Frequently asked questions

What radius creates a perfect circle?

Set the radius to 50% to create a perfect circle from a square image. To create a circle from a non-square image, first crop it to 1:1 using the crop tool, then apply a 50% radius.

Can I use rounded corner images in PrestaShop or WooCommerce?

Yes. Upload rounded corner images (as PNG with transparent background or with white fill) directly to your e-commerce platform. The images will display with their rounded corners intact.

What is the best radius for product thumbnail cards?

8–16px produces the most professional results for product thumbnails. This creates a subtle card-like appearance without making the corners look overly rounded.

Does adding rounded corners reduce image quality?

No. The rounded corner operation is applied at full image resolution without any compression.

What background should I choose — transparent or white?

Choose transparent (PNG) if your images will be placed on coloured or textured backgrounds. Choose white if your store has a white background and you want to export as JPG-compatible files.

Questions fréquentes

Quel rayon crée un cercle parfait ?
Définissez le rayon à 50% pour créer un cercle parfait à partir d'une image carrée. Pour créer un cercle à partir d'une image non carrée, recadrez d'abord en 1:1 avec l'outil de recadrage d'imgflow, puis appliquez un rayon de 50%.
Puis-je utiliser des images à coins arrondis dans PrestaShop ?
Oui. Téléchargez des images à coins arrondis (en PNG avec fond transparent ou avec remplissage blanc) directement sur votre plateforme e-commerce. Les images s'afficheront avec leurs coins arrondis intacts.
