I created a tool to generate OGP and PWA images

2025-07-05

There's an app called Image2icon.

When building a website and adding PWA support, you need to prepare icons for both Android and iOS.

Creating these PWA-compatible icons can be a bit of a hassle, so I used to rely on that app.

However, PNG export is only available in the paid version, and it offers a lot of trimming features I didn’t really need. It felt a bit too much for my use case.


So I decided to build a minimal image generator with just the essential outputs and basic trimming options.

Here it is: 👉 OGP Image Generator

The tool currently outputs the following image types:

  • favicon.ico (256px)
  • apple-icon.png (180px)
  • icon-192x192.png (192px)
  • icon-512x512.png (512px)

I believe this set covers the minimum required icons for most PWA setups... though it’s surprisingly hard to find consistent documentation on this.

Feel free to give it a try—I’d love to hear what you think!
