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

  1. Open your image. Drag it onto the tool, choose a file, or paste it.
  2. 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.
  3. 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.

Coins arrondis : ce que c'est et ses réglages

Les quatre coins nets à 90° de la photo remplacés par une courbe douce — sans bande de couleur nécessaire.

Rayon
Un pourcentage du plus petit côté (0–50 %), plafonné à la moitié pour ne pas trop arrondir ; au maximum, une image carrée devient un cercle/une pastille.
Bordure (optionnelle)
Gardez la largeur à 0 pour les coins seuls ; ajoutez aussi une bordure et le cadre extérieur comme la photo s'arrondissent ensemble, la courbe intérieure restant concentrique.
Transparence
Exportez en PNG ou WebP avec l'arrière-plan réglé sur Transparent pour que la zone hors de la courbe soit vraiment découpée ; le JPG ne peut pas stocker l'alpha et la remplit d'une couleur.

Quand l'utiliser

  • Icônes d'application, avatars et vignettes de carte
  • Images qui s'insèrent dans des boutons ou conteneurs d'interface arrondis
  • Un rendu plus doux et plus accueillant que des coins durs
  • Maquettes et ressources de design qui ont besoin d'une forme découpée

Astuce

Les coins arrondis ne paraissent arrondis que sur un fond transparent — exportez en PNG ou WebP avec Transparent activé, sinon les coins seront remplis par la couleur de fond sur laquelle vous avez exporté.

Questions fréquentes

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.
