Rounded corners at 25% radius
Any format works — for a perfectly even result, a square photo is easiest, though rectangular photos round just as well.
A small radius gently softens the corners. A larger radius curves them further. All the way to maximum turns a square photo into a full circle, or a rectangular one into a rounded pill shape.
Check the transparent corners against a light and dark background before saving, since transparency can be harder to judge on a plain white preview.
Rounding a photo's corners doesn't crop anything away from the middle of the image — it clips a small curved area from each of the four corners and makes that clipped area transparent (or fills it with a background color, if you're exporting as JPG). The rest of the photo is untouched. That's a meaningful difference from cropping to a circle, which removes a much larger portion of the image, including the sides — a rounded rectangle keeps nearly all of your original photo visible, just with the sharp points removed.
The appeal isn't purely aesthetic, either. Sharp square corners create hard visual edges that draw the eye and can make a photo feel like it's "cutting into" whatever's around it — a card, a background color, a row of other elements. Rounding those corners softens that boundary, which is part of why rounded corners have become the default look for app icons, chat bubbles, product cards, and thumbnails across nearly every modern interface. It's a small detail, but it's one of the fastest ways to make a plain photo look intentionally designed rather than just dropped in.

There's no single correct radius — it depends on what the image is for and how large it will be displayed. As a general guide:
| Radius | Effect | Common Use |
|---|---|---|
| Small (5–15%) | Subtle soften, corners barely visible | Product photos, screenshots, thumbnails |
| Medium (20–35%) | Clearly rounded, still a rectangle | Cards, website images, app banners |
| Large (40–49%) | Strongly curved, near-oval on rectangles | Feature images, highlighted content |
| Maximum (50%) | Full circle on a square photo, full pill on a rectangle | Profile pictures, avatars, icons |
If you're rounding a photo for a profile picture specifically, set the radius to maximum on a square image — that produces the same full circle that WhatsApp, Instagram, LinkedIn, Discord, and most other platforms already apply automatically to their profile photos, so you can preview and adjust it yourself before uploading rather than leaving it to the platform's own crop.
Profile pictures are the most common reason people reach for a maximum-radius circle, but a smaller radius shows up constantly in places that are easy to miss:
App icons use a consistent, moderate radius that matches the operating system's overall icon shape.
Product photos often carry a small radius so thumbnails feel like part of a cohesive grid rather than a stack of sharp-edged rectangles.
The boxes that hold a blog thumbnail, a team member's photo, or a feature image commonly use a medium radius to match the rounded corners of the card itself, so the photo doesn't look like it's fighting the container around it.
Presentation slides benefit from a small-to-medium radius on photos, which tends to look calmer and more polished on screen than a sharp rectangle.
Matching the radius to where the image will actually appear is more important than picking a number that simply "looks nice" in isolation — an 8px radius that looks barely-there on a large banner can look identical to a much larger radius once the same image is shrunk down to a 40px thumbnail.

Expert advice to make your WhatsApp profile picture look stunning every time.
A square photo rounded to maximum radius becomes a perfect circle — this is the standard look for a profile picture or avatar.
A rectangular photo rounded to maximum radius becomes a pill shape, with fully curved short edges and straighter long edges, rather than a circle. This is common for banner-style graphics, not profile pictures.
Both start from the same idea — clipping part of the photo's edge — but they solve different problems. A circle frame is specifically about creating a full circular result, typically for a profile picture, and usually includes an optional border or ring around the edge. Rounded corners is the more flexible, general-purpose version: it works on any radius from barely-there to full circle, and on both square and rectangular photos, making it the better choice any time you want something other than a perfect circle — a card image, an app icon, or a photo with just enough softening to feel less sharp-edged.
Applying a large radius to a rectangular photo expecting a circle, when what actually results is a pill shape — crop to square first if a circle is the goal.
Exporting as JPG when transparency is needed — JPG doesn't support transparent areas, so the rounded corners will fill with a solid color (often white or black) instead of showing whatever background you place the image on.
Choosing a radius that looks right at full size but disappears or looks inconsistent once the image is displayed much smaller, such as in a chat thumbnail or app icon grid.
Rounding a photo that still has a visible straight edge or border baked into the original image — the rounding clips the photo's shape, but it won't remove a rectangular border that was part of the photo itself.
Setting the radius to its maximum on a square photo produces a full circle. On a rectangular photo, maximum radius produces a pill shape instead — crop to square first if a circle is what you're after.
No. Rounding only clips the four corners and makes that area transparent (or fills it with a color for non-transparent formats) — it doesn't compress or resample the rest of the image.
This happens when exporting as JPG, which doesn't support transparency. Export as PNG (or WebP) instead, and the rounded corner areas will stay transparent so they blend into whatever background you place the image on.
A medium radius, generally in the 8–20 pixel range depending on the image size, matches most modern website and app design conventions without looking overly rounded.
This tool applies the same radius evenly to all four corners, which covers the vast majority of use cases. Selective per-corner rounding needs a more advanced image editor.
They're related but not identical. Rounded corners can produce anything from a subtle soften to a full circle, and works on rectangular photos too. A circle frame is specifically built around producing a full circle, often with an added border, and is the more direct choice when a circular profile picture is the only goal.
