Stop uploading your photos to random servers: A 100% Client-Side HEIC to PNG Converter
Hi Dev.to community! 👋
We’ve all been there: you Airdrop a batch of photos from your iPhone to your workstation, only to realize they are in .heic format, and your design tool or web project won't accept them.
The typical solution is to google "HEIC to PNG" and click the first link. But as developers, we know the trade-offs of most "free" online converters:
- Privacy Risks: You’re uploading personal images to a remote server.
- Speed Bottlenecks: You have to wait for the upload, server processing, and the download.
- Data Limits: Many sites cap how many files you can convert for free.
I decided to build a better, "dev-native" way to handle this.
🚀 Introducing heictopng.org
I built this tool with a Privacy-First architecture. Unlike traditional converters, heictopng.org does 100% of the heavy lifting inside your browser.
🛠The Tech Stack & Why It Matters
- Next.js & Tailwind CSS: For a snappy, responsive UI.
- Client-side Processing: By using modern browser capabilities, the conversion happens locally on your machine.
- Zero Server Uploads: Your images never leave your computer. This makes it incredibly fast (no upload lag) and inherently secure.
✨ Key Features
- Bulk Conversion: Drag and drop an entire folder of HEIC files and watch them convert in parallel.
- Lightning Fast: Because there’s no network latency for the file data, it’s often faster than professional desktop software.
- No Sign-ups / No Bloat: Just a clean, functional tool for a specific task.
💡 Why I’m Sharing This
As an independent developer, I’m passionate about building "Single Purpose Tools" that do one thing perfectly without the bloat. I’d love for you to give it a try next time you’re wrestling with Apple’s image formats.

I’d love to hear your feedback! If you’re interested in the performance or how I handled the browser-side memory management for large images, let me know in the comments!
