Image Rounded Corner Tool
Rounded corners are a small design detail that shows up everywhere from app icons to profile pictures to modern web cards. This tool lets you round the corners of any image by an adjustable radius, or go all the way to a full circular crop, exporting the result as a transparent PNG so it drops cleanly onto any background. Adjust the radius with a live preview, and download when it looks right.
How to Use Image Rounded Corner Tool
- Upload an image.
- Choose "Rounded corners" and set a radius, or choose "Full circle."
- Check the live preview against a transparency checkerboard.
- Download the result as a transparent PNG (or WebP).
Features & Benefits
- Adjustable corner radius from subtle rounding to a full "squircle" look.
- One-click full circle crop mode.
- Transparent PNG/WebP output so the shape works on any background.
- Live preview against a checkerboard so transparency is easy to verify.
Detailed Information
This tool uses the canvas 2D context's clipping-path feature: a rounded-rectangle (or full ellipse, for circle mode) path is defined and applied as a clip before the source image is drawn, so only pixels inside that shape are kept — everything outside becomes transparent. Because the output relies on transparency, the download format is restricted to formats that support an alpha channel (PNG and WebP); JPG cannot represent transparent pixels, so it's not offered here. The radius control is expressed in pixels and automatically capped at half the image's shortest side so it can't produce a broken shape.
Common Uses & Examples
- Creating a circular profile picture for a social media or app account.
- Rounding the corners of a product photo to match a card-based website design.
- Turning a square logo into an app-icon-style rounded square.
- Preparing an image cutout for a poster or collage layout.
Tips & Best Practices
- For app-icon-style results, a radius around 20% of the image width usually looks right.
- Circle mode works best on images where the subject is centered.
- Remember to export as PNG or WebP — JPG cannot preserve the transparent corners.
Privacy & Security
Clipping is performed locally in your browser using the Canvas API. Your image is never uploaded.
Conclusion
From a subtle rounded corner to a perfect circle crop, this tool produces a clean, transparent result ready to drop onto any design.
Frequently Asked Questions
No — JPG doesn't support transparency, so rounded/circular results are only offered as PNG or WebP.
Yes, choose "Full circle" mode instead of setting a corner radius.
No, the canvas clip path is anti-aliased, so edges look smooth.
Roughly 18–22% of the image's width is a common modern app-icon proportion.
