Round Image Corners and Add Borders
Soften the edges, crop to a circle and add colored frames with a transparent background. Several images at once, all in your browser.
How to round corners and add borders
Start by dragging your images onto the upload area, or click it to open your file picker. You can send several photos at once by holding Ctrl (or Cmd on a Mac) while selecting, and the accepted formats are JPG, PNG, WEBP, GIF and BMP. With more than one file loaded, tabs named after each image appear above the preview — click to switch between them and check how your settings look on each photo. Just under the preview, the final file dimensions are shown in pixels, already counting any border you add.
The first decision is the shape. Rounded corners keeps the original proportions of the photo and simply softens the edges. Circle center-crops the image to a 1:1 ratio and applies a round mask — the right choice for profile pictures and avatars, because it avoids the squashing you get when a portrait photo is forced into a circle. Square just center-crops to 1:1 without any rounding. In rounded-corners mode, the radius slider controls the curvature as a percentage of the shorter side, and the four buttons below let you switch off specific corners: click one and that corner goes back to being square.
Border thickness is set in pixels and drawn outside the image, so nothing of the original content gets cropped. As soon as the value goes above zero, a color picker, a hex code field and a palette of eight ready-made colors appear. The border follows whatever curvature you chose, so in circle mode it becomes a perfect ring. The soft shadow option adds a subtle lift behind the image, handy for thumbnails that sit on light backgrounds. The transparent background box is ticked by default, and it is what guarantees the cut corners are genuinely see-through.
Finally, pick a download format. PNG is the recommended default because it preserves the transparency of the corners with no quality loss. WEBP also keeps transparency and produces smaller files, which makes it ideal for use on a website. JPG has no transparency, so choosing it fills the corners with the background color set in the controls. Use the download image button to save just the photo on screen, or download all to receive the whole batch as a .zip archive with identical settings applied.
