Can I adjust the thickness of the borders?
Yes, you can use our interactive slider to set border thickness from a hairline 1px stroke up to a massive 200px framing block. The layout updates instantly in the canvas preview.
Will adding a border reduce my photo quality?
Absolutely not. Our tool uses HTML5 Canvas to perform the layout calculations at high resolution. When you download the finished image, it exports at its native size with no compression degradation.
How does independent corner rounding work?
Our advanced editor gives you separate sliders for the **inner corner radius** (the image itself) and the **outer corner radius** (the framing border). This allows you to create nested concentric curves that fit together perfectly without distortion.
Can I add transparent margins around my image?
Yes! By choosing a transparent border option or dropping the alpha channel slider of the background color to zero, you can add transparent margins to any PNG or WebP image, perfect for creating logo spacing offsets.
