RoundCorner allows you to effortlessly transform the right-angle corners of your photos into smoothly rounded corners. The application offers two convenient methods for achieving this effect: first, by manually entering the desired radius if you have a specific measurement in mind; alternatively, by using an interactive slider to dynamically adjust the corner radius until you achieve the desired appearance. Once you've customized your photo, you can easily save it back to your Photos app, store it locally on your iPhone/iPad, or save it to your iCloud drive. Additionally, RoundCorner facilitates seamless sharing of the rounded corner photo through various apps such as AirDrop, Messages, Mail, Books, and more. Interactive Change ================== By manipulating the slider within the range of 0 to the maximum possible corner radius determined by the selected photo, you can dynamically and interactively fine-tune the corner radius, seamlessly adjusting it back and forth until you achieve the desired level of satisfaction. Precise Corner Radius ===================== If you have a precise value in mind, you can input the corner radius directly using the number keypad. As you enter the desired number, the photo's corners will dynamically adjust. Simply tap "Done" upon completion or tap the photo to hide the number keypad. Please note that the maximum allowable value is limited to four digits. Save & Share ============ Save the rounded corner photo back to your Photos library. Share the photo with other Apps Help about this App Links to other useful Apps Note ==== The saved or shared rounded corner photo is in PNG format rather than JPG. This choice is made because JPG does not support transparency, specifically the alpha channel.
