in a focused 45-day sprint as a solo developer, with AI helping me move faster and stay consistent. The hardest part was not writing code — it was staying steady through long nights, fixing edge-cases, and rebuilding…from convert-craft.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
