Rounded Corner Image Generator

Use the form below to upload an image and round off its corners to any radius you like, turning sharp square edges into a smooth curve. This is a common finishing touch for profile pictures, app icons, thumbnails and cards.

Drag a slider to set how rounded the corners are and watch the preview update instantly. The area outside the rounded shape becomes transparent, so the result drops cleanly onto any background without a visible square edge.

For your privacy and convenience, all processing is done directly in your browser, meaning that your images are never uploaded to our servers. This ensures your files remain secure while giving you instant results.

Getting a good result

App icons and avatars

A radius of roughly 10–20% of the image's width gives the soft, modern look used by most app icons and profile pictures.

Push it all the way for a pill or circle

Set the radius to half the shorter side (or drag it to the maximum) to turn a square image into a circle, or a rectangle into a capsule shape.

Keep the transparency

Save as PNG and place the result over a photo, colour or pattern — the cut corners will show whatever is behind them instead of a white or black square.

Frequently asked questions

Is my image uploaded anywhere?

No. The corners are rounded inside your browser, so your image never leaves your device and nothing is stored on our servers.

Why does the downloaded image have a transparent background?

The corners outside the rounded shape are removed rather than filled in with a colour, so the file is saved as a PNG with transparency. If you need a solid background behind the rounded image, add it in whatever program you open the file with, or place it over a coloured layer.

What happens if I set the radius higher than the image allows?

The radius is automatically capped at half of the image's shorter side, so dragging the slider all the way just gives you the roundest shape possible — a circle for a square image, or a pill shape for a rectangular one.

Which file types can I use, and what do I get back?

You can add PNG, JPG, GIF and WebP images. The result is always downloaded as a transparent PNG. For animated GIFs, only the first frame is used.

Why was my large image made smaller?

To keep your browser responsive, images longer than 4000 pixels on their longest side are scaled down before editing. The line under the preview shows the original and resized dimensions.
