Añade esquinas redondeadas a múltiples imágenes a la vez para diseños modernos y pulidos.
The Bulk Rounded Corners Tool is a powerful browser-based utility for adding rounded corners to multiple images at once. Perfect for creating modern, polished designs for websites, apps, and social media. Customize the corner radius and control individual corners for complete creative flexibility.
All processing happens locally in your browser using HTML5 Canvas, ensuring your images remain private and secure. No uploads, no server processing—just fast, efficient batch rounding with transparent backgrounds perfect for layered designs.
Rounded corners are created by clipping the image using a rounded rectangle path on an HTML5 canvas. The corner radius determines how curved each corner becomes. A larger radius creates more pronounced curves, while a smaller radius creates subtle rounding. The tool uses the arcTo() method to create smooth, mathematically perfect curves at each corner.
Yes! You have full control over individual corners. Enable or disable Top Left, Top Right, Bottom Left, and Bottom Right corners independently. This is useful for creating asymmetric designs, matching specific UI patterns (like rounded tabs), or achieving unique visual effects. Use the 'Toggle All' button to quickly enable or disable all corners at once.
The areas outside the rounded corners become transparent, creating a PNG with transparency. This allows the rounded images to blend seamlessly with any background when used in designs, websites, or applications. The transparent background is essential for modern, layered design work.
Common values: 10-20px for subtle rounding, 50-100px for moderate curves (good for profile pictures and cards), 200-300px for heavily rounded edges, and 500px for pill-shaped or circular effects on square images. The optimal radius depends on your image size and desired aesthetic. Experiment with the slider to find what looks best for your project.
Rounded corners are essential for modern web design: profile pictures and avatars, product images for e-commerce, social media graphics, app UI elements, website cards and thumbnails, banner images, icon creation, portfolio showcases, and branding materials. Rounded corners create a softer, more approachable aesthetic compared to sharp rectangular edges.
No, the rounding process does not degrade image quality. The original pixels within the rounded area are preserved exactly as they were. Only the corners are clipped, not re-sampled or compressed. The output is saved as PNG to maintain maximum quality and support the transparent background created by the rounding effect.
Yes! For square images, set the corner radius to at least half the image dimensions (e.g., 250px for a 500×500px image) to create a perfect circle. For best results, crop your images to square dimensions first, then apply a large corner radius. This is perfect for avatars, profile pictures, and circular icons.
You can process multiple images in a single batch. The tool handles each image sequentially to prevent memory issues. Processing time depends on image size and the number of files, but modern browsers efficiently handle dozens of images. All processed images can be downloaded individually or as a convenient ZIP archive.
Absolutely! The corner radius is applied based on the actual pixel dimensions, so it works with any aspect ratio: portrait, landscape, square, or custom sizes. The same radius value will create proportionally consistent curves regardless of image dimensions. However, very small radius values may be less visible on very large images.
Yes! After processing, the preview grid displays each image with the applied rounded corners. You can see exactly how each image looks with the current settings before downloading. If you want to adjust the corner radius or toggle specific corners, simply change the settings and process the images again.
