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.
Cantos arredondados : o que é e seus controles
Os quatro cantos retos de 90° da foto substituídos por uma curva suave — sem necessidade de faixa de cor.
- Raio
- Uma porcentagem do lado mais curto (0–50%), limitada à metade para não arredondar demais; no máximo, uma imagem quadrada vira um círculo/pílula.
- Borda (opcional)
- Mantenha a largura em 0 para apenas os cantos; adicione também uma borda e tanto a moldura externa quanto a foto se arredondam juntas, mantendo a curva interna concêntrica.
- Transparência
- Exporte PNG ou WebP com o fundo definido como Transparente para que a área fora da curva realmente seja recortada; o JPG não armazena alfa e a preenche com uma cor.
Quando usar
- Ícones de app, avatares e miniaturas de cartão
- Imagens que ficam dentro de botões ou contêineres de UI arredondados
- Uma sensação mais suave e amigável do que cantos duros
- Mockups e recursos de design que precisam de uma forma recortada
Dica
Cantos arredondados só parecem arredondados em um fundo transparente — exporte PNG ou WebP com Transparente ativado, ou os cantos serão preenchidos com a cor de fundo sobre a qual você exportou.

Perguntas frequentes
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.
