Round Photo Corners for Avatars, Cards, and Thumbnails

Use this tool to add rounded corners to image files without a heavy editor. The page starts with a moderate corner radius, so your photo immediately looks like a modern card, avatar source, or product thumbnail. Select Keep original dimensions when a regular photo should stay the same width and height, or choose a square preset when you want a square avatar, app icon, website card, or profile image. PNG and WebP are the best choices when you want transparent corners.

How to add rounded corners to image

Upload an image

Start with a portrait, logo, product photo, screenshot, or card image you want to soften.

Adjust the corner radius

Use the Rounded corners slider for a subtle curve, stronger card shape, or 50% circle-style avatar output.

Choose dimensions and format

Use Keep original dimensions for a regular photo, or pick 512px, 1024px, custom size, or original max side square for avatar and card exports.

Download the rounded image

The exported file includes the rounded corner shape, so it can be used in profiles, websites, posts, and upload forms.

Rounded corner image features

Live corner radius slider

You can preview rounded image corners in real time and stop when the radius fits the visual style.

Transparent corner exports

PNG and WebP preserve transparent corners, which is useful for avatars, badges, app icons, and website cards.

Keep original dimensions

A non-square photo can stay non-square. Select Keep original dimensions to round the corners without converting the file into a square canvas.

Square avatar and card exports

Choose 512px, 1024px, 1200px, 2048px, custom size, or original max side square when the output needs to be square.

Exact output preview

The preview label shows whether you are exporting original dimensions, a custom square, or an original max side square, so the final file size is clear before download.

Circle option at 50%

Move the slider to 50% or press Circle when you want a circular avatar-style file instead of only soft corners.

Clean JPG fallback

JPG does not support transparency, so the tool fills outside rounded corners with a safe background for photo-only exports.

No account workflow

The browser renders the final image locally, so you can add rounded corners to image files without signup or watermark.

When rounded image corners help

Website cards

Rounded image corners make blog cards, product cards, profile cards, and case-study previews feel more polished.

Profile pictures

A small corner radius can soften a square profile picture while still keeping the file compatible with square upload forms.

App icons and dashboard images

Use rounded corners for prototype icons, internal tools, dashboard thumbnails, and simple product visuals.

Product photos

Add rounded corners to image thumbnails when a store, catalog, or landing page uses soft card components.

Social media graphics

Rounded corners help screenshots, quote cards, creator previews, and carousel covers look less raw in feeds.

Transparent PNG badges

Export rounded PNG or WebP files when the image needs to sit cleanly over different backgrounds.

Original website images

Keep screenshots, banners, and blog illustrations at their original width and height when the design needs rounded corners but not a square crop.
