I built a privacy-focused tool to crop images into circles instantly

Hey Dev.to community! ๐Ÿ‘‹

I often faced a small but annoying problem: I needed a circular version of an image file (actual PNG with transparency), not just a visual circle created by CSS border-radius.

Opening Photoshop just to crop a profile picture felt like overkill. So, I built a lightweight tool to solve this.
Meet Circle Crop Image.

๐Ÿš€ What it does

Itโ€™s a simple web utility that lets you upload an image, select a circular area, and download it as a transparent PNG.

๐Ÿ’ก Key Features

  • Client-Side Processing: Your images are processed locally in your browser using the Canvas API. Nothing is uploaded to a server. 100% Privacy.
  • Instant Export: No sign-ups, no watermarks, no ads.
  • Responsive: Works great on mobile if you need to create stickers or avatars on the go.

๐Ÿ›  Under the hood

It relies heavily on the HTML5 Canvas API (ctx.arc, ctx.clip). I wanted to keep it dependency-free and fast.

I'd love for you to try it out and let me know what you think. Is there any feature you'd like to see added?

Thanks for checking it out!
