Frequently Asked Questions
Rounding image corners softens the sharp edges of a picture by replacing square corners with curved ones. It is commonly used for profile images, website cards, app mockups, product graphics, social media visuals, and any design where a cleaner or more modern look fits better than a hard rectangular edge.
Yes. You can upload multiple images, choose the corner radius and export settings once, and apply that style across the full batch. You can preview any file from the queue, download one finished image at a time, or export the whole batch at once.
PNG is usually the safest and most widely compatible choice when you want transparent corners. WebP also supports transparency and can produce smaller files, but PNG is often preferred when you need predictable compatibility across design tools, websites, and apps.
JPG does not support transparency, so any area that would otherwise be transparent must be filled with a solid background color during export. If you need the corners to stay truly transparent, export the image as PNG or WebP instead of JPG.
The radius percentage is based on the smaller dimension of the image, which keeps the rounding proportional across different sizes. Higher values create more curved corners, and at 50 percent a square image becomes a circle. On a rectangular image, the same setting creates the most rounded possible corners without turning it into a perfect circle.
The corner effect itself does not reduce the visible detail inside the image. Final quality mainly depends on the export format you choose: PNG keeps crisp results and supports transparency, WebP can balance quality with smaller file size, and JPG uses compression that may slightly reduce image quality compared with PNG or lossless WebP.
