How to use this tool

  1. Upload any photo or illustration (JPG, PNG, WebP, SVG) by dragging and dropping it into the workspace, clicking to browse, or pasting from clipboard (Ctrl+V / Cmd+V).

  2. Choose between Uniform Mode (adjust all corners simultaneously) or Individual Mode (customize Top-Left, Top-Right, Bottom-Right, Bottom-Left independently).

  3. Use the Corner Radius slider or pick a preset like 'iOS App Squircle', 'Subtle Card (16px)', 'Capsule Pill', or 'Asymmetric Leaf'.

  4. Toggle background mode between Transparent (for PNG cutout) or a solid background color fill (e.g. white, black, or custom hex).

  5. Optionally add a sleek decorative border stroke around the rounded boundary with customizable thickness and color.

  6. Optionally add a soft drop shadow with custom blur, offset, and shadow color for realistic floating card depth.

  7. Inspect the live interactive preview to evaluate corner rounding and anti-aliasing against a checkerboard transparency background.

  8. Export your rounded image at full original resolution in lossless PNG (for transparency) or high-quality JPEG.

Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

When exporting in PNG format with transparency enabled, all pixels outside the curved corner path are completely transparent (alpha = 0). If you export in JPEG or select a solid background color, the clipped corner area is filled with your chosen background color since JPEG does not support alpha transparency.
A standard rounded rectangle uses circular corner arcs, which can create a noticeable sudden change in curvature where straight edges meet curves. An iOS squircle (superellipse) employs progressive bezier easing that blends seamlessly from straight lines into smooth curves, creating a modern, organic silhouette.
Yes! Switch to Individual Mode to control Top-Left, Top-Right, Bottom-Right, and Bottom-Left corners independently. This makes it effortless to create browser tab cards, chat bubble cutouts, or asymmetric leaf designs.
No. The corner clipping path is calculated and rendered directly on an offscreen HTML5 canvas matching your image's 100% native pixel dimensions with subpixel anti-aliasing, preserving maximum sharpness and detail.
When Drop Shadow is enabled, the export canvas automatically expands by padding proportional to the shadow blur and offset so the shadow is never clipped at the edges, giving you a ready-to-use floating card asset.
No. 100% of the bezier path clipping, background filling, shadow rendering, and file encoding execute locally in your browser memory. Your images never leave your computer.
