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.

When Rounded Corner Images Improve Conversion Rates

Rounded corners give images a modern, app-like aesthetic that can increase perceived quality and click-through rates. They're particularly effective in specific e-commerce contexts where the UI design calls for a softer visual language.

Profile images and seller avatars

Circular images (50% radius) are the standard for team photos, seller profiles and brand logos on marketplaces, social media and review platforms. A perfectly circular image signals professionalism.

Product thumbnails and category cards

A subtle 8–16px radius on product thumbnails creates a modern card-like appearance consistent with contemporary UI design. Common on mobile-first e-commerce stores and app interfaces.

App icons and brand assets

App store icons, browser favicons and brand assets typically require a specific corner radius to match platform design guidelines — iOS uses a continuous rounded rectangle (squircle), Android uses an adaptive shape.

Social media content

Rounded or circular profile images, story highlights and branded content perform consistently better on Instagram, TikTok and Pinterest where visual aesthetic is particularly important.

When you select transparent background, imgflow automatically exports your images as PNG to preserve the transparency. JPG does not support transparency, so white or custom colour backgrounds will be exported as JPG or PNG.

Frequently Asked Questions

What radius creates a perfect circle?
Set the radius to 50% to create a perfect circle from a square image. For non-square images, 50% creates an ellipse. To create a circle from a non-square image, first crop to 1:1 (square) using imgflow's crop tool, then apply a 50% radius in the round corners tool.
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. Note that some platforms may override image styling with CSS — in those cases, transparent background PNG files ensure the corners appear correctly.
