What is an Image Resizer & Round Corners Tool?
This tool lets you upload an image, resize it online, round its corners, and download the final output.
It is useful for preparing avatars, card thumbnails, and hero graphics without opening heavy desktop software.
How to use
- Upload an image file from your device.
- Set output width and height, and optionally keep aspect ratio locked.
- Adjust corner radius to create rounded edges.
- Pick output format and quality.

Example usage
Resize a product thumbnail to fixed dimensions and apply a 16px radius so it matches your card component style.
Tips
- Use WEBP for smaller file size when browser support is acceptable.
- Keep radius proportional to image size for balanced visuals.
- Avoid extreme upscaling to preserve sharpness.
- Use consistent output dimensions for UI grids.
