Why round an image's corners?
Rounded corners are everywhere in modern design — app icons, cards, avatars, thumbnails, UI mockups. Softening the sharp 90° corners of a photo makes it feel friendlier and more polished, and it helps an image sit comfortably inside rounded buttons, cards, and containers.
This tool rounds all four corners by the radius you choose, set as a percentage so it scales with the image. With a PNG or WebP output, the area outside the rounded corners is kept fully transparent, so the image drops onto any background cleanly. Choose a solid background colour instead if you'd rather fill the corners.
How to round the corners of an image
- Open your image. Drag it onto the tool, choose a file, or paste it.
- Set the radius. Drag the rounded-corners slider until the curve looks right. Keep the border at zero for corners only, or add a border too.
- Keep it transparent and download. Leave the background transparent (PNG/WebP) so the corners cut out cleanly, then click Download.
Keep a transparent output
For rounded corners to actually cut out, export as PNG or WebP with the background set to Transparent. If you export as JPG — which can't store transparency — the corners are filled with your chosen background colour instead.
Esquinas redondeadas : qué es y sus controles
Las cuatro esquinas afiladas de 90° de la foto sustituidas por una curva suave, sin necesidad de banda de color.
- Radio
- Un porcentaje del lado más corto (0–50%), limitado a la mitad para que no se redondee de más; en el máximo, una imagen cuadrada se convierte en círculo/píldora.
- Borde (opcional)
- Mantén el ancho en 0 para solo esquinas; añade también un borde y tanto el marco exterior como la foto se redondean juntos, manteniendo la curva interior concéntrica.
- Transparencia
- Exporta PNG o WebP con el fondo en Transparente para que la zona fuera de la curva se recorte de verdad; JPG no puede guardar alfa y la rellena con un color.
Cuándo usarlo
- Iconos de app, avatares y miniaturas de tarjeta
- Imágenes que van dentro de botones o contenedores de UI redondeados
- Una sensación más suave y amable que las esquinas duras
- Maquetas y recursos de diseño que necesitan una forma recortada
Consejo
Las esquinas redondeadas solo se ven redondeadas sobre un lienzo transparente: exporta PNG o WebP con Transparente activado, o las esquinas se rellenarán con el color de fondo sobre el que exportaste.

Preguntas frecuentes
How do I round just the corners, without a border?
Set the border width to zero and drag the rounded-corners slider. Only the corners are rounded; no frame is added.
Will the corners be transparent?
Yes, if you export as PNG or WebP with the background set to Transparent. JPG can't store transparency, so it fills the corners with a colour instead.
Can I round corners and add a border at the same time?
Yes. Add a border and a radius together — the outer frame and the photo are both rounded, with the curves kept concentric.
Where is my image processed?
The border is added in your browser, so the new file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
